Filler neck help

Post

Back to the top
Hi, looking for a bit of advice on fitting a fuel neck. Took old one off and noticed there was no proper gasket between the filler and the body. The car is an 1989 1.8 carburettor clipper cabriolet. Question is do I need the gasket only or the support ring as well. Also there are two different gaskets. One for carb and one gti. What’s the difference? They look similar in photos.
Any advice would be appreciated.

if you're talking about the foam gasket in behind the body where the filler neck meets in then it's not strictly necessary, but it helps stop the filler neck rattling, helps it pull in to the correct angle and generally helps everything be nice and snug when fitting the filler neck.

The plastic spacer helps to centre the filler neck in the opening in the body allowing the screws to be done up easier.

Dunno why there'd be different ones for the GTI and the carb. Possibly due to the angle of the filler neck as the tanks are slightly different maybe?

If you can afford it then get both as it's the way it should be done.

If not then nothing will go wrong without them. Obviously as you currently don't have them.

Thanks for the reply Ian. I will get both gasket and ring then. I just wasn't sure because if you look at technical drawings on google, some have gasket, some have ring, some show both.

Did you get a fuel filler neck for a cabriolet as they are different from tintop cars?
The cheaper tintop car filler neck can be made to fit but it need a section cut out and the the end welded back on…..

Hi mark, yes it's a cabby filler neck. I have trial fitted it and even though it's the right one I think it will still need tweaking. Just ordered new screws and gaskets and rubber hose from heritage. I'll see how it fits with the gaskets when they arrive.

Check the filler neck fits and give it a seval coats of paint, (don't use Hammerite as it's to brittle and chips off) epoxy mastic or stone chip paint is good as it's slighty flexible and can with stand some stones thrown at it. I use both the paints I mentioned and a good coat of under seal then finished it with coat of waxoyl just to make sure it will last, my car is a daily so it’s exposed to all weathers….  :thumbs:

Will do that Mark, I was going to get a stainless steel one but they are pricey. Maybe in the future when the car has all other jobs done I might fork out for one.

Don't replace the fuel tank to filler neck rubber pipe unless it's totally fubared as replacements don't really fit very well and are a nightmare!

Hi Ian, I'm afraid it needs to be replaced as it's too short. Someone's be there before me and the old filler is actually made up of two parts and two smaller rubber hoses. I guessing they chopped a tintop filler down and rather than weld it they used a second hose. Thanks for the tip though, I'll see how it goes when the new parts arrive.
