when you guys installed you webers what did you do to your fuel return line cause the weber doesnt have one and with out it the gastank will have no pressure? i think im gonna have to use a regulator with a return ? thanks so much

 

you can buy a fuel inlet fitting for your carb that has a return line on it.

 

if you use a holley red or similar (not holley blue), you DONT need a return. Dont waste your money

 

whats wrong with using a holley blue?

 

Holley blue is 14+ psi. thats too much pressure. A holley red with regular holley PFR will save you $$$ for at least a 12-Pack of beer. Also, if you enlarge the IDA's fuel bowl (im referring to knocking out the partition), you can run the fuel pressure to 4 psi wtih no problem of fuel starvatiion at high RPM.

 

using a mallory 140 and just picked up the fpr 4309 with return hope this works casue the only way to get fuel now is to blow air in the return line...
