Any advise is most welcome. I tried for 2 hours and still don't have it installed.

Where are you trying to install it? Stock location behind seat or under bed blzer style tank?

purple gas · 07-02-2005, 10:30 AM

If your talking the stock one. I think I had the tank out, put the rubber gromet thing in the cab hole. Then from the pass door sort of aimed the filler neck through the gromet. Kind of awkward but it wasn't too bad. I had an old but in good shape rubber part, so it was a little " dry" and it slid ok while still being tight. A new rubber part that was "sticky" might be a lot harder. If your not talkin stock tank please disregard this entire message.

lube grommet with soapy water

Blue4x4 · 07-02-2005, 07:33 PM

It is the stock filler neck. The glass people who were installing the winshield let me use there spray silcone. I started at the top and when I got to the bottom, there just wasn't any room to push the gasket in. I might trying loosening the tank and going from there.

Ouch! The positive side of things is you get to clean behind and below the gas tank. Blazer tank, rear mount, hmmm!

It sounds like you have a 71/72' tank (2") and are trying to install a 67-70' gromet (1.5"). Double check that first.

4x4Poet · 07-03-2005, 03:00 AM

I just pulled the tank on a '72 K20 pickup I just...,er, picked up. Removing the seat was more difficult than removing the tank. My impact wrench made quick work of the tanks bolts. From underneath, I first wire brushed the threads and sprayed on penetrating fluid. Pulled the little hose at the sender first and the sender harness. I siphoned out most of the fuel first, too. The tanks is unwieldy. Significant fuel weight makes things difficult.

With the tank out, I can more easily guide the neck thru the grommet. I have silicone, as well. I also removed six inches of mud from the cab corners. No worries, it's a clunker.

Im missing something. I pushed the old one in, and cut it off. I lubed up the new one and slid it on. I worked the filler neck grommet on by hand. Fits good.

You obviously have skills. As for the rest of us.....

Harold Shepard · 07-04-2005, 03:11 PM

As stated before, use some type of liquid hand soap and be patient. Put the gasket in first and then lube the neck and the inside of the gasket, this is a two person job , one to persuade the tank through and one to hold the gasket so that it does not slip out. This will work but do not get in a hurry.

silicone dielectric grease does wonders. I learned this doing an oil cooler on a powerstroke.

4x4Poet · 07-06-2005, 06:28 AM

You're so right, 68C15. I've got a little tube of silicone. Works wonders on any effort to install rubber hoses. Only takes a tiny dab or two the size of a bb to ease sliding on a radiator hose. Silicone takes heat well and is harmless to rubber, too.
