Thread: Fuel gauge repair

Gotta be careful, Gasoline Reistant is not exactly gasoline proof. I've had luck with this one Seal-All Contact Adhesive and Sealant 380112: Search no more for the best Threadlockers at Advance Auto Parts

Just out of curiosity I checked out a replacement sending unit.. TELEFLEX Universal Electric Fuel Gauge & Sending Unit Kit | West Marine

a bit more work, but probably more piece of mind.

I'm thinking they have a portable tank with the fuel level gauge built into the cap..........

If so............. If the float cage and cap are plastic I would try and plastic weld them back together........If one or the other is metal I would look on ebay or amazon for a replacement cap.

Thanks. I think we'll take a look at the auto parts place and the local Sylvan boat dealer to see what they say. The cap is plastic, but the float assembly is metal, so we have to bond steel to plastic. No luck on finding a replacement from Bass Pro. Tracker doesn't make this model boat anymore and there's no telling what the exact model tank this is. Right now, we're doing the old, open the cap and see what's left.

Can you post a picture of the pieces............That might help us come up with a idea for a fix. atleast maybe a temp fix to get you by until you locate one.

Napa auto can get almost anything, but they gonna have to have model numbers or something to go on.........Maybe someone else can say if all modern portable fuel tanks have the same diameter hole and threads for the cap.

I think the 3M 5200 is gas and oil resistant, but better get it right the 1st time, no do-overs.

Okay, clarification - This is NOT a portable tank, If it was, we would just go to Wally World and buy a new one. This is a (we think) Moeller Marine model F090011 Permanent poly gas tank, 9 gallons. The float assembly is 15 inches long, and so far, I haven't been able to find a replacement . It is similar to one sold by Gander Mt. for Arctic Cat.
I can post a pix from OneDrive if I can find a link , but I have fits on this website.

I've owned commercial lawn mowers, that had poly gas tanks with clear plastic cap/fuel gauges and a plastic marshmellow shaped float on a metal slide is what I recall. You might check a small engine repair shop to see if they are available, or if all else fails make it a habit to peek in the tank!

Did you remove the fuel sending unit from the plastic tank top and now trying to secure it back and seal the space between the fuel sending unit flange and the poly tank? That is how I comprehended your question. If this is indeed the case, you want to source a new rubberized gasket to fit between the metal FSU and the poly tank. Fuel senders usually only come in a handful of sizes and are a common bolt pattern so they should be available for very little cost at your local marine dealer. Silicone-based gasket makers are a no-no as silicone degrades over time in the presence of gasoline and you run the risk of having fuel in the bilge or water in your fuel.
