 |

Hello Gaggle:
I have been fighting leaking fuel tans for a while. The tanks are aluminum and sealed with PRO SEAL or the equivalent.
Since my engine likes both AvGas and MoGas and MoGas has ethanol I would like a sealant that can stand up to both.
Stop - I know about the trick of removing the ethanol from MoGas but that is only about 90% effective.
I would like to run straight MoGas.
Would anyone out there have any experience in this area?
Thank you for the assistance.

How about this ACS part number 09-02566 . I have used it on fibreglass BSA tanks.

Dave, I'm curious that you mentioned that removing ethanol from mogas is only 90% effective. Have you tried it? I am experimenting with removing ethanol from mogas and it works fine so far in my Kitfox/912. If there is a bit of ethanol left in my gas it has not caused any problems. There is little information out there about washing gas.

Kreem Weiss is a great tank coating. The entire 1500+ fleet of Flight Design CT's has it's tanks coated with Kreem and most of us use ethanol fuels. 325 of them here in the states. Never an ethanol issue. Some in Europe and South America use up to 18%-23% ethanol and never have any issues. It is pretty much impervious to anything, that's why so many people that coat tanks use it professionally.

Dave,
What is the root cause of your aluminum tanks leaking? How old are the tanks? Are they leaking at fabricated joints? How long have you had this problem? The reason I ask is, I have aluminum wing tanks in my Allegro 2000 and have not had any problem with leaks since the first flight in 2007. I now have almost 500 hours on the engine and I use 93 octane (ethanol free) fuel as well as 87 octane (10% ethanol). Is your problem the fuel or poor fabrication of the tanks?

Hi Roger:
I have tried this sealant. It worked GREAT on a stationary tank. But FAILED quickly when used on a flexible aluminum (aviation) tank and on fiberglass tanks. The stuff dries almost stiff, not really flexible.
What might you know about:

Pete:
You are correct.
Yes, I have tried it for two years. It does work pretty well, but if you religiously check your gas on a pre-flight you will find water in it.

Only on motorcycle tanks. The fibreglass used on BSA tanks of the sixties doesn't stand up well at all with the crap we call gas these days. This stuff seems pretty much able to stand up to it, which is what they claim for it. It's foul to work with but once hardened seems to stand up well.

Hugh:
It is I, Barry that posted the question.
The tanks are quite a few years old... About 30 years old. And they are sealed with PRC, as I mentioned. I resealed them with PRC put coatings on top of the PRC. But it still leaks. WAY too much work and expense to disassemble the tanks and start from the beginning.

Barry,
You got that right. I do check. I was thinking of "aging" my washed gas in a clean empty glass carboy for a week or so then siphoning the gas off to use.

HI, I think you might be confusing me with FlyDive. I have no aluminum tanks. I am worried a little about my fibreglass Kitfox tanks but so far no problems. I have used this product for vintage BSA fibreglass and it appears to hold up, but I don't think we have alcohol in our gas here in the Maritimes. I sold off all the old bikes, but all my experience with this has been ok.

Barry,
I have aluminum fuel tanks in my Zenith 701 (4) 11.5 gallon tanks. They were welded at the factory and I haven't had a
problem with leaks..... yet.
Since you have been having this problem for awhile with leaking tanks, maybe a more permanent fix should be made.
I'm sure it would be alot of work to get the tanks out, and they are full of old sealant that would make this impossible.
My friend has been fixing tabs and threads on his harley engine for awhile
now with great sucess. Watch this video and please post any comments.

I would love to do that....
Problem is the TANK is the WING. It is know as a Wet Wing.
And the material is only 0.020" thick. And there is no access to the inside of the wing/tank for ANY type of welding.
Some problems are really problems 
The main problem is that the sealing compound's chemistry has changed due to the EPA. It is know to be cancer causing in California Rats. WHO CARES!
I'm not a California Rat and I don't plan on eating it!
I just want a gas tank that does not leak.

When I did my kitfox 2 wing, I took off the wing and just rolled the wing around up down side to side to get all the KBS coating evenly inside the tank . I have a 13.5 gallon wing tank. I did the whole process they sell ya work for me very strong stuff

I would love to do that....
Problem is the TANK is the WING. It is know as a Wet Wing.
And the material is only 0.020" thick. And there is no access to the inside of the wing/tank for ANY type of welding.
Some problems are really problems
The main problem is that the sealing compound's chemistry has changed due to the EPA. It is know to be cancer causing in California Rats. WHO CARES!
I'm not a California Rat and I don't plan on eating it!
I just want a gas tank that does not leak.

Barry,
I have aluminum fuel tanks in my Zenith 701 (4) 11.5 gallon tanks. They were welded at the factory and I haven't had a
problem with leaks..... yet.
Since you have been having this problem for awhile with leaking tanks, maybe a more permanent fix should be made.
I'm sure it would be alot of work to get the tanks out, and they are full of old sealant that would make this impossible.
My friend has been fixing tabs and threads on his harley engine for awhile
now with great sucess. Watch this video and please post any comments.

I have been fighting leaking fuel tans for a while. The tanks are aluminum
and sealed with PRO SEAL or the equivalent.
Since my engine likes both AvGas and MoGas and MoGas has ethanol I would
like a sealant that can stand up to both.
Stop - I know about the trick of removing the ethanol from MoGas but that is
only about 90% effective.
I would like to run straight MoGas.
Would anyone out there have any experience in this area?
Thank you for the assistance.
Barry
