Wedge fuel hose recommendations.
Discussion
Hi Peeps
I know this subject has bounced around more than a rubber G-string but a few months back I decided to change the fuel hose run from Swirl pot to fuel rail, I bought up-to-date marine fuel hose that was recommended for all fuels including those with high ethanol content....However I can actually smell fuel permeating through the hose already, There is nothing leaking but you can smell the fuel all the way along the drivers side and on the feed in the engine bay.
My guess is that I was probably sold old stock or hose on the cusp of the change in the ethanol content....I would prefer not to die in a ball of flames via a fuel sprinkler system so has anyone else had any issues like this...Can anyone recommend a good supplier please, The one I used has been good albeit expensive the last 6 years...
Thanks
Regards
Ziga

I think the problem is temperature, not ethanol. Is the pipe running down the tunnel in the middle of the car?
I had quite new R9 hose crack externally on my engine's fuel rail. Look carefully at the spec of the hose and make sure it's good for approx 125 DegC, some hoses are only rated up to 80 DegC, that's clearly too low. I put Gates hose rated to 135 DegC on last time, it's been OK so far.

I had to replace the fuel rail hose twice in 6 months...Yep hose running in the tunnel.
I have used this

and then the R9....Maybe go for Gates or something similar....I did hear that copper can suffer from fuel evaporation from the heat from exhaust etc......??

Bit of 8mm Kunifer pipe should do the job
I was thinking this...Not from the local plumbers...The Hatter said:
I was concerned using the rigid pipe without some kind of roughness/barb to stop the pipe slipping off, although TVR did just that. The fuel rail has loads of connections without barbs too.
I experimented with 8mm gas compression fittings; I tightened the fitting to get the olive to clamp onto the pipe and then cut the compression nut to get it off the pipe. Worked OK and no heat involved. I did this on the main fuel feed to the rail where you get pressure, heat and engine movement/rock all working together...

I did wonder as regards to this and the kind person who will be fitting it for me has the the tools to put a lip at each end of the pipe...Although it should in theory be okay with the rubber connections pushed tightly on and then clipped.
Ill probably go for a finished end rather than a plan one...
Cheers
Had the feed run in 8mm kunifer, The end was knurled so a tight fit...Paul also covered the section near the exhaust with the old hose and where its strapped to the chassis.
So far there are two advantages of this...
1. I no longer can smell fuel along the O/S edge of the car
2. Seems to start better and have a better throttle response
Having peace of mind is a great thing...
