Fuel leak leads to addtional problems
My wife's 68 beetle had the smell of fuel so I had a quick look underneath and noticed a slight drip from under the fuel tank just near the outlet
pipe. I touched it and it then turned into a slow trickle. ANYWAYS, I drained the fuel out and removed the tank as it will need to be fixed.
Question 1 - will this require someone special to repair the tank? I live on the Central Coast.
When I pulled the tank out, I noticed that the one of the pipes leading from the brake fluid container to the master cylinder had a damaged plug into
the MS (please excuse me if I am getting TOO technical).
This first image shows the pipe at the back which is fine.
Question 2 - can I get one of these from Repco or somewhere else or do I need to source one from a VW place? I have enclosed some pics so you can see
what I mean.

This image shows the seal that is not damaged. Looks all nice and snug.

The one shows the damaged one. It was just hanging out when I noticed the problem. Do I need to buy the whole connection from the seal to the
reservoir? Not that that is an issue.
I guess I then need to bleed the brakes? Also do I need to clean out the MS if petrol has maybe leaked in? I assume that the petrol leak caused the
damage.
Thanks for any guidance that you can provide,
John

Repairing the tank can be problematic, is it a pin hole. Holes are normally caused by rust from the inside, they can be soldered for a repair but
sometimes the repair is a failure as the rust just comes through somewhere else. You can get some professional tank repair systems from some panel
beater supply shops. You do you repair then add a cleaner into the tank, swirl it around and then follow by a special sealer.
Maybe look at a new tank from someone like Classic Veedub or Vintage. I myself have given up these types of repairs (your M/S as well) because you
can buy new parts for a little more than the cost of a repair.

The master cylinder connectors and plugs are available from various VW suppliers,possibly the guys who bought Walkers Of WoyWoy may still have a bit
of stock.
If you decide to get the tank repaired take it to a radiator specialist.

Took the tank to a mates place and he soldered it up and also put a metal piece over the leak to reseal it. Looks to be rust but was only a small
hole. Looks to have been repaired previously.
As for the MS part, will ring a guy at Tuggerah tomorrow to see if he can source one. A mechanic called Peter O'Toole.
I don't think I need the whole pipe fixtures, just the bit that slot into the MS and the small rubber hose that pugs into the main feeder pipe.

looks like your brake master cylinder has seen better days and If that was my car and I was fond of the person driveing it
I would buy a new master cylinder and get the
rest of the brakes checked to.
take the tank to a Radiator Place to see if is worth trying to repair or just buy a new one from Vintage veedub

Hi John,
Yes You can get the fuel tank repaired...
there are special kits for this....
water usually stays at the bottom of the tank..
I personally would get the master cylinder resleeved with a stainless steel sleeve and a kit put in it...
and new plugs on the top...
so it will be like new...
or You can buy a new one..
the blue brake hose is special... available from all VW shops..
so the pipes can be re used...
don't buy anything from repco auto one etc...
cheers
Lee
VW shops only...

I got a new hose from the guy at West Gosford - Peter Korsche (excuse the spelling) it was a blue hose. Fitted it with a few hassles. I took the
rubber seal off the plastic plug and fitted it into the MS. I then slid the plastic plug in. All nice a snug. Had a little trouble with the hose
fitting onto the oval inlet tube from the petrol tank itself. At one end the hose is round, at the other end it needs to fit to the oval part of the
petrol tank. Is this a special hose - as in round one end and oval the other - or is it a round one squeezed on to fit?
As for the brakes being checked, Peter went over them a while ago and I had a bit of work done so that is all good.
Cheers,
John

Do I need to put some kind of sealant on the hose that connects to the fuel tank to stop any leaks? I am having trouble getting the hose on snugly so
I am going to buy a new hose on the weekend and fit it. Would just like to know about the sealant and what I should use? Seems a silly design to have
an oval end on the fuel tank and a round end at the other end.....

What about some sort of sealant? Does your beetle have the oval shaped bit on the tank?

Do you mean the outlet for the fuel line, or to the filler cap?
I am pretty sure both of mine are round. I may have my tank out in the next week or so - I will have a look.

AS far as i know John the hose is a special one... I know later models had a round pipe on both ends.. [1971]
You don't need any sealant on the hose...
You can use a bit of petroleum jelly [vaseline] on the fuel tank to help push the hose on...
it will dissolve in the petrol anyway....
cheers

The filler cap end it is round (where the fuel goes in from the bowser), where the rubber pipe joins the petrol tank, that is oval. It is not bent out
of shape, that is the shape it is. I can't find an image on google. Has anyone else seen the one I have?

Hi
Mine is the same...
I have never seen one for sale anywhere... CIP1 etc..
the later ones are round both ends which makes getting a hose MUch easier....
I placed two hose clamps on each end....
was very difficult getting the tank back in....
never want to do it again...
or I'll have to replace it with a later round hose etc...
I have a later round one...

Lee,
thanks mate, at least I am not going mad....
Edit - the guy from vintage Vee-Dib informs me that it is a round hose on both ends. Will have to go the double clamp.
