Hello folks, New to the site here. I'm having an Issue With my 96 12 valve sucking air into the fuel system. The threads from other members have been helpfull and I'm gonna replace all my lines with diesel rated rubber. My question is, I've seen mention of a " Drew Straw" and I'd like a little input on sending unit vs. Draw Straw, also installation info, Do I have to drill a hole in my tank, or does it install in the old sending unit? My steel lines where they go through the sending unit are very rusty, and I only plan on removing the box off my truck once. ( I know things don't always go as planned) but that is the plan. So I either want to replace the unit now or Install tha Draw Straw. Any info you have would be greatly aprieciated.

 

The Draw Straw I you dont have to drill the tank. It also includes return line connections to put the returned fuel back into the module.
