My 340 is running hot I think.. I need a sanity check.

I don't have an issue with fuel pressure it's constant 5-7.. My logic for placing the filter there was cooling
.
Can you elaborate on why You recommend not to have it before the pump?
Cause mech pumps aren't designed to pull fuel through a filter, only push. You'll get high speed lean out. Also, put the biggest seats you can in that holly and limit the fuel pressure to 5.5lbs.
