Gasoila Thread Sealant for Ethanol E10 & E85 Applications – Non-Hardening, Non-Toxic, Opaque Dark Green Paste – USA-Made, 1 Pint – Ideal for Pipe Threads, Motors, Fuel Lines & More – Brush in Cap

Worked great to seal up the fittings on my electeic fuel pump.

Worked great on fuel fittings on a Holley fuel regulator

Got the fast. Just what I wanted!

easy to apply and seals perfectly. I used on two different gas tanks without any problem.

Our company produces the only DOT approved mobile gas station in US. We have tried every known sealant available. We even tested high end aerospace grade sealants. Even Hylomar Blue dissolves in ethanol based gasoline. Nothing works as well as Gasoila. But you must let it set at least 24 hrs. Ethanol in fuel is in itself a crazy endeavor. Forget the concept of turning food into fuel, the cost of putting a hygroscopic low energy liquid into non food based petroleum that destroys the equipment and engines running it makes an engineering nightmare for all. Gasoia E-Seal works against the nightmare of ethanol. Use it and move on. We wish we had.

My 09 BMW R1200RT with a polyolefin gas tank has the issue with cracking / leaking flanges around the fuel tank quick disconnect lines. I had already used the Beemer Boneyard clamps to prevent the hoop-stress cracks for years before BMW issued their own Walmart-version recall fix. When I decided to replace the nylon quick disconnects (that also crack) with stainless versions from Beemer Boneyard, I upgraded their version of generic Gasoila (which leaked a bit when I installed their earlier clamps) to this version because in the midwest USA we have only E10 Gasoline. It hasn't leaked a single drop since repairs, even after riding it hard and putting it away wet.

That it is a product that works perfectly with fasoline leaks in line firtung

This is the stuff you want to seal petcocks on a motorcycle. Non-hardening, and provides an excellent seal that prevents leaking. Messy, and gets everywhere, so be careful when you're applying.
