Leaking fuel pipe

[buba]

I was planning on replacing the fuel lines while i have the car in bits, but the other day my wife said she could smell petrol. I looked all over the garage checking the car and my boys bike but couldn't see anything.Next morning i found a stain under the car and found the culprit.

Question is, this goes through into the car and i'm assuming directly on to the tank, has anyone replaced this pipe or had the fuel tank out?

Can you get braided lines for the fuel system?

thanks

The rebuilt cerb on the ramps at Neil Garners open day had this pipe replaced with a braided one. I asked the tech that was doing the job how he got the pipe off and he said the tank had to come out.

I feared that I'd have to take the tank out, do you know how it comes out and where the braided line can be bought from?
Thanks

There's another thread here http://www.pistonheads.com/gassing/topic.asp?h=0&a... which shows some of the detail of the tank and hose layout and i am sure i have seen some mention of how to get the tank out in a thread somewhere else.

I don't know the pipe size but you could pull the pipe off the pump end and measure it then buy the pipe from Tweeks or here http://www.cbsonline.co.uk/category/Fuel_System/Fu...

Thanks for that Ian, I have the pipe off as I needed to drain the tank so can measure that and job for Friday is to get the tank out.

If this is the pipe from the tank to the pump it can be done in situ.
Did mine, but had to saw the jubliee clip off with half a hacksaw blade as the jubliee was was fitted social couldn't get a socket on it. Pipe I got r9 off ebay .

Finally got the fuel tank out today, what a job, there's two straps that hold it in place so only four bolts one of the floor bolts needed cutting off but hardest part of the job was getting the carpet out of the way.

I'm going to replace the pipes with a braided line both the feed and return.

On the top of the tank there's a connection that goes to what look like a small pump then to a cylinder in the wheel arch, can anyone tell me what this is for.

Thanks.

If you mean the hose that connects to the filler pipe then the 'small pump' is the roll over valve and the cylinder in the wheel arch is the carbon can.

[buba]

Yeah thats the one, excuse my ignorance but what is the carbon can for?

Its a filter to stop the petrol fumes venting to atmosphere. There is a purge valve that the other carbon can hose connects to. It runs down the transmission tunnel and connects into the inlet manifolds via a 4 way connector at the back of the engine. On a 4.2 its above the coil packs. Not sure where it is on a 4.5.
When the engine is running the ECU opens the purge valve so the fumes are sucked into the inlets.

[buba]

ok thanks, is it something that requires changing?

Finally got all the fuel lines, bit disappointed that I couldn't get Goodridge for the return lines but once the are heat proofed you won't see the horrible black pipe

[scotty_d]

Looks really good, who did you use to supply all your hoses and fittings?

[buba]

I got all of the Goodridge supply lines and fittings from Cam auto developments and the return line from Flexiducting.co.uk. All the lines are PTFE lined and rated for the new ethanol fuels.

My new Goodridge line fitted, 1 job off the list

Old thread but finally going to be doing this with mine this summer so was doing my research

@buba Is that Goodridge Firesleeve you used to go over the return pipe and out of interest why couldn't you use the same braided line for the return as you used for the feed?

Really not sure about using braided hose for the fuel lines.

Firstly the fuel pressure is not that high to need braided hose. Secondly you can no longer see the condition of the hose so the first thing you will know of a degrading hose is a leak and potential fire. They look good but are they the way to go?

Agree with this, much better to be able to physically inspect the hoses, and replace when necessary.
