okay im going from to carb and i got one of those spectre afpr and it turns the psi down but theres not return line on it will this still work or do i need to get a different one.
.o. heads 1.94int and 1.64 exh and edelbrock 650cfm carb and spreadbore intake with adapter.And full exhaust.

also what should i be running with lt1 cam 305 h

 

Get a different regulator, that has the return line. Your fuel pump won't last long running into that. It's made for a diaphragm-type electric pump, not a FI pump.

You need about 4-5 psi.

 

does anyone know where i can get one i aint got alot of money left so i need one that jus gets the job done dont have to be pretty jus works.
