Maybe I can save the trouble of someone needing to get a photo of an original tank without the locking ring. Mine is a '66, not a '67 though.
My new tank:
My original (I believe, came with the Jeep) '66 V6 tank with return fitting and non-locking sender hole:
The sender itself:
No return line ?
Sorry that old tank isn't in the Jeep at the moment, the line is currently hooked to a rubber hose going to a Hawaiian Punch jug if that's what you mean?
As far as I know, the lower two pics are the stock '66 setup, and as found, there isn't a tank with the return fitting on the market. The radiator shop said they might be able to transfer that return fitting to the new tank much easier than they could have repaired the leaks on my old tank but I haven't taken it back up there for them to take a stab at it.
If you need a pic of the return line setup still in my Jeep I can grab one.
This is just inside the driver side door, the line nut is slide back so that the rubber hose could slip over the flare a good bit (not sure why I went that far though). There is a grommet/bushing there where it should normally pass through a small hole in the floor (rust monster made it grow), it felt solid but it might just be really dried out rubber. It then turns and runs towards the frame as the next pic shows.
You can see the clip holding it in place and the loom guarding it as it cuts over behind the frame, where I could not see it well from the angles I wanted to get tonight but it looks like it runs straight along the frame and comes out where the next pics show.
One of those looms is the wire, the other one is hidden behind the two in this pic. In the one below it's a little more clear, but they basically enter the engine compartment coming from different directions but at the same point. Couldn't get a great pic of it apparently.
The return, I think, is the narrower loom on the bottom, and they both switch to rubber at about the same point.
No problem. I seem to recall you having asked for any help on the return line routing a long time ago in fact. Had been meaning to get these pics. Can take some more when I feel like crawling on the floor or getting my hands dirtier in the engine bay.
Are your original lines steel or vinyl ?
Vinyl? Don't think I would even know what vinyl lines would look like, but I assume they're steel as they are some kind of metal for sure. Although given the age claiming them to be 'original' may be dubious. But definitely old.
My original lines went from pump over the engine as steel then rubber to vinyl
I don't think I saw any vinyl fuel line in the run anywhere, just the steel and rubber. And definitely not the over the engine run, that was a fairly long custom bent steel line that has been hard to find a matching replacement for. So maybe it wasn't stock after all, but someone's custom bending work. Really good custom work if so, the bend was tighter than most shadetree line bends I've seen.
I'd seen those pics but I had actually thought at a glance that they were steel lines, interesting. Nothing like that was on my setup.
The boys 70 had plastic lines and a return didn't have a tank though
Front to rear... Mine has steel lines on the motor, to rubber, to vinyl/plastic at the firewall. The vinyl runs under the Jeep to the tank and then to rubber again.
The new tank and sending unit before I installed it.
Sounds about what mine had
So this is what I came up with. It was a practice run :-( I'll explain in a bit. I drilled a hole in the sender where the return line is supposed to be.
Then I ran a 1/8" npt thread tap since the sending unit plate was thick
Then took a compression fitting for 1/4" tube and drilled thru so I can slide the line thru it
Put a bubble flare kinda on the end
So there you go
NOW for the bad news. While doing this I broke the float arm soooooo $49.99 later a new sending unit is on its way and I get to do it over. This time I want to try to get a little tighter bend on the tube and get it a bit smaller and lower.
Oh yeah, did I mention the big hole in the tank I have to weld
