Fuel Level Sensor leaking

Recently installed a new fule level sensor. After filling up ths weekend, gas started coming out the sensor cover through the screws. Leaked until gas level was below cover. I've tighten them to the point I may have stripped a screw. Still leaks.

Any suggestions?

There are small washers that should be on each screw, if you've stripped out the threads in the tank, you can go to the next size self tapping screws. ~Alan

Also, did you replace the gasket? If not, buy this:

and....if you are actually getting leakage around your screws(you shouldn't), try installing the screws "wet"(smeared with sealant).

Washers, what washers? No washers came with it and I don't recall if the original had them. I replaced the rubber gasket. Are they just standard washers? And, what sealant would hold up to gas?

Sealing screws, both pan-hd + csk:

(I believe there are generics, but avoid the foreign crap)

Scott, Great Find! I bet these would work great on the oil strainer cover on the sump! http://apmhexseal.com/self-sealing_nuts.aspx

These "Hexseals" have been around awhile-usually in the form of a Mil-spec p/n. These people make good stuff and, while not the cheapest, are recommended for "fuel-related" applications. Read the web-site's "applications/notes" for info. Available thru high-end racing stores, aircraft suppliers, specialty hdwre. Fyi: seal-rivets are out there as well.
Also for fuel-related racing parts:

(Note to D. Bradley: fuel fillers here too)

I would suggest using only dry type gaskets. If memory serves (it more frequently doesn't lately) I used a silicone based adhesive sealer on a boat gas tank once. The gas pretty much turned the silicone into jelly and proceeded to plug up the entire fuel hose. The in-lilne gas filter saved the engine.

Always check applications/compatibility!
