I just finished replacing all the return lines and caps now I want to replace the line that goes from the lift pump to the filter housing. I would like to use a flexible line and I am look for the parts to do it. what size and type fittings are used to get rid of the stock hard line? Also I want to replace the line from the tank to the lift pump bypassing the fuel tank selector as well as the return to the tank. for this what size and type of fittings are needed? can I re use the fittings that go to the tank now? what size line is needed?

 

why hard lines rarely give trouble. all can be replaced with fuel line from napa, hose clamps are hardly needed as all pressure is less than 4 lbs on all lines before the IP,,,most common air leaks are the fuel heater in the filterhead, and or bad or dirty check valves in lift pump from tank debris getting in the lift pump, do your self a favor and install at or near the tank a 100 micron prefilter to prevent this problem..
