Fuel system

FYI, You could almost run a stock mechanical fuel pump with a Holley and get away with it. Dual inlet, and plenty of bowl volume.
Running a single inlet carb, with very limited bowl volume has unique needs that are different than a Holley.
If you never raced with a Qjet,AVS,THERMO Quad, ect, and or used a Data recorder, or a wide band O2, you may have a hard time believing this. Engine size, HP, car type will dictate what an engine likes. My brother has a 20 year old Comp 140 pump that came out of my car, in his 10.50 bracket car all day long without a problem. I have not experenced the same results.
Race on while we still have classes to race in.

Ran a Mallory Comp 140 pump and dead headed regulator for many years feeding my 700+HP 468 from the stock/unsumped gas tank without issue.
