I installed an elec. fuel gauge (0-30) in march, everything was fine.
average fuel pre. was 12 at idle, 18 crusing at 1750 rpm, and would clime as
high as 24 with wot. coming home a week ago, I was accelerating onto the
interstate, when the fuel pressure jumped to 28psi egt was 680, boost was
15. the fuel came back down to it "normal" range. the next morning I was
heading to town, fuel pressure climes to 27.4 after about 2 miles it shot up
to 33 before the gauge went into error mode. it has been that way since.
when I crank it up in the morning fuel pressure is 26.x, any increase in rpm
causes the gauge to top out.
I removed the sending unit from its mount on the fender and installed my
fuel injection test gauge, Bounce! the needle looked like a fan blade, up to
40psi down to 15psi, I also noticed the fuel line was throbbing. I am
thinking of replacing the fuel gauge with a manual gauge, but all that
needle sweep has me nervous.
