Fuel pump question

[rat tuned]

joe,
did you look at the picture of the pump? i'm curious how you would rotate the pump? is the picture not what the actual part# looks like? it is part#6415748. i'm curious if anyone has actually used that pump. what would the actual fuel pressure be with the engine warmed up? how mant gph? i got the number out of the "how to hot rod big block chevies" it is an older publication. thanx again mike

I just looked up that part # 6415748 in a Chev. Power catalog---And it states---This high-capcity pump has a removable lower housing which can be rotated to position the inlet and outlet fittings as required by the chassis and engine installation--------------

I don't know if this helps,but I have the Stock AC #40727 Fuel Pump on my L-78 Chevelle,which resembles the one you show.
It recently tested out at 5-8&1/2 PSI @450-1000RPM.
Volume was 1 pint 30-45 sec. @ 700 RPM.

It's amazing how much thought and effort it takes just to decide what fuel pump i need to order!This is about as hard as ordering a cam!

That photo rat tuned showed does say it's rebuildable--so the housing should come apart---So check it out---With your 750 Holley--Rob's --Rick,s --or the one in the photo are plenty ---You're lookin for at least 4psi at wot ----IMO

Any of those AC pumps will be just fine for your application, DS...no need to spend the extra money for a monster pump for a mild application as it will only eat horsepower...

i have a day 2 type 69 ss 396 chevelle. i'm running a 10-1 454 with holly 750dp, 10" conv, xtreme274H cam, 4.10 gears. the fancy headers won't allow a bigger pump body(too close to header)with the stock replacement carter pump it feels like its nosing over at my shift point(5800-6000). you guys think the the #6415748 with a lightweight pushrod might help? also has stock 3/8" fuel line. thanx mike
