Well, I'm going to be putting fuel injection in my truck. I was wondering what you guys have for ideas for hooking the return. I have a stock rear tank which I am not replacing. I will probably put a 38 gallon in down the road, but the tank is still good and clean so Ill just use what I got for now.

Let me hear some idea, thanks for your input.

 

'Could drill and weld a directional tube (like an ell) to the metal filler neck.

Or drill the sender's top and weld a return tube.

IIRC some tanks have a drain plug? Could use that for a return line & fitting.

.

 

If your tank is one for evaporative emissions, you already have a connection. You could use the 5/16" line that runs along the passenger frame rail back to the tank. You would have to "gut" the check valve that's on the top of the tank.

 

Should also add, that if I can get away with not dropping the tank would be a huge plus.

I like the filler neck idea.

 

I dont know if my truck has this or not. I actually used the evap line on my cutlass when I put the EZ-EFI on it. Worked great. After I found out the hard way to gut the check valve. Didnt know why my fuel pressure was so high until I dropped the tank and saw that on the sender.

I might just buy an Evap Sender, gut it and put it in if mine doesnt have the evap sender.

 

I dont know if they sell evap senders anymore. Bill or mike might could find one. I could never find one when I went to replace the one in my truck. Here's the link to what I did instead, it's toward the end of the thread https://www.ford-trucks.com/forums/1445093-lmc-tank-and-sending-unit-reviews.htm
You can check for ev/em by looking for a charcoal canister under the hood of your truck towards the bottom of the engine compartment. Should be a metal fuel line going to it and a vent hose coming off.

 

I put a tee into the filler neck vent hose and hooked a return line up there. Not the cleanest of looks, but it was easy to get to and there is enough hardware to find at a decent hardware store to go from the approximate 1" diameter of the vent hose down to a 3/8" or 5/16" fuel line.
