Rebuilding your 56 to 61 fuel reserve tap.

Guys I was going to add to this also. For some weird reason. My brand new fuel tap from WW the long brass pipe after six months of sitting the tall brass pipe was eaten of and clogged my tap. The only thing I figured was the previous owner had cleaned the tank with some kind of acid and it was still in the tank dried to the sides if that's possible. I am hoping it was not someone I work with as it has been sitting in the shop I work for. I didn't think that soldering the brass to the aluminium would work that great. Not saying it won't. I used a thread and tap. I bought the brass tube and used my die to see what tap would work best. I took and bent the tube slightly at the top so I could spin it in by hand. I think I used a 10/32. The I used the tap on the body and screwed the long bent pice into the short side first and cut then into the long side and cut. It seemed to work good. Just a thought for someone who doesn't know how to or feel the solder will hold.

Hello all,

I'm just trying to take my tap apart for rebuilding but the large securing nut is not co-operating in coming loose.
After a good bit of heat I can get it to turn about 45 but that's about it.

Anyone any ideas or should I not bother removing it if it won't effect how the valve seals to the tank?

Cheers

Use a good penetrating oil and work it back and forth so it gets a little more movement at each try. Also the thread on the tap is LH.

Hi Guys quick question,

What is the thread size for the nut and thread in bottom of the fuel tank?

Where the fuel tap/petcock attach. I just rebuilt my fuel tap and the nut has a few threads that need to be tapped with a die, and ill be cleaning the threads also from the gas tank. This for a 1957 Bug with a regular style humpback tank.

Thanks!

[Eric&Barb]

Better to use a hand wire brush on the outside threads and a dental pick or scribe to clean out the inner threads. Apply some oil on the tank threads and see if you can work by hand the nut onto it.

I have a 60 vw bug

I am trying to rebuild my fuel reserve tap, but, cannot get the circlip on

I depress the assembly down with a socket in order to secure the retaining clip, but, it pops out of place.

Here is what I have....(pic)

Other questions now arise... when I view the WW instructions, it shows an additional washer (beneath spring), and, an additional washer at the base of where the copper filter seats, neither of which were indicated as necessary when I bought the rebuild kit.

So, 1) does anyone have tips for getting the circlip on?, and, 2) do I need the additional washers described above?

[Eric&Barb]

Maybe try something like a thin dental pick to make sure the C-clip is fully in the groove and have a helper too boot to lend a hand. Make sure the groove is clean of anything else in it and undamaged.

Only need one sealing washer. Aluminum of the filter sock will mold to shape and seal also.

More info in the parts manual here:

Thanks Eric&Barb!

After hours of research, I found a lone post, that stated, the ring in a 'rebuild kit' was ever so very slightly thicker, and did not fit.

He went back to his original ring, and, perfection.

Precision is everything! Beware the supplier...

[Eric&Barb]

Thanks for that update! Been a way long time since we bought new rebuild kits. Back then they did not come with the rubber dust boot or the clip. Figures that the original is thinner.

Same problem has been noticed with newly made rebuildable fuel pumps that have too thick and strong springs causing too much fuel pressure. Solution is to install OG spring.

Eric&Barb, here's what I was talking about...out of Bentley....i.e. extra washer below spring and another below filter.

[Eric&Barb]

Interesting! Perhaps later on they decided the second sealing gasket was not needed. Even if it was half a cent savings, over 1,000,000 cars later that would be a nice savings of about $50,000.00.

Thanks

Just checked now, its $9 for the set, but $52 for shipping to Norway!!!

BTW anybody think its possible to make the gasket of some fuel resistant rubber?

Do a WWW search for "Reserve Fuel Tap VW":

Got this one result in the UK that might be better for you shipping cost wise. Did not dig further, but if they sell reserve taps and some of the earlier filter pieces for them they probably have the rebuild kits.

Thanks!

I did clean it properly, filled it with some gasoline, and it seems to be a leak free. I changed it because when I got the car, it had a leak for what seems to be the tap. But probably came from where it connect to the tank. Will try to mount it on, after cleaning the threads on the tank as well.

What is the proper way to mount it? Start with the nut of both the tap/tank, and finger tight it on both parts at the same time, or first on the tank, then the tap?

danny

Sorry, read "panicman"s description further up in this thread
