What fuel pump are people using?
Im sending my pump out to Dieselmeken tomorrow and I saw people were recommending that I get some kind of lift pump. So what are people using? I also noticed that there is some kind of fuel heater inline, can this be deleted? Or what is this thing? Its an us spec 87 300 sdl.
I have bought a holley Black pump - not used it yet.
Remember to use a pump that is diesel compatible. If using biodiesel, your pump MUST be compatible. Also, a 100 micron prefilter is best to have in line before the pump.

Any good recommendations for biodiesel pumps? Also can you tell me more about mounting an intank pump? How easy is that? Just get a Fuel pump and wire it in?
Ah the 190 has an in-tank pump from factory, easiest to buy an inline pump from something German (so it will be a Bosch pump) then fit it in the fuel line between tank and IP, some people think by the tank is best, personally I think by the IP is best because its easier to wire and OEM lift pump draws from the engine bay, easier/safer to mount relay/ign. switched live also.
Do we need to use a big pump or will the actual injector pump still be doing most the work?
If you want a biodiesel pump, look at the Airdog Raptor pumps. Some places sell pumps only so you don't have to pay for all the extra hardware. Ive been running one on my pulling tractor for a couple years now and never had a single problem with it.
Airdog/Raptor has gone way downhill. Mine lasted less than a year, the replacement was junk & then they lost my warranty card. The downward spiral started about 2 years ago after a licensing contract to Pureflow.

I tried to defend them, due to the former owner (Licensor) getting involved, but they still have major QC issues.
The issues are the seal between pump & motor, regulator needing to be constantly adjusted & machining burrs in some parts. People in the Cummins world will not touch them.
Fass makes a superior product at a comperable price.
For best results with any electric pump, it is best to mount as close to the tank as possible, as they push, rather than pull.

Yeah, the worst part is that AFTER sending me a warranty pump that fluctuated from 4PSI to 21 PSI at idle & was at 0 PSI anything above idle, they conveniently could NOT find me in the computer system. That has happened to MANY others. They admitted that they have a problem to 1 CF member (Machining burrs) but didn't offer him any compensation after he got an HD system from the Licensor. He went through 5 pumps in 2 years.

Good point regarding electronic pumps pushing rather than pulling, performance (flow & pressure) would be alot worse drawing through 10 feet of 3/8 tube!
Im putting a pump off of a 1994 Chevy 6.5l they are cheaper and stocked at almost any auto part store. the one in my chevy worked for years with no problem. so hopefully this one works just as good..
I use a BOSCH 044 which works fine. I used one in my WVO 300D for 4 years and almost 200K with no issues (Waste Vegetable Oil 1 Bar @70C). Don't get wrapped up into using some super fancy $$$$ fuel pump.....
After a nice little visit at the diesel guru Mr Dieselmeken and some testing of fuelpressure I can highly recommend that you all go for 3bar of pressure.
In our om605 build we are using an AEM 320lph intank pump, an Aeromotive fuelfilter (the steel model, not the paper one) and an Aeromotive FPR to controll the pressure.
BUT make sure to do a separate return line from the injectors back to the tank.

Yes that is a problem. Higher fuel pressure will make the rack movement heavy. But for sure, if the pump builder calibrate rhe pump for 3.5bar or 4bar I reccon that's ok. However I can't say for sure.

Yeah I was also curious about the advantages? Im also curious why higher pressure would make rack travel harder. I guess I just dont know the inner workings enough.
We tested the rack movement at different fuel pressures, big difference really. About the fuel pressure it's to give you maximum power no matter what RPM or load you are running. While testing we saw some major advanatges to go 3bar instead of 1bar. And while testing live in our om605 we noticed the same differences at different fuel pressures as the test bench showed us.
IIRC the elements fill more completely or something, too at higher fuel pressures
They're flying around like mad in there and make a vacuum on every down stroke that is broken by fuel pressure as the top of the element clears the fill hole. Makes for a cavitation prone environment.
I used dual Bosch 044 pumps (copy but almoust the same specs, 240l/h <2bar) in paralleling with recirculating fuel regulator before injection pump in my compound om606 C126. Fuel pressure with idle 1,2bar and with boost 3bar. Worked great with Dieselmeken´s 8mm.
