I am offering highly durable fluorosilicone o-ring kits for your various fuel caps. Please PM me or respond to this thread with your interest to include type and quantity. I will PM you for shipping and to provide you with payment information.

These fluorosilicone o-rings offer superior durability to help your fuel caps keep the fuel in and to keep water out compared to your less superior rubber nitrate o-rings, which have to be replaced frequently. I will be offering kits for Shaw 531/431 caps, Shaw 416 caps, and Gabb caps. Prices and contents are below. These prices also include shipping. CSOBeech has a great writeup on these o-rings at http://www.csobeech.com/fuel-caps.html. Installation is pretty straight forward but there is additional guidance on CSOBeech.

I installed all new fluorosilicone o-rings on my four fuel tanks on my M35 Bonanza. They were absolutely needed. Not only were the old rubber nitrate breaking down on the big o-rings, the little ones were in poor shape too. The kit includes both the outer and the often overlooked inner plunger ring. If either are not working correctly, they can let water into your fuel tanks. Each kit also includes the correct cotter pins for the castle nut on the bottom of your fuel caps.

- Shaw 431/531 fuel cap kit - $12.00 each
o M25988/1-338 – big o-ring
o M25988/1-010 – small o-ring
o MS24665-298 – cotter pin

- Shaw 416/516 fuel cap kit - $12.00 each
o M25988/1-232 – big o-ring
o M25988/3-010 – small o-ring
o MS24665-132 – cotter pin

- Gabb fuel cap kit - $14.00 each
o M25988/1-339 – big o-ring
o M25988/1-110 – small o-ring
o MS24665-298 – cotter pin

I am interested. I need to find out what type of fuel caps I have on my 73 Cherokee Six but 3 tanks always have water after a good rain. I’ll message you with some pictures of the fuel caps!

Send me the photos of your fuel caps to [email protected]. I’m not sure if Cherokee Sixes have flush mounted fuel caps.

Mine doesn’t. I didn’t realize it was only flush mount.
