I use the Fram cannister type like 35Window uses. In the 57 I have it mounted in the engine compartment on the fender just before the fuel distribution block (to the 3 carbs). The 57 has a SW electric fuel pump mounted in the rear under the rear bumper. On the 34, I have one mounted on the frame just after the Holley electric fuel pump which is mounted on the frame behind the real wheel. Also have a standard in line metal one between the fuel tank and the pump.

The cannister type is easy to change and the replacement filters are reasonable at about $6.
