60gph or 110gph fuel pump?

injectedEB · 06-13-2001, 11:09 AM

I can get a great deal on a Mallory inline pump for my SEFI conversion, I am just not sure if I want the 60FI or 110FI?? They are 60 and 110 gph units I believe at 60psi. BTW- 60 gph = 227 lph and 110 gph = 416 lph

I will be running a 306, TFS heads, TFS street intake, TFS stage 1 cam, roller rockers and lifters, 65mmTB, 73mm MAF, 24lb injectors, - main operating range is 1500-4500 rpm with occasional runs to ~6000rpm.

I need to order the pump today to get the deal - I know bigger is better, usually, but I am affraid the 110gph will be too big...

Unless you plan on running 150lb injectors and 30lbs of boost on that motor, go with the 60gph, that should be more than sufficient for your application. Most people run a 190lph with your combination which I think is only around 50gph.

thanks - that's what I thought, but needed some else's reality check too
