I replaced my lines from the engine to the pump filter included and the evap line with a kit from Gas Tank Renu more than a year and 10,000 miles ago when the fuel pump quit and I had to replace it. My truck is a 1998 K1500 extended cab. I was able to remove the original line set completely intact, due to the rust/corrosion basically welding the connections together, with a multitude of pinholes being exposed in the removal process. The kit came with everything and all I had to trim was the connections to the filter which gave instructions and fittings to adjust for truck length. These kits from this supplier are backed up by their original application for fleet municipalities police and maintenance trucks in highly corrosive environments. And they look new today as they did when installed. The problem I saw with my original line set was the connections between the flex lines and the tubes were corroding away at both the front and rear, plus the steel to steel in the middle.
I have also used their kit for the 90 K1500 on my Chevy/YJ Jeep using
TBI 4.3/700r4/NP231 for drivetrain with a 90 suburban fuel pump.
