POR 15 or other fuel tank restoration products

[Bill Howell]

I know these products have been around for years, however, have any of you guys actually used them. I am looking for a fuel tank cleaner/restoration product to neutralize the rust inside the tank without fear down the road of clogged injectors..etc.

A buddy of mine and I used it on an old Bultaco gas tank a few years ago. No problems as of yet. Don't know that I trust it for efi though especially on a large tank. If you leave a holiday in there somewhere you're hosed.

Might pay to purge it, split it, blast it clean, then re-weld and galvanize it.

...and you owe me a phone call pal.

Most radiator shops can use a product that re-seals the inside of the tank and holds up. Its usually not expensive either, might be worth calling a shop or two.

I know Kreem is crap. Most of those have a 2-3 step process. First they have an acid ectch. Pretty touchy to get done right, and done wrong it's a mess.

I have an old tank on my car I had to clean because I was catching particles in my prefilter. I have been putting STA-BIL 360 protection in it at every fill up and it seems to have helped out a lot. Fairly inexpensive but probably not a good long term solution.

Can't speak to POR-15's resistance to fuel but I have used it on frame rails and it does a very good job.

I hate Por-15..

Not sure on the gas tank sealant,, only used it one time, tank rusted out between the Por-15 and the steel..

I would look into caswell for tank sealant..

All on motorcycle tanks, but, I have personally used por15 been fine for several years, used redkote it was fine for least a decade sold the bike, had a radiator shop tank and coat one that has been fine for a solid decade also, its still in the stable, thought about how to handle the tank in my 69 bird until I priced new tanks at $130 for a zinc coated tank and $300 for stainless I am going to buy a new one.
Most coatings run around $75 then you have your labor to boot.

Thanks guys. This was for a friend that is working on a motorcycle so I will let him know.

Bill the tank in my Camaro was restored with the Eastwood gas tank coating. I got it from a friend several years ago and stored it under my house. I looked in it when I swapped it into my car this past year and noticed the coating is holding up just fine with no signs of separation or flaking. It was done about 6-8 years ago. It's a bright white coating and is epoxy based if I remember correctly.

I used the gas tank sealer kit from KBS....nice product. Used to seal my tank last spring.

I totally disagree. I sealed a tank with Kreem 30 odd years ago and it is still in use today. The only word of caution is to use it in a well ventilated area.
