Fuel Leak

BMCC · Post by **BMCC** » Tue Feb 25, 2014 6:25 pm

So as well as leaking PAS fluid, the car has decided to pee petrol all over the drive

(Well I'm trying to keep calm about it!)

Jacked up the rear and removed the fuel pipe cover to find the lower hose split. It's was dark and raining so that was as far as I got. The pipe itself goes up past the fuel tank and back to the pump (I assume). Does anyone know if it is fuel pipe all the way back to the pump (fuel pipe onto a solid pipe?) or do I just need a short piece of fuel pipe and a couple of new fuel pipe clips? If so what size of pipe am I looking for?

Cheers,

BMCC

Here's how the pipes look off the car, this is for my 4th, though I don't think the 5th is too much different.

Not sure what size rubber pipe you need (maybe 9mm?) but if you measure the external diameter of the steel sections and knock 2mm off that you won't go too wrong.

I had this, where the rubber fuel hoses come out of the fuel pump at the back, they have connectors that connect to the steel fuel lines that run under the car. Where the fuel lines run under the car they are coated in rubber to protect them from the elements, but where they connect to the rubber hoses (behind a plastic cover behind the rear passenger wheel) they are uncoated an had rusted away and started leaking.

I removed the steel line where it connects to the rubber hose, then where the steel line starts to run under the car I cut the line with a hacksaw where just where they start to be coated in rubber. I then cut 2 1/2 inches of the rubber coating off the line, got a piece of steel tube (about 4 inches long) the same diameter as what's already on. I connected the steel line to the rubber connector, then I bought some rubber fuel lines and fuel line jubilee clips and attached that using the clips to the new hose connected to the rubber hoses and the existing line with the rubber coating removed.

This basically removed the rusty unprotected steel line, with a rubber hose.

It looks like rubber hose all the way as far as I can see but I couldn't feel the pipe as the car was on the standard jack. I'll need to put it on ramps and have a look. Was hoping it might look like the ones in vtecmec (cheers for the pics), but I don't think it is. I had a fuel leak here before and drove it to Hyndland Honda (Well they were just round the corner

) for them to fix. Maybe they did what you did Rob?

Same! Without removing them you should be able to bodge some temp pipes in 8-9mm. High pressure fittings would be better or just swap them out like i did, about £40 each and an 8 week wait as they would go on back order from honda. Or make your own if your brave. The only prob with with bodging in a new section is securing it to the existing line as like mentioned it is coated with plastic but should be no drama. Check your fuel filler neck bend at the bottom cuz bet that will be rotten too

Possibly, that steel section that's uncoated before the rubber lines from the fuel pump is a week spot. Doing what I did by replacing it with a rubber hose its the easiest option. Have a better look and get some pics up.

Just to note, the rubber hose I used to replace the rusted steel section was a high pressure fuel rubber hose. I picked it up from my local motor factors, around £4 for 1 meter. I can grab the size of the hose if you need to know, because I didn't use all of it.

Yeh deffo easiest! Wouldnt recommend swapping all the lines out such a ball ache. Strange why they designed it like that tbh.

This is how my 4th gens fuel leak was solved. Cut a longer piece of new hose and push it past the original clamp points and clamp it further up the metal line.

Yes please!

I'll need to put the car on the ramps and have a proper look at the weekend. I've got family staying over from Fri- Sun so hopefully Sunday will be the dry day and not Saturday.....................
