Fuel Pipes sizes from the petrol tank. B2 1983

[billy_bunter]

I still have the original 'plastic' pipes that do the feed and return on my B2 Carb car. What have other people used. I cannot find the modern equivelent online.

ETKA
Feed - 812 201 223 C
Return - 812 201 229 B

Has anyone replaced them and if so where from. VW heritage do a 'braided 5.5mm hose (N90099601) would this do the job? Looking at the pipe ends in the engine bay they are different sizes.

Did you have any luck finding a replacement? I recently tried to replace my fuel filter and cut these factory fitted heat fitted fuel lines to help me remove my fuel filter. Obviously this was a massive cock up on my part & now I am struggling to get any fuel pipe to handle the pressure & stay attached.

Hopefully you are sorted by now. I was in the middle of replying the other day when the site went down.

No I did not find direct replacements. I wanted to replace the whole length as the pipes are 35 odd years old. I did have dreams of trying to restore rather than 'get working'. I could only find modern 8mm ID fuel pipe at a reasonable cost. My car has 2 sizes one for feed (IIRC 6.5 or 7mm ID) and one for return (IIRC 5 or 6mm). Both way smaller than 8mm
As suggested on another forum I went into Pirtek with a few offcuts and what sizes I needed. They were really helpful. I came out with a some double sided barbed pipe joiners and hose clamps.

Hose clamps

I then sourced 3 odd meters of fuel pipe from VW heritage. Along with some jubilee clips this enabled me to join the feed pipe using a joiner to the petrol pump to evaporator to carb. Then a pipe jubilee clipped to the return. I do not have the pressure problems you have as I run a carb! If I remember I will post a pic later.

As others have suggested get some pipe the same ID as your Barb fittings and use some of the clips I posted above. If you are lucky ETKA(7zap) might give you those dimensions from the comfort of your chair.

Most good hose suppliers will have both. Make sure you buy petrol resistant pipe! I got the impression the Pirtek branch I visited were used to random classic car people wandering in....

Pirtek - that sound like a plan.

Clamps - really those are a better option? I am using a standard pipe clip you would use on a radiator pipe. Correctly sized obviously for the 7/8mm pipe on the fuel line.

VW Hertiage - I went looking there and didn't have any luck, some suggested Audi Hertiage. But struggled with them too..

I need these obviously "double sided barbed pipe joiners"
But no doubt there is a technical term I need to figure out

Thank you for all the replies.

What car have you got? Model year etc

On the vw heritage site you have to look at golf stuff or know what size pipe you have and then ring them.

It sounds to me like the pipe is too big What id pipe are you using?

The o rings on the link I did were called double ear clamps and o clips. Good place to start searching. Pirtek will have all of that. Take your original pipe along with the old filter and the new filter....

Found a pic...

Top is feed, Bottom is return. Middle is speedo. Petrol pipe to the right is the braided sourced from heritage.

You can just see the blue barbed reducer on hte feed pipe join.

Ok, I have a 1983 Audi 80 Sport on a A-plate, which is an 1.8i with FWD.

And i am referring to the fuel filter at the rear / under the car / on the drivers side. Just incase i didn't make this clear in my earlier posts.

I have noticed that parts do fall under shared parts with the Mk1 Golf with the same engine. ie Mk1 GTI 1.8 8v

So how do double ear clamps secure the pipe any better than a standard hose clamp? What am i missing?

When I had my WN coupe I replaced the lines for custom braided versions with the correct ends already made up. Think it was this company but it was a long time ago.

Custom correct ends that can slip on to metal barb ends/metal nipples? Sounds perfect what is the correct end?

I only see the standard choice of pipe work on Vipers page, but interested in this custom correct end information.

Thank you

Just wondering why youd need to replace them? Are they leaking?
Made from nylon iirc that lasts donkeys years.
Im sure you could get replacement pipe to suit from a tubing supplier alternatively replace them with Kunifer (copper/nickel).
