I’m in the middle of converting my old gas 5.7 fuel system for my 6BT swap and had a few questions. Filler neck, hoses, cap, etc. are all original gas components. The tank is super clean inside and I’ve replaced the in-tank pump with a length of submersible fuel hose. Original supply and return lines on the chassis have been cleaned and adapted to 6BT lift pump and return hard line.
- What to do with the evap/vent outlet on the tank? Just cap it off?
- What to do with the two in-tank wires for the deleted pump?
- My 6BT has a fresh lift pump, IP, and injectors and I’m wanting some reassurance that a 1998 gmt400 gas tank won’t create any problems when used for diesel. Internal coatings or anything like that?
