Re: Gas tank vent questions

The pipe on the sender is fuel out (obviously). The two smaller ones, on either side of tank are vents. The larger one (beside the fuel filler) goes up to the top of the fill neck to vent air out (equalize pressure) when fueling.

If running fuel injection with a return you can use one of the vents for a return.
