How to: fuel pressure regulatot?
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
I think those are the minimum pressures-so if you setup a fuel pump that always supplied 3.5bar you would probably be okay. I'm not an expert but just guessing.

I was under the impression fuel pressure was raised with revs to ensure complete element filling as time available to do so reduces with rev rise.
I don't think increasing fuel pressure with boost would have any effect on quantity output.
For over 15psi a rising rate fuel pressure regulator from a fuel injection system is required because cabs systems rarely pressurise the float bowl to over 15spi, if my memory from turbo austin mini days serves me correct.

hy there,
well , in my setup i eliminate the lift pump and bought a BMW fuel pump, actually it is not a BMW pump, is a pump suitable for BMW cars (gas) something like a coca cola can, 100€ more less . this pump can be set in series in the fuel line. is fantastic can deliver 3to5 bar wich is to much in idle. very often i end up with burst pipes. the reguator i´m using is a 0,2 mm hole in the fuel filter exit. to avoid busrting the piping i have a swich to turn it on when i really need the power, and belive me it is noticeable.
regards

What about this??
This actually made for diesel(Cummins, Duramax bla bla bla)
Read somewhere that the rack can stick if you run 3 bars at idle.
The thing my man from sweden is searching for is a progressive FPR
http://www.biltema.se/sv/Bil---MC/Bil-ti...tor-79741/
I will be using a 044 copy for my superturbobuild. Norwegians have used it with success
http://www.biltema.se/sv/Bil---MC/Bilres...ump-52250/
No need for a progressive FPR. A progressive one will up the pressure with a constant like 1.4 or such. So 1bar boost will give 2.4bar fuel pressure, 2bar boost will give 3.8bar fuel pressure (if the no boost fuel pressure is 1bar).
A normal (linjär in Swedish) FPR will just ad the boost in fuel pressure so the same scenario will be 2bar and 3bar fuel pressure.
A normal Bosch 044 or a good intank pump is a good solution together with a good quality FPR of your choice.

(02-17-2014, 01:49 PM)Tito Why 1 bar on idle? I don't think its a huge problem if you just have 3 bar from a electric pump on idle? or am i missing something?

(03-03-2014, 04:40 PM)mantahead i did some experimenting with feed pressure and once run 4 bar, even at idle. leak off pipes like to blow off
this was the only problem i had.
I use two 044 copy pumps with bypass fuel regulator before the injection pump. The regulator add the fuel pressure vs boost and it returns extra fuel back to tank. I also make Arduino based controller for the lift pumps. When I drive <1,5bar boost only one pump works and after 1,5bar boost Arduino starts the second pump also and both pumps work. This because I don´t have fuel cooler and there will be plenty of fuel what goes through the FPR and it warms the fuel very much. It also saves the pumps to not to work that hard all the time. Fuel lines are 10mm ID from and back from tank. I use 1 bar fuel pressure in idle and 3bar with full boost. Arduino controlling is now on process and we´ll see how this setup works when spring arrives here.
There's no reason to have significant pressure on the IP, positive pressure (indicating flow) is enough. Those 3bar setups are just overkills. Of course you need fuel lines big enough to have flow.
I've dynoed 450hp with 0,1bar between filter and IP at top revs
Gasser fuel (injection) pumps aren't great if the car has to see winter driving.

Holley HP-150 is a decent pump, one just has to remove the inlet screen filter for diesel use.
Max injected fuel quantity doesn't depend on inlet pressure in (practically) any way. All you need is that the injection pump is topped up all the time. You need flow, not pressure. Don't know if dieselmeken modifies the stock return banjo, which has a kind of pressure valve to restrict return flow.
I'm planning to use a holley black as it's rated as 140 us gall per hour at one bar. That is a lot of fuel!

According to Göran, it needs to be fed with 1bar at idle and 3bar att max rev.

Oh, How long have you been running with the pumps?
Do you have the FPR on the fuel in or out?
Got any vids of how it more in action?
Thank you

Just this spring I get this setup working. FPR is before IP and the extra fuel goes back to tank. SJ4000 action cam is ordered and coming. When I get that I´ll post some driving clips. I tried to film with one hand and steer one hand but the film looked ridiculous because the phone spinned with my hand and filmed the roof, doors, floor and windows Have to keep focus of driving.

Tell me how you can have 3bar in the IP with the regulator before the IP. That's just not possible. The FPR needs to be on the return line. And yes we have tested this in Dieselmekens test bench. You do need 3bar to get the right "filling" of the elements.
Look at the picture. Both pictures show the regulator AFTER the fuel rail (or IP for us dirsel guys). Only in the second picture you are fooled by the external look of the FPR.
Sorry about the delay of the reply. My "compound STC" is sold and if the new owner wants to tell more about his modifications he will write here(forum reader). I just told what my fuel pressure gauge told me.. I had modified banjo bolt after injction pump and fuel pressure regulator before IP, believe it or not.. and it took info from boost and added fuel pressure. It was almoust 3.2bar so I had to turn it back a little bit not to break IP´s gasgets. Because some say that over the 3bar fuel pressure breaks the gasgets sooner than later.
Here is some film how the dieselmeken IP rocks with 3bar fuel pressure(Had to turn boost little bit moore after that ):

Where did you have your gauge?
Just an FYI here.. If you get a fuel filter from most any 1998-2005 Mercedes it has a built in FPR set at 3 bar. They are only about $60 and all hose barb fittings.
