    Exclamation Fuel Pressure Reg Questions

    Hey guys, need to know a few things, some might be a bit beginner so excuse me for that.

    1) I have a Malpassi Reg, need to confirm which hoses go where?
    1 hose on top, which i know is vacuum, 1 hose on the bottom, which i assume is the fuel feed line, and 2 at oposing sides in the middle, one of which im assuming goes to the fuel rail, and the other either blanked off or for a fuel pressure gauge. Is all that correct or am i way out of line?

    2) Its going in a VS 5ltr, WHERE THE HELL DO I MOUNT IT?!!!!!!
    ABS is such a prick, gets in the way of everything, where is a good idea to mount it? Or could someone show me some pics of there setups?

    I know there was at least another question i wanted to ask but I have forgotten, so I will add it if i think about it

    Cheers Guys,
    Geoff

    geoff i mounted mine on the opposite side of the motor to where the standard one sits.

    i think you may be correct with what your thinking but im not too sure. but it does sound like the way i had mine set up

    So you mounted it on the passenger side? Whys that? Would running hose that long cause it to lose pressure or anything? Is it best to keep the hoses as short as possible or what?
    You got a pic dave?

    No one at all????!?!!!

    At the moment I am thinking about mounting it on the passenger side next to where the fuel damper is and running the hoses a bit longer, is this going to be a problem at all or is it all good?

    Should have one main feed line, a vacuum line, a fuel return line and a fuel rail line i guess...

    How big is it? got some pics of your bay and the reg so that we can all have an approximation as to where it should go...

    hose length shouldn't effect it but less is always better. try and keep em away from heat sources.

    Ended up mounting it on the passenger side of the motor, but the hoses wernt even that long, kept them as short as i could, i reckon the hoses are shorter this way that mounting it near the ABS. Hopefully all goes well when i start it up
