Fixing leaks on plastic gas tank.

[NorthGaAire]

The PO installed a plastic gas tank.

I had to install a new pick up tube with new gaskets and new gaskets on the send unit plate.

I still get leaks around the two openings - between the plates and gasket.

What are my options other than buying new hardware?
Is there any sealer that I can trust to hold and stop the leaks?

Thanks.

Pretty sure the only source for these tanks is MTS. Here is their web site - http://www.mtscompany.com/J-truck.htm They could best tell you what to do to seal those openings. I'd give them a call and ask for advice.

You should be able to find a Fuel resistand adhesive at and parts store. Make sure the area is very clean before applying and let it dry over night before using.

I had a similar issue with my sending unit when I replaced it. My issue is that I was trying to use the flat cork gasket that came with the sending unit. The MTS tanks are designed to use an O-Ring on both openings. BJ's sells them. I was in quick need of one, so I measured and went to my local ace hardware. Finally found one with a large enough diameter, although it was a touch thicker. But solved the leak issue.

One word of caution as well. Watch the clearance between the frame crossmember and your forward mounting sending unit in the tank. The threaded post on the top of the sending unit may actually come in contact with that crossmember when the tank is fully installed. It was basically throwing all kind of weird readings for me on my gauge. So I lowered the tank enough to slide a small piece of cardboard in between. Solved that issue, and I plan to trim that post down the next time I drop the tank.

+ 1 on checking the crossmember interference with the sending unit location.

I did use 3M Structural Adhesive on both openings. My local parts store recommended it - sells it to several local small engine shops for plastic tank repair. So far so good.
