The Stovebolt Site Forums The Shop Area General Truck Talk Fuel Tank Strap Attachment - Under Bed - 47 AD

Hi All,

I've taken a summer break and am ready to continue work on the fuel system.

The original tank straps need to be replaced, so new straps were ordered along with the new tank (leak checked just to be sure - no problems). Original straps were attached to the brackets with rivets, 2 per strap. I was planning on using a similar sized screw with a nylon nut, nut on top to avoid the tank.

- Have others replaced the straps, and if so, did you replace the fasteners with rivets, or screws?

- Will screws cause an interference with the tank?

- If rivets, any recommendation of size?

One more question: The tank mounting pads seem to be for use against the bracket. This mean the straps rest directly on the tank. Clearly this worked for many years, but seems like a place for fretting resulting in rust.

- Have others used anything to separate these? Like a piece of webbing?

Thanks in advance for the advice.

Bill

I have used 1/4" closed cell foam. It was pretty chewed up after 10 years though.

Mike,

Thank you.

Any other thoughts on strap attachment: Rivets vs. screws?

Thanks,

Bill

no, I did not remove mine from the frame. (59 Suburban and 58 2-ton)

I used button-head bolts - low profile, smooth surface.

For strap-to-tank insulation I used Model A frame webbing. Perfect size and shape, super durable, and can be purchased from any Model A parts house.

My panel has its tank under the bed. I didn't need to replace the steel straps, but I put thin re-inforced rubber strips between the steel straps and the tank.

between tank and metal straps - strips of heavy black vinyl

metal straps-to-brackets - rivets (largest diameter that fits the hole)
