Yesterday while installing a new pre-bent fuel line in the Dart, the tube protruding from sending unit turned while removing old rubber line coupler. After filling tank it now has a slow but persistent leak at the sending unit’s fuel tube.

Two possible fixes come to mind once tank is low on fuel: repair with epoxy stick that sets in five minutes; or solder joint where tube and face plate of sending mate.

Any thoughts on this predicament?

Either way is an acceptable way, but one would argue that the epoxy is a fix it for now until i can fix it right type of thing... There is another post here dealing with what epoxy will work for gas tanks/lines. 35 years ago, when I was a LOT younger, dumber, and broker, I patched a small hole in the bottom of my mustangs fuel tank with JB Weld, until I could "do it right or replace the tank" but guess what? Never happened and still leak free. ( i still own the car)

I went with JB Weld stick method. Cleaned adjacent metal, degreased the area, mushed up a wee bit of JB Weld, and formed a collar around pipe and face of sending unit. It is a thing of beauty…

Time will tell at the next fill-up if this repair was successful.

you could always replace pickup/sending unit

I replaced the one on my 67 dart gt, it had sat for 8 years before I got it, and gave me no end of fuel problems. That, the tank, the line, and filter all got replaced and I rerebuilt the carb. The whole thing isn't too bad at rockauto if the jb weld doesn't hold, but since its done, may as well see how it does. I got an extra seal and lock ring for the 67 tank, bought the tank and sending unit and both came with that, holler if you need an extra one of those.

The lock ring and sending unit to tank connection wasn’t leaking; it is the fuel tube protruding from the sending unit that was weeping. While removing the old ground strap and flexible fuel line coupling, I torqued the tube a little. It is just crimped into the sending unit’s face plate, and that connection is where the leak was.

I’ll keep an eye on it, but I think it is sealed up now.

Yeah, my old one did that same thing, just saying if the gasket goes bad too, I've got a spare.

New to the forums but I found a replacement sending unit for 35 bucks at summit racing a couple weeks ago for my 66 valiant, I am assuming they are the same part. Figured the price was right for new when replacing my tank.
Good luck and hope the jb weld holds and saves you some money.

I have already had the pleasure of removing and reinstalling fuel tank when I replaced bottom sheet metal in spare tire well. It’s a job not on my top 50 list to do solo. So any time I don’t have to drop that thing, the happier I am.

The fuel pickup tube was soldered to the sending unit plate. It's been awhile since I had to do the sender, but I seem to recall that I was able to sneak it out past the rear axle housing with the tank still in place.

much easier if you drain tank

Can you disconnect the shackles and droop the rear?


Hopefully the OP used fuel injection line and clamps to deal with the moonshine diluted fuel.

That is more work than dropping the tank, and is not in the top 60 most enjoyable tasks.

I inspected the old flexible fuel line once removed, and it had not degraded. I replaced the two flexible couplings with the latest FI line, and used correct clamps.

I haven’t filled the tank yet, because I have the manifold off waiting for a “Good Gasketâ€￾ to arrive. I think the epoxy patch will fix the problem.
