Return line ideas
OK someone point out any huge holes in my theory here.
This is the vapor return system which was originally plumped to the charcoal canister. I was originally planning on just tying in here for a return, but with the Y and size reduction I no longer think this is a good idea.
So Plan B.
There is a transfer pipe (for lack of a better term) that goes from the filler to the neck (metal pipe running across the sender.) Now I’m thinking of using a “T” here and returning fuel here. I’ll use a long rubber hose with a T until I confirm it works OK, then have a fitting welded into the metal line and put it back like this with addition of the fitting.
I’ll of course remove the vapor return piping and plug these with a couple HD vacuum caps and aviation sealer. (Of I suppose I could just loop a pice of hose between them.)
Plan C would be to put a return fitting near the sender, but it seems needless to put another hole in the tank to me.
I’m all ears.
See my sorta project thread for other musings:

Re: Return line ideas
No. Don't do a top fitting as it'll drive you nuts listening to the gas drain into the tank.
Drill a hole in the tank and install a female fitting and a long length of tubing to the bottom. Weld it to the back of the tank so it doesn't break off if you are ambitious. I did something similar on my diesel conversion. Used the newer 3/8" line for a feed and ran early 5/16" line for the return. Used two stock tubing pieces in the cab so they would look stock and just drilled a second hole through the floor for the return to go through.

Re: Return line ideas
OK, my tank is a bit different from that one, there is not as much flat area to install the bulkhead type return fitting, the best place would be approximately the same spot as the pickup on the opposite side of the sender, but that will interfere with the sender float. Due to the welding of the pickup, not enough truly flat space over there...
OH, and the sender is out, not nearly enough room for the bulkhead fitting... though if a guy had a welder and flare tool that could be made to work too.
Right now I’m unwilling to pull the tank and have a fitting installed so I’m going to go with plan B for the moment. It does have fairly loud exhaust on it....

Re: Return line ideas
Personally, I'd love to hear gas draining back into my tank. As it is right now, I see way too much going out my exhaust pipe!DuckRyder wrote:That is a good point I didn’t think of...Ranchero50 wrote:No. Don't do a top fitting as it'll drive you nuts listening to the gas drain into the tank.

Re: Return line ideas
Well I did manage to get the tank sealed up enough to at least greatly reduce the fuel smell in the cab.

Re: Return line ideas
I was getting gas smell around my sending unit once. The auto shop sold me a tube of non-hardening black Permatex, because it could hold up to gas over time.DuckRyder wrote:Well I did manage to get the tank sealed up enough to at least greatly reduce the fuel smell in the cab.

Well, it seems like it is at least fuel vapor tight...

Re: Return line ideas
Not the best looking but I’m pretty sure it will work OK.

Re: Return line ideas
This worked out plenty fine. Can’t even hear the fuel running back in...
