Rusty fuel filler neck?

[ioboy]

Hi Everyone, this weekend I bought a beautiful 1984 mk1 1.6 GL cabbie. The car is in lovely condition (I'll upload a photo at some point) and I'd really like to take it to the odd show here and there.

The only issuse as far as I can tell is a rusty fuel filler neck, which has a little hole on its upper-side just behind the cap. Before this starts causing problems, I'd reall like to replace it, and maybe also try to get any residual crud out of the fuel tank using magnets (i read about this on another thread)

Anyway, I was wondering if you guys could offer me any advice on how I can go about replacing the neck? Do you know the specific part i need from GSF, for example, and if I found one on ebay, how would I know it was the right one? Is it a big job? Is there a thread I've yet to find explaing how to do it?

The car is garaged so I'm in no hurry to botch it. I'd really like to keep this beautiful car as sweet as possible.

Cheers

Also, I've heard somewhere about plastic versions of the fuel fille neck parts, do these really exist?

The neck is dead easy to replace, once you have the wheel off it becomes obvious what you need to do to replace it
The only thing I can add is that while the tintop filler looks the same, it isn't quite and requires a little work to make it sit properly.

I've not heard of plastic pipes myself!

I used to have a mk1 golf driver many moons ago with the same problem, even back then i was able to replace the buggered one with a plastic part. Try euro car parts. couldn't tell you the part no. though.

The filter is really easy to get off you'll have no probs, I've not heard of plastic myself either, there were stainless ones around years ago but I haven't seen them recently, I got an aluminiumized one from Volkspares for about £25 

  Once you've fitted it you'll need to give the fuel filter some attention - dont waste money on a new filter just yet (they're £15 each  )  take it off and blow down it in the opposite direction to the usual fuel flow (its arrowed) to clear the crud out.  You'll probably need to do this a few times before you get all the shiz out as no matter how carefull you are there's going to be loads of bits of the filler neck falling into your tank during the swap.  when you find the filter isn't full up with cr@p every other day its time for the new one

just to note a mk1 golf gti fuel filler neck is different from a cab one and for some unknown reason they are double the price as well... (shocking but true)

Sound advice from mk1mad J (Jason) I would personally take the fuel tank out and clean it properly to make sure everything is out.
