Does anyone have an idea of how many Gallons per Hour this pump will produce? I want to use one with my Carbed 420HP engine but I am afraid that the voulume will not be sufficient.

 

it wont be....the *performance* in tank pump that flows a whopping 255 liters per hour will still struggle with that...it pump 67 Gallons per hour...i think the stockers pump something like 50 gallons per hour.

id upgrade.....

few ways to go about it.....the right way....dropping the tank and pulling the pump out and putting an external electric on it

OR

the not so right way, leave the pump in the tank and try pulling the fuel thru the pump.

you might wanna look into something along the lines of a holley Blue ...110 gph.... you can get em on ebay rebuilt for like 60 shipped.
