gas tank for blazer - The 1947 - Present Chevrolet & GMC Truck Message Board Network

gdavis · 06-15-2013, 02:10 PM

I bought a gas tank that fits a blazer and I am installing it in a 68 chev short wheel base steep side C10. The tank came in and with it was the sending unit and two rubber o rings. My question is: Which O-ring do I use? The one with the tab or without the tab. Since I'm dealing with gas I want to get a good fit and no leaks. What is the correct way to install the oil ring? Is there a lub that is used on the oil rings also? Gdavis

Might be simple but do the 0-rings sandwich the sending unit?

tank - o-ring - sending unit - o-ring - lock ring?

That might be the case. I really don't know. I thought that someone here has installed the sending unit on a poly tank.

I just dropped my oem tank, and it had the o-ring with the tab on it

Thanks a lot for the informaton on the o-ring. But, I need a three hole bracket that attached to the tank. Tank number 2042 the previous owner had altered it and now it is distroyed. So the short story is. I have to get another one. I contacted the builder of the tank this moring. I hope they can ship me another one.

How do you plan to attach the filler neck to new tank. Just curious because mine leaks there. Someone previously did something incorrect so I need to re do this.
