The short flexible pipe from the filter to the tandem pump (at the pump end) is weeping at the joints and has been chafed over the years by a clipped-on support bracket for a water hose alongside it.. I have replaced the spring clips with jubilee clips and this has cured one end. The support bracket was not doing anything so I have removed that.

I wish to get prepared before doing this job and want to know what problems I am likely to encounter.

1. I need to source reliable, quality pipe, any suggestions please. I am aware that there are some very good looking pipes about, even at dealers, that rapidly deteriorate and become dangerously brittle.

2. Will breaking into the system bring up a fault on the ecu that I cannot resolve ? 

3. Having fitted a new pipe will the system self prime or do I need to bleed it somehow ?

4. Any other problems you think I might encounter please. 

It seems like a simple job, but I think the devil may be in the detail.

Can I just confirm this is a 2010 Fabia?

Make sure the new pipe is proof against E10 fuel!

@KenONeill

It is a diesel, so what you really need to be sure is not to run it on petrol.

yes it's a 2010 Fabia3 1.4 Diesel TDI

@uncle fester I had to check myself, but the reason your thread was moved and for the conformation of model year is that the Fabia 3  started in 2014 so yours should be a a Fabia second generation.

 

If your concern is about the quality of fuel or rubber hose then you are correct to be concerned as for the last 15 years I've had problems with ****-poor rubbish rubber parts and (petrol) hoses, all wrongly or badly made.

 

If you stick to reputable brands from reputable suppliers you should be OK, I'd go with brands like Goodyear and Gates but there others and smaller brands that will be good.

 

Getting lots of different products are currently difficult, I'm waiting for my third choice of tyres as stocks are low or unavailable in time for me.

Mk2 Fabia 3 (A trim) were on the go for a few years before a 3rd Generation Fabia so a Mk3 Fabia.

 

You can not turn back the clock.. 

 

The OP was moved because it was in the Hellos and goodbyes' section and not in the Fabia Section for Mk1, 2 or 3.

Sorry I mixed up my generations and marks, I am very old with wonky eyes,  skim reading when I can't, and overheated (before the thunderstorm anyway).

It just says Fabia 3 TDI on the tailgate, so that's what I'm going by, definately 2010.

 

Any news on whether it will self prime and / or will it bring up a fault code that I cannot clear please.

Dunno about priming but I can't imagine you'd have any trouble with fault codes.

How did you go with the change? Any issues with the priming? On my old transit I was advised to fill the new filter with diesel before fitting it, to avoid issues. That looks tricky to do on the fabia units, need to rig a hose rather than just pour it in. 

Fabia at that age is 5j, or mk 2, pre facelift... The 3 refers to the car's spec. (Arm rest, trim levels, etc).

 

I think I had exactly the same pipe wear out and leak on my car, some months back. It was a short piece of hose, about six or so inches. it connected a metal pipe that runs along the front of the engine,  to the pump and is made stable by a kind of double plastic clip that clips two hoses together to help prevent movement. Jubilee clips (Stainless if possible) are easier to use then the old squeeze-types unless you have the proper pliers to do them. I purchased the pipe and clips from a local car parts specialist, called I think, Clarkins, on Forest Road, Walthamstow. They even cut me a piece from the bit I purchased, to just slightly over the original size, to allow a little more flex to help with vibration. (Less pull on the hose). It is easy to cut but I would have used a knife, where they had cutters, which make a nice clean accurate cut.

I cannot remember the hose size but think it was something like an 8mm bore. The main thing is to be sure it is suitable for diesel fuel and the seller should know that. Aside from undoing the clips, prying off the hose and re-fitting, there should be no other worries as the pump will self prime. you might get a small amount of diesel leak when removing the hose but thats to be expected. I will try to load a photo to see if its the same hose as you mean but if you follow the metal pipe, it then goes back to rubber hose and goes in to the fuel filter, just behind the offside headlight. That hose too, is of the same bore and as it is standard hose, should be easily obtainable from most motor factors. Skoda main dealers only list the complete metal/flexi-hose as a unit so its quite expensive to buy like that and you would most likely only swap the rubber bit anyway!

MGRF   That is very interesting. Yes I think it is the same pipe. When I removed that double plastic clip, the vibration of the pipes seemed to improve, therefore as it was starting to wear through the pipe, I intend to leave it off in future. It's reassuring that it seems to self prime and it doesn't sound as if you had any fault codes appear as a result of fuel pressure change whilst filling up, so many thanks for your assistance. I will attempt the job within the next few weeks and see how it goes.
