Top End Miss

well at a gallon a minute thats roughly 60 GPH which isn't very good... so im left with to things... One there is a restriction and Two the pump is going out...

now i replaced the Etire fuel system, brand new lines, pick up, sock, filter, rubber lines... and emptied and cleaned the tank... so what gives!

im gonna check all my rubber line to see if its closing up and replace if necessary... then throw on my holley black pump and try again...
Sounds like you don't have enough volume. I found this: http://forums.corvetteforum.com/c1-...5-hi-volume-mechanical-fuel-pump-testing.html
About half way down the first post he mentions how much fuel you should pump for a given car. He's talking faster, more powerful cars, but it seems you're right, the 60 gph you're seeing isn't enough.
New parts don't mean good parts. Go through your delivery system closely.
I don't have anything running to do a test on. You know anyone whose car you could test to compare?
