i have a mallory 110 7 psi fuel pump and a holley non return regulator. I have it regulated to 6 psi and when the car is cold the russel gauge shows 6 psi and then when i come back from a rip i pop the hood and the gauge is bottomed out at zero..when car is cold it shows 6 psi...my fuel getting too hot under the hood and pressure drops??? I dunno anyone familiar with this..its on a 302 with an eddie 650 carb.

Also i was out yesterday in ole dirty and under low rpm the engine/ car would hickup a couple times and then drive normally and would perform normally under high rpm..either spark or fuel..i pulled each wire to see if i had a dead plug or wire/cyl and each plug wire pulled made the car run rough. so i know the spark is there under idle

it also has a f303 cam and i am not used to a 302 pushrod motor with aftermarket cam, will that give the engine a little more lack of a better word movemnet on idle...?

thanks in advance
