Fuel system

[brent flynn]

Chances are, a Mallory Comp 140 and The Volumax Holley Reg, #8 lines, front to back, with low restriction filter(after the pump), and #8 line from 8gallon fuel cell, would feed my E/SA 400 Pontiac? Im trying to decide what to do, for a pump , to get started...Or just spend 60.00 more and get a Magna Fuel Quickstar 275, and be done with it? Thoughts are appreciated...

Brent: I would check the system that you currently have first. The system you have is very similar to what I had years ago and it wasn't bad. I think it's a good idea to do a fuel volume test to see how good your system is. If you can pump a gallon in 30 seconds or so, that's pretty good. Just unhook the fuel line from the carb (so the fuel does go thru the regulator). Scrutinize every single fitting, line and filter that the fuel passes thru by measuring the I.D. of each. Different types and brands of regulators, in particular, can be very restrictive. Like previously stated, Q-Jets require a very good fuel system due to the fact a single needle and seat and single fuel bowl.
