Fuel Pressure Regulator Type

  1. #1
    Am just after a favour - if anyone has a fuel pressure regulator that they could quickly measure I'd appreciate it!

    Am looking to order a fuel pressure regulator housing to go with some throttle bodies, jenvey list 2 types:

    Pressure regulator housing with -6 fittings. (9.4mm Bosch) RH01 £ 39.00
    Pressure regulator housing with -6 fittings. (7.5mm Bosch) RH02 £ 39.00

    Am just wandering if anyone can quickly measure the end of the fuel pressure regulator and tell me the diameter? 7.5mm or 9.4mm?

    Much appreciated if someone can quickly do this for me !

    Just to save confusion, you've listed -6 for both sizes. The top one is -6 and the bottom is -5.

    Unfortunately not much use to you. (although i'm fairly certain the standard FPR is 8mm connectors - so -5, but get someone else to confirm)

    I think the -6 refers to the connectors on the remote fpr housing for the fiuel line fittings.

    As I read it is that 7.4 n 9.5 I is the diameter inside this housing that the end of the fpr fits within. Could be wrong.

    Sorry - probably not made myself clear.

    -6 fitting can not be both 7.5 mm, and 9.4mm.


    How to work out the "-" dash sizes;

    1 inch = 2.56cm = 25.6mm

    Divide by 16 = 1.6mm

    Dash 6 ("-6") = 6 x 1.6 = 9.6mm
    Dash 5 ("-5") = 5 x 1.6 = 8mm
    etc etc

    As I read it The diameter I'm after is 'X'

    Ideally am just looking to order the correct size fuel pressure regulator housing from Jenvey, as well as a sausage filter base plate.

    Sorry I missed your post last night Willsy - if you don't mind posting the diamter of the frp you've got that'd be great!
