The Stovebolt Site Forums The Shop Area Paint and Body Shop Replace fuel filler hose / grommet?

Can anyone tell me whether it's possible to replace the fuel filler grommet ('64) with the fuel tank still in place?
- or is the grommet such a snug fit into the body that it the tank must be removed first and the filler neck pushed back thru from inside after the grommet is replaced?

My grommet is in a bad state and the truck is being repainted, but I don't much want to disturb the tank at present

Advice welcomed, thanks Limey

It's been awhile since I did mine but I think my tank was in place. I think I removed the spout which is connected to the tank via short rubber hoses and clamps then replaced the grommet and then replaced the spout. I bought two or three grommets before I found a good one. Steele Rubber makes the best I could find.

Put it in a bowl of HOT water for ten minutes or so, it will help a LOT to get it in. But removing the filler neck is needed anyway you look at it.

OK thanks Guys. I'll need to look more closely as I thought the filler neck looked like it was a solid metal tube as part of the tank - but I guess there must be a rubber connector somewhere.

The tank has a short piece of filler tube comming from the tank. The you have a short piece of hose that is clamped around the filler comming from the tank and the filler that protrudes through the side of your cab. Move your seat forward and use a screw driver loosen the upper clamp and slowly pull the upper filler tube from the cab. Sometimes you will need to grease it or lubricate it well. Carefully use a utility knife to cut the old filler tube grommet so you can remove it.

After it's gone clean up the hole.You might want to prime it to protect it some more. Fit your new grommet in place, make sure you set it the correct way. Lubricate the inside with a non-attacing oil (cooking oil) and carefully push/slide the old filler neck on place (if it's a good grommet this will need a bit of muscle it's supposed to be tight), and re tighten clamp.

That's all there is to it.

thanks Jake I'll get to it

Try to buy a GM grommet, the reproductions start oozing down the side of the truck in a few days. Brian

Got one coming from Chevy Duty, so will have to wait & see the quality.
As I'm in England any part at all is a good part!

Hey Limey, should I use Armor-All on the leather petcock gasket of my '29 Brough-Superior ?

No, not serious.

Is your 'bolt a right hand drive?

Looking at this more closely I find the rubber filler hose has a split (which explains the gas smell when you fill up!) Access to the tube looks very bad.....

Any advice on replacing the rubber hose (on a '64)? Getting it off should not be a problem but is it possible to fit the hose onto the tank without removing the tank?? Any tips?

Thanks Guys, Limey

PS Jim Bow its a left hand drive - came in from San Diego last year and its full of rust!

I did my 65 a few years ago.You CAN loosen the clamps if you stand on your head. Be very careful of the gas cap flange. Mine was plastic and I cracked it with my slip-joints while "helping" the hose out.lol Tom

The filler neck (plastic or steel) and the grommet can be replaced without removing the tank. It is tricky, cumbersome and can be a bit frustrating, buy if you follow the proper sequence of loosening the two hose clamps on the rubber hose connecting the tank neck to the filler neck. I left the cap on the filler neck in order to get a good grip and twisted the filler neck out with the cap attached. Now cut out the old filler neck grommet. The rubber hose will now slide out the hole in the cab.

Replacing these parts requires the sequence to change a bit. Start by inserting the rubber hose with the two hose clamps. Tighten the hose clamp at the tank neck. Leave the other loose until the filler neck is installed and set at the proper clearance. Now lub and install the filler neck grommet. Make sure it is properly seated and indexed with the offset in the opening relative to the offset in the grommet. Now insert the filler neck through the grommet into the rubber hose. Press the filler neck into the hose to the proper depth to allow the cap to be installed and leave a minimun amount of filler neck exposed. Complete the installation by tightening the second hose clamp and installing the fuel cap.

Best of luck with your filler neck woes.

Did this at the weekend exactly as Lilred66 said and it worked a treat. I put the filler tube and grommet in hot water to soften them up and used a little Vaseline to help them together. New grommet looks much neater and I left a minimal amount protruding and the 'GAS' cap nice and straight. Best thing is no fumes in the cab now!

Thanks guys, Limey
