Hey All, I just wanted to say a big thanks to all on this site/thread on this important fix. I ended up having to replace my rotted well nuts with the bulkhead fittings just as specified here with no leaks afterward... what a huge relief! I also replaced the old rusted fuel level sender at the same time which gave me access to the bottom fitting with relative ease. I don’t think anyone mentioned it here, but with the fuel level sender out, you can actually take out the fuel drain hose, thread the an fitting and bulkhead to the hose with sealant, and then pass the pre-assembled hose/fitting down into the tank via the fuel level sender hole and back out the drain hole on the bottom with the bulkhead fitting already attached to it. You can then just pull on the hose from the inside of the set to snug up the bulkhead fitting on the inside of the tank. Made it insanely easy and I can’t see doing it any other way. I used a KUS USA 5.5” sender, 33-240 ohms with same bolt pattern and good for 24V. Thanks again to everyone with their input on this topic!
