fuel line question.
 

if i replace the fuel line from the tank to the lift pump with rubber fuel line does it have to be high pressure line?

High pressure, no. Just make sure that it won't collapse under suction.

Dave is correct...

Does not need to be high pressure,just needs to be a good quality hose that will not collapse under suction load.Either a good marine based fuel line or a fuel injection type hose would work very well as they would stand up to the elements very well......Andy

Make sure its diesel rated
