My dual action fuel pump went out and I ordered a new one. While I am waiting for it to come in, I decided to rebuild my Holley 4160 carb and inspect the fuel line. To my surprise there was no fuel filter to be found in the fuel line anywhere. The only reference about the fuel filter in the shop manual was on T-Birds, the glass bowl type filter was located between the fuel pump and carb. I went to NAPA and bought 2 in-line fuel filters.

Should I install both - one between the tank and pump and the other between the pump and carb? Where in the line should I place the fuel filter between the tank and pump - closer to the tank or closer to the pump?

In the winter, I plan to replace the entire fuel line. Should I use 5/16 stainless tubing like the original or use 3/8 stainless tubing?

Any tips for installing the dual action fuel pump - looks to be a little tight in that area.

Thanks,
Danny
