Cleaning and sealing fuel tank

[rscottm]

Has anyone done this job and what products would you recommend? I read a review on Eastwoods system and it was not favorable at all regarding the sealer. I found another kit offered by POR I think. Both of these kits seem to run around $55. Does anyone know of less expensive methods that work?

Check out the Kreem kit offered through motorcycle shops. I've used it many times on bike tanks and never had a problem. Just make sure to do the clean and etch steps to the letter. Good luck.

What does the inside of the tank look like? If rust is minimal, I'd just poke a pressure washer in the filler hole and blast the thing out. Let drain, dry. Rinse with acetone, let drain, dry. Then reinstall (perhaps after repainting the outside).

If you've got extensive rust, then you'll need to eat it out and seal your tank. Just be aware of the anatomy of your tank. Mine has a large pickup screen in the bottom, which my radiator guy (who has rebuilt Z tanks) says will be eaten away by acids. He also says that a sealant like POR15 will clog a pickup screen. Of course if its got large holes in it from the acid wash, there's nothing to clog. If you pursue that route, just be sure to put a pre-filter inline before your fuel pump.

I second what Fastwoman says above^^^. If the rust and sediment is extensive like mine was, you will have a hard time getting it all out and you will forever fight clogged pickups and filters. IMHO, bite the bullet and have a radiator shop blast it and seal it for you. Money well spent.

5150 is correct. Check with your local radiator shop about "boiling" your tank out.
