Quick 'how to' replace fuel lines

[k.alle]

I haven't been under to have a look yet, is there a lot of twists and turns?
I was under the impression it was mostly straight piping back-front.

Might have to rethink then.

You will never get it to bend and follow the original path. Stick with 8mm cunifer.

It's now my turn to tackle this job.

I am thinking of fitting polyamid plastic pipes.


But I'd like to know what the diameters are on the OE piping.
I think it is already stated that it is 8mm outer diameter.
What about inner? 6 mm?

Got to figure that out in order to order the correct adapters etc.

[EDIT]
When I zoom in on OP's piping that he bought it has 0.75 mm wall thicknes which gives 6.5 mm ID.
Does anyone know if OE pipes share this ID?

I'm soon to tackle the corroded fuel lines on my ABY coupe, and found this thread very useful - a great write up.

To make the job easier, I'm considering removing the vapour / breather line. In doing this do you blank off each end? Also would it cause any issues at MOT?

This is a handy thread, and I'll have to tackle my urS6 lines soon. Just wondering if if ordinary C4 say 1.8L / 2.0L fwd cars have the same run of fuel lines as a urS6 C4 ?

Also I seem to recall that later model VW Passats, say maybe a 1997 model, used plastic petrol pipes with rubber flexible pipes at either end of the run of plastic petrol pipes under the main floorpan of the car ???

Was just wondering if anyone had tried the plastic petrol pipes idea, and how they got on if they did ?

Thanks for any comments either way.

Ok,i try to find in our town....And i decided to buy a OEM fuel hose,because of, after that years,they doesnt look too bad....

OEM number N 020 281 1

[Error404]

The best type are these - stainless Oetiker clamps

[Tom_]

do you have a picture, how they looks like?

[Christophski]

You can get specific fuel line clips which are similar to jubilees. Any decent motor factor place will have them.

They basically pull and grip all the way around rather than leaving a tiny bit I gripped by the fastener like jubilees do

fuel hoses

Hi alex, and which clips did u used? these?

[Error404]

yes that will work fine Tom

[Tom_]

Thanks alex,but i have no idea,where i can buy it...
What about these?

[Error404]

I think its OK to use rubber for short flexible pieces, I would use as much metal line as possible as it will not be damaged by stones etc hitting the underside of the car, i think rubber hose will deteriorate a lot faster. With rubber hose you should use the stuff with the cotton braiding to protect it

guys,is it right,to use a rubber hose on fuel?Look at picture. Its from tank hole to fuel lines around fuel filter





Or is better to use a different types of fuel hose and clips?Fuel hoses what i used is dedicated to use on fuel ...

[4WheelDrifter]

you need to flare the end of the fuel line:



Then use some 8mm fuel hose:



Then use a banjo with 8mm hose tail:

Now that is a quality answer.
