Quote: I picked up a summit dualfeed line with filter and gauge and a separate line to tape the gauge to the windshield. I got a constant 4 psi with no drop in pressure,engine still falls at 5 grand. I took theline off and installed it to the feed line and get a chatty 6.5 psi. I also replaced the fuel pump rod with a mancini one.
I would verify the needle and seat are correct. There is a certain size needed to allow enough fuel to enter the bowls. If to small you may be starving for fuel even though you have pressure. Pressure is flow to resistance.
I've thought of this but not checked into it yet.bought a used carb and rebuilt it with a fast kit. I still think it's a fuel issue,car dose not sputter or pop,just sounds like running out of fuel. cant find info on what size needle seats are used.???
