Fuel System: v8 carter fuel pump glass bowl

[1960Hawk]

hi,
going to throw on a new carby soon and refurbish the fuel pump with an ethanol kit.
I need a model number please, and does anyone know what is the psi output?

[r1lark]

The model number should be stamped into the edge of the mounting flange.

Sorry I can't help you with the output pressure.

[studediesel]

Fuel pressure should be 3 1/2 to 5 PSI.

The original pump would be a Carter m2573S

thanks, can order kit now

Qs...anyone

would this be sufficient for an edelbrock avs2 500cfm ?
was reading somewhere 6psi is the sweet spot.
the original carter 4barrels where smaller ?

Does the ethanol rebuild kit give it slightly more psi?

I do have an electric fuel pump installed, but only for priming.

Call Dave he is easy to talk with and knows all about those pumps...he has the parts and the knowledge....

That pressure is Fine, the Volume is more important though.
If operated above 4000 RPM often, a Carter Super Pump is recommended as on R1 and R2 Avantis.

thanks, good info for others searching

....so for your street driving / cruising and casual low performance street drag, it will be fine.

will using a larger fuel line from pump to carby help increase volume?

[1960Hawk]

forget the larger fuel line Q....
larger line = less psi
its just a run about street car and not worth stuffing around :0

Hi 60,

Welcome to the forum. Are you in South Africa or South America, or Australia?

Most Studebakers in the 50's and 60's ran 450 to 600cfm carbs. If you have a 2,500cfm you will drown the poor V8 and have very poor performance in my opinion. I had a 1955 V8 that had a Carter but I don't remember back to 1968 what the cfm was but with the overdrive the car ran great up to 120mph@4,500 rpm. That was pretty much the limit due to valve float above 4,500. The mid 60's performance V8's had strong valve springs that give you higher rpms.

My 57 Golden Hawk does not the supercharger hooked up so it is running a standard fuel pump. The GH pump is different in that is has a pressure line running from the blower to get more psi when the blower is engaged. The car runs great and from a start, with the 3 speed and overdrive and a 3.92 TT dif has not problem leaving other cars behind at a stop light start.

Best regards

hi sir....thank you.

I don't have twin 500 carbs
the 2 is from edelbrock AVS2.
swapping out the holley 600 for it

not going to play around too much with the motor, because it already goes like a little rocket :0

Bob-
Since 1960Hawk didn't answer your first question, I will. Adelaide is in the state of South Australia.

finally got a to start on updating the carby....

pump overhaul, ----glass bowl filter.

my kit came with a brass filter and different spring.
And that spring is perfect for holding the brass filter in the glass bowl.

Would the mesh by itself be better flow?
or just stick with the older type filter?
It is possible to use both filters with the old spring

Just be sure it all clears the steering.
