Hello, I don't know if anyone has a solution for this but I'll ask anyway.
My truck has the dual tank option, and the fuel pump in the front/midship tank broke. So I disconnected the tank and removed it. I left the fuel line fittings that usually attach to the gas tank hanging. So I went to start the truck this morning and it won't start. It sounds like it's not getting enough gas. About a cup of gas pours out of the fuel line fittings every time as well.

So the fuel being pumped from the rear tank is coming out of the fittings that are supposed to be attached to the front tank. I have tried sliding another hose over the fuel line fitting and and a plug on the other side, and then putting two hose clamps on, but gas still pours out, and it still doesn't start.

The only way I think this could be happening is the gas from the back tank is going through the fuel line but since the two fuel line fittings aren't connected, that is the easiest route for the gas to go? I still don't really understand how it worked when the gas tank was still there. Anyways, if anyone has a solution or has seen this problem before, any help would be appreciated.

 

there is a check valve inside the fuel pump of the front tank you removed, without that its just sending fuel unabashedly to your lines that are disconnected. you can cut them and plug them, its not easy to plug them with the quick connects unless you cut the old "stems" of the old sending unit, insert them into the disconnects, and then cap/plug those.


as far as your no start, its probably not building pressure in the rail because of those leaks.


why not just fix the front sending unit? in all reality its very nice to have 2 functioning fuel pumps, so you don't get stranded when one dies.

 

Sorry for the late response. I decided to just spend the couple hundred bucks and order a new tank and fuel pump. Hopefully having everything plugged back in will fix the problem. Thanks for the reply.

 

That's the best solution.
