I had a similar thing on my old 850.

For a day or two.... load of rubbish.... Hamish spent an hour or two trying to set it up, junked iit, and she ran perfect first time....

personally, I wouldn't bother....

Cheers Paul won't bother then.

I had a universal one. Used it for 10mins, car wouldn't run properly now its in the bin. I use a 2wd cossie weber one. Cost 20quid and works a treat.

That's interesting, I used the same one and couldn't get it to work right at all.

never had a problem with it:)

If I set the pressure somewhere near right at tickover, then it would go way to high at high revs, whar pressures is yours working at?

now thats a cracking question!!! :lol:
no idea?????

I got it, bolted it on and the car ran fine,infact I raced with it on last year.
only the other day,we wound up the pressure a bit more and it reacted and the car runs fine,no problems:)

Mine would only run properly if I pulled the vac pipe off it.

red pipe goes to the vac tree
the opposite pipe goes to the tank return
and the pipe out of the bottom,goes to the fuel rail

Thaks johnny say ive seen a few ways your way is the way im doing mine.

mine runs better with the vac pipe off because then it holds at what i set the fpr too say 4 bar all the way through the rev range and easier to map too.with the vac pipe connected it would flood the car with fuel because it was rising the rate up to 6 bar lol

I understood thats the purpose of them????
to raise the pressure as the revs went up????

maybe I have the only working version?? ;)

wonder if Sam made some magic modification to it when he fitted it :P lol

you can use it both ways mate if u are using small injectors then yes they work well but im using big injectors then they have a habbit of ouerfueling higher up the rev range .mine works well at keeping a constant pressure like 4 bar
