yeeehaaaa!!!!;D
found the problem~! 1st, my new autometer fuel pressure gauge showed up!
1st order of biz...install gauge!
took it for a test, floored it a couple times.
cruising speed=35psi
shifting gears=30psi
idling=38psi
knocking the bottom out!...PRESSURE DROP BELOW 20psi! almost zero!!
came home to try something else. i found out today the holley red pump had a small filter/flame arrest screen internal.(never knew that, ive been using this just over a year, cant imagine the PO checking it for the 4 yrs head had it)
the pic should say enough!!!
it looked like a strip of elec tape jammed between the screen and inlet side of housing!! but it wasnt tape, it had numbers printed on it like it was part of the original gasket. removed it and cleaned the housing and screen.
decided to take it for another ride before bypassing accumulator. GOOD THING TOO!
next ride...
cruising speed=38-40psi
shifting gears=35psi
idling=38-40psi
KNOCKING THE BOTTOM OUT....40-43psi!!!!!
no drop in psi, no back fire,no surging...ran the strongest yet! 2nd gear broke the tires so loose! killed 3rd and broke them loose again!!!
thanks for everyone's help today! so for right now, the accumulator is gonna stay...unless something else pops up. but, for now-im happy. it amazing what the right tools can do and provide(ie. fuel pressure gauge!)
