OK, I replacing a fuel cell with a stock fuel tank on a 914 that's got Webers. The stock tank has 2 ports at the bottom, one for feeding the engine and the other is a return. My understanding is that the return is not necessary for carbed engines..So, my question is how do I seal up this extra port on the bottom of the fuel tank? TIA..

It all depends on what type of fuel pump and pressure regulation system you are using. If you are using a high pressure FI fuel pump with a bypass type fuel pressure regulator, you definitely need the return line.
If you are using a low pressure fuel pump for a carburetted engine, the return line is not not needed unless you are using a bypass type fuel pressure regulator. |
