Fuel pressure jumping
Posted 26 December 2012 - 05:50 PM
prep'n for a Weber swap in the next week or so, so I put a fuel pressure gauge inline to the carburetor just to see where it sits.
it pulses quickly between a little above 2psi and 3 psi.
question 1) is the pulsing a sign of fuel system problems? It is a cheap gauge so I wouldnt rule out some slight inaccuracy.
question 2) is the spike to 3 psi what I should consider the fuel pressure? or the low spot? Im guessing that since it pulses very fast it wont make a difference since the bowl will still have fuel, and im not going over the max pressure required.
question 3) is there anything I can do to make this more stable. My initial plan was to run a return line filter, so I can restrict the return a bit to try to get the pressure up to 3.5ish. I can also run dead ended since the pressure isnt over the max.
I just got the Weber Haynes manual so ill check it out tonight, any advice would help though.
