Fuel Pump Volume test?
Posted 12 January 2004 - 07:44 PM
i got an 85 Subaru Brat with the 2 Barrel Hicrappy.
I've had a problem with my brat dying in turns and rough idle.
Im currently cursing the fuel pump for these problems
But i like to get some input from you guys
1)I got a rebuild kit and put everything together correctly
A) Im very mechanically inclined,so i knew what was goin on
2)The fuel level in the bowl is low regaurdless how many times
I've adjusted it.
A)many times ive adjusted it
3)Both the fuel filters have been changed
B)is there some kind of filter inside the tank
C)fuel quality is good
4)Did a fuel psi check and came out with 2psi and the manuals
say 2.6 to 3.3
A)does this 0.6 make a difference?
B)Is there some kinda Pump Volume Specifications
C)is there some kinda of fuel pump relay that would
cause this problem
C1) If So where is it located
I know this is fairly drawn out but any help is greatly appreciated

You can have 1000 psi of pressure - won't matter if your volume is too low - the engine will use it all up before the pump can refill the bowl.
If you want to test volume - run it into a gallon jug till it's full and time it.....

remember all the posts you see about webers with problems, before you go for a weber, thinking it will make your world a better place.

Also add to that the fact that I have heard NO reports of incorrect float levels on factory built Weber's - I think their quality control on something like that is probably very good - considering their reputation in the market. I think we would be hearing Jeep and Toyota people screaming bloody murder if that were the case.

D'OH anyhow now im having the typical hicrappy
problem of gaining rev in left hand turns and losing them in right
now i have something else to figure out but hell at least its drivable now......

There are also two places on the tab to bend and make adjustment.
I'll see if I can find the sheet from the rebuild kit and scan it for you.
At the very least, it sounds like you need to have a higher fuel level.
