Hi guys,

i am sorry i really don't like asking stupid questions but i searched and found nothing.

1. Does an R34Gtt have more than one fuel pump? or does it use a single pump?

The reason i ask is i have one here and was going to fit to my car but after taking my pump out, I noticed it is about 60% smaller then the pump that is already in the tank.

The pump i already have is the same size physically as an R31 pump. and the R34gtt pump is tiny in comparrison.

So if someone can confirm that the R34Gtt only uses a single pump, and that it is a really small looking pump that would be great :P

cheers!!!

once again, sorry for the really stupid question.

The pump on the Left is the one i think is the R34 gtt pump and has thepart number:

UNISIA JECS

A42H24

000

FAFB100

9530N

The other pump is an R31 pump (not the pump i am currently using but the same size) the one i am using is not regulated like the R31 pump in the photo

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
