Gents,

What's the difference between a 3 line gas and a 3 line diesel sending unit?

I'm converting my truck to a duramax, so I just want to make sure I choose the right one.

Also on a two line, is it supply and vent, or supply and return?

I'll need a 3 line for the drivers side(supply/vent/return), and a two line for the passenger(supply/vent).

Thanks!
