Fuel tank and pump, electrolysis on tank? New pump?

Those fuel lines connections can be a whore...they'll wanna spin the line. Spray the fuck out of them with WD-40 24 hours in advance...and use the proper line wrenches. If it wants to spin the line spray it with WD-40 and wait. This ain't your DD so take your time.

I  used the cheapass fuel filters from the local parts store and had zero issues with them...and I swapped a new pump and filter in every spring before the race season fired up.
