I've used electric oscillating pumps on other things (transfer pumps) and they are junk at best. I had the Cummins pump in mind but it is only set to pump 15psi and has a 5psi high flow pressure. I want to run 25-30 psi across the RPM range.

How about it? That would deliver a smooth fuel flow and constant pressure to the injection pump.

The old style banjos can be disassembled. Pull the spring and stretch it (to 25-28 mm expanded length).

I have two pumps on my Dodge CTD. I run 27psi until I put my foot on the pedal. I have a stock pump in the tank and a BD Diesel transfer pump on the side of the Engine Block. I did this because my first VP44 IP starved and died. This works great! Im thinking of adding a pump to my 240D, it dies sometimes trying to pump veg oil.

Benefits are numerous. Idle is improved in terms of smoothness, since the fuel pressure is near constant compared to the very pulsed output from the factory pump. "Throttle" response and tip in are also improved for better drive-ability. Best of all is a noticeable increase in high rpm performance, and more power overall. It is subtle at first, but noticeable, becoming more and more apparent as the rpms increase. To note, this is with the 5.5mm elements on a w123 MW pump.

11-23-2009, 12:36 PM #17For the last ~20K miles, I am using a Bosch external electric pump for a petrol engine. I forget the listing, but it is for a CIS application, raises the pump pressure to just above the regulator at the outlet banjo, and has no problems otherwise. Current draw is <5 amps since the pressure is low as compared to a CIS car, and is quiet as well.

Precisely, I found someone's Mechanical Engineering PhD thesis that discusses the design parameters of such a device, and I used these to size one for this application. I have all the parts, possibly even a usable motor, although it might not be powerful enough. Unfortunately, I have had zero time to build it, and probably won't get around to it for quite some time. If/when I do I will post results.
Its good to hear someone had some success replacing the lift pump, however I cannot imagine how/why it would affect a difference in power output, unless there is an air leak somewhere, or the elements are creating sufficient vacuum on the downstroke at high rpm to vaporize the fuel... Recall that fuel isn't compressible in liquid form.

The powerstroke high pressure pump is a 40-60 psi spec. Big money though, unless you rip them out of a yard. Its like 2-300 bucks. For that I would spend some more and get an adjustable FASS or RAPTOR pump.

Some things to think about:
1. What is the max fuel flow required for a given set of elements at max power/RPM?
My rough calculations indicate a need for 100+ gal/hr at 6000 RPM with larger than stock elements @ max power. Anyone have a stroke length or actual CC rating for these pumps at max?
2. What is the correct pressure to achieve adequate element filling at high RPM's?
Forced is saying 30 which sounds fair. I also think we could use the trucks as a model - my F250 pump puts out around 65 PSI. Anyone know the GPH spec. for the PSD pump?
3. How do we regulate the pressure?
Do we modify the stock relief valve or plug the relief port and use an external bypass regulator? The PSD guys have been modifying their fuel systems with external regulators and removing the "ball and spring" type stock regulators with good results. Only thing is that these regulators are pretty expensive.
Also consider that we will have to wire in oil pressure switches and relays for safety to shut the pump off when the engine quits. I can also see adding a curcuit to the GP relay to get the engine going before the oil pressure comes up.
All in all, it's looking like a $500 upgrade once it's all said and done. But it may be required if the existing system doesn't meet the engine's fueling requirements.

Ive seen somewhere (did try and find it....) that a pump flow of 170ccm per 1000 strokes, per element at WOT and Full delivery is what one of the Finnish guys was running on his 605 Super-Turbo, pushing summit like 450 BHP--Think thats what it was anyway, Defo 170ccm/1000 though.....
Its always a good idea to get rid of that pulsing from the standard lift-pump, fuel-press is all over the place on std installation, and while this doesnt seem to make a Huge difference to a Standard engine it'll prolly affect a Tuned motor quite badly.....

I don't have a good feeling with gasser pumps. Diesel has higher viscosity and the pump is running all the time (against pressure).
I have a "tooth gear" pump from CDIs on my table. This is a small "hydraulic" pump that I will drive as a test with a wiper motor, later maybe mechanically from somewhere on the engine. The pump has an adjustable pressure by-pass valve. Mechanically driven by engine rpm also makes some sense.

I don't have a good feeling with gasser pumps. Diesel has higher viscosity and the pump is running all the time (against pressure).
I have a "tooth gear" pump from CDIs on my table. This is a small "hydraulic" pump that I will drive as a test with a wiper motor, later maybe mechanically from somewhere on the engine. The pump has an adjustable pressure by-pass valve. Mechanically driven by engine rpm also makes some sense.

Remove the stock lift pump and replace it with a cover plate, continue to use the stock fuel filter. Upgrade all high pressure hoses to fuel injection hose. But you have the right idea.

Hydraulic oil is still a thicker viscosity. Might I suggest a "Jabsco type" nibrile impellor (Marine raw water & oil/diesil transfer) type pump as the volume supplier to the gear pump with a bypass regulator? It might make the most sense. You can already get them with the right electric motor on them. I have several(for oil changes on marine engines) & 1 is rated for 100 GPH for cold oil. That would guesstimately be 150 - 174 GPH of diesel. "Globe impellor" in Brocton, MA. has nearly indestructible impellors that can pass lots of sand with very little change in performance(34' sportsfish grounded in the middle of the ICW north of the first bridge in Daytona FL with twin cummins. Had 1 engine running for 4 1/2 hours while dragging ourselves off the sandbar with 2 anchors & the windlass, traveled another 500 miles to port & pulled both impellors & could barely tell the difference). That gives you delivery, pressure & regulation. I wonder if the right "Jabsco/Sherwood" type pump might even be able to do delivery & pressure? If mechanical drive is wanted, they are simple to install in any belt system.
Options:
1: "Transfer/Jabsco/Sherwood" type pump with "Globe or Nitrile/Nibrile" impellor feeding volume to Gearotor hydraulic pump with bypass regulator (Both pumps can be run electric or belt[Applies to all])
2: Large enough "T/J/S" pump to easily supply volume & delivery pressures across the board with bypass regulator.
3: Hydraulic pump alone ( might have problems with viscosity, wear, priming & draw)
OK, there's my rant. "You may be right, I may be crazy" You know the rest...

I have recently bought a whole pile of viton rubber hose to replace my whole fuel system lines to be able to run biodiesel. Will this hose work? Will it say on the hose what pressure it's rated for? What pressure rating should I be looking for, one that exceeds the max of the pumps rated psi output?

The injection system shouldn't need any more than 30psi so I doubt your viton hose will have a problem with the pressure.

Most standard "fuel hose" like you'd get at a parts counter will have a working pressure around 50psi and a burst pressure around 150psi. It all depends on the material and design/standard.
The injection system shouldn't need any more than 30psi so I doubt your viton hose will have a problem with the pressure.

The regulator front is something I'm still not sure about. I'll initially try using the stock "regulator". If that doesn't work, I'll probably use a setup like a DIY boost controller. That's basically all a regulator is for us diesel guys. Gassers have a regulator that will increase fuel pressure when there is no vacuum in the intake manifold (automatic "fuel enrichment" under load), which makes those aftermarket regulators expensive, and is something we don't need at all.
My $.02
(06-27-2010, 04:44 AM)tomnik I don't have a good feeling with gasser pumps. Diesel has higher viscosity and the pump is running all the time (against pressure).
Diesel is also a much better lubricant. I don't think we can say one way or the other until someone has some miles on a gasser pump.

That sounds like the high pressure pump. I don't think that will work well at all. Two things, it is designed to produce 1600 bar, and my CDI has a fuel pump in the tank to provide diesel to the high pressure pump. Basically, it is probably horribly inefficient at 30psi, and I have no idea if it is self priming.

Personally, I plan on using the CIS fuel pump out of my parts '90 300TE. It is a stock setup so it already has all the mounting brackets, etc. which should save some time. Also, it should have no problem running any pressure I want, and it should be CHEAP to buy even if I didn't have a parts car to snag it from.

Nah, The pump Tomnik has is the CDi Camshaft-Driven 'Lift-Pump' its a small internal/external gear pump intended to Feed the Rail Pump with fuel...
Its Not the Rail pump itself or the elect pump from the tank, this is the Engine-Driven pump which raises pressure prior to the rail-pump, and will be Most Suitable!

Your 320 is from '05 and I believe 3rd generation common rail.
The gear pump has clamping connections that are for sure not rail pressure, but it is small and has an adjustable pressure limiter integrated (and it is available here for little money).

It should be a self bleeding affair at that point. The pump will act exactly like the hand pump. As soon as it is turned on it will start pumping fuel through the system and force all the air out.

So just turn the car to "on" for a few seconds and the air will just push itself out... How does the system maintain the 30 or so PSI if its bleeding back to the tank? Is the fuel pressure held at 30 PSI by that banjo fitting you guys were talking about like a pressure regulating spring in the engine lubrication system? I assume this is the spring Forced was talking about stretching a bit to boost the pressure in the fuel feed side of the system..

I could easily try the RetroTek Speed pump and regulator since I am the one who makes them but I'm not in the "Super Turbo Diesel" category yet therefore I do not have the need for this type of setup.
if you guys want, I could try it out for ya.... when you bypass the mechanical lift pump, can it run dry? or does it get lubricated with the fuel moving through it? who sells a block off plate for it?

it'll probably be set to 25psi all the time. can a lighter spring be installed to account for the higher viscosity of the diesel fuel?

the fuel supply to the IP is pretty weak on mine. It bogs on the hills bad. I am planning on getting a good electric fuel pump and I'll need some sort of regulator on the return. I'm sure an adjustment from 25-75 psi is enough to tune the differences between gas and diesel out. I'll be purchasing one of these regulators for sure.

Personally I would only use the one rated for diesel fuel which is the fuelab fpr.

There shouldn't be a compatibility issue everything is Viton
Here is a better link: http://www.professional-products.com/fuelregulators.php
I'm am not trying to sell these, just pointing out that they cost about $100 whereas the fuelab one costs $160
