Just finished front diff oil change (see other thread) turned truck on to move it off ramps and...

...diesel p1ssing down chassis rail at rear, right above axle, just below body.

Has anyone got any experience of replacing/repairing fuel lines at this point of the truck?

Ideas on a postcard please.

:(
 
yh - cut out the pipe from back to front and replace with rubber. Access to fuel tank via boot under a panel.... :)
 
:question

Q: What's the best way to cut the old fuel lines?

Hacksaw mate :thumb2

I plan on replacing mine from the tank down to the IP, problem is I need some Bio/Veg resistant stuff

Much easier job when you have done a 2" body lift :naughty

8 & 10MM copper tube is easily available along with compression fittings to suit. My boat diesel fuel lines were all in copper.
 
Got it!

Already lifted boot carpet and removed cover (shearing three screws in the process!)

Anybody got any thoughts on how far I should renew?
Just bin all the old shite. New pipe from tank to fuel pipes in the engine bay. Just forward of starter motor :thumbs

I'll have another crawl around tomorrow and see how far I dare go!

This vehicle is starting to feel like the Forth Road Bridge !!!

:flush:
 
yh I'd replace the lot if you can and remove the old pipe so that silly MOT man doesn't decide to fail you on "rusty" pipes that aren't even in use (like mine tried)

Don't need to worry about my MOT's, my mechanic and his team are superb.

He is an hour from me! My Transit has the EGR valve deleted off the system, I just tell him what I have changed and he just accomodates it. They are great for advice and have saved me £1k's over the last 20 years. If you need his number (Stony Stratford, Milton Keynes), p.m. me.

Will have a good crawl under the truck today and see if I dare replace the whole lot!

If you do, can you link me to the stuff you used so I can order some too :naughty
 
Aye, might not want to use copper if you are running veg oil (dunno about bio). Veg oil goes green when in contact with copper for any length of time, although I suppose the fuel lines don't tend to have fuel sitting in them for much time.
 
Recently did mine with copper not that easy to work with getting it all back in to original brackets.

Also broke off the bolts when removing inspection cover over tank but it leaves perfect size holes for m6 rivnuts.
 
Update time...

Ok.

Replaced the entire length of feed and return fuel pipe this morning.

Materials used:

5 mtrs x 6mm int. dia. fuel hose
5 mtrs x 10mm int. dia fuel hose
2 x jubilee clips
Cable ties x good handful
Insulation tape x small amount

Process:

Put insulation tape over open ends of each length of hose to stop chassis crap getting in the new fuel hose.
Taped two hoses together at one end to make it easier to thread through chassis etc.
Threaded pipes through access panel in boot through chassis following route of existing pipes.
Removed metal air scoop surround and removed fixing bolt for dipstick to allow a bit of extra hand room.
Removed existing pipes in engine bay and fitted new pipes.
Removed old rubber hoses from engine bay.
Working from engine bay backwards, cable-tied new pipes to existing fuel lines as they quite substantial to support the flexible new hose.
Connected new hoses to tank in boot access.
Turned truck over, started, ran, then died.
Pumped fuel primer, turned it over, pumped again, turned over, etc., until it started and ran.
At the lowest point of the old fuel lines, cut through both feed and return to drain diesel out of lines.

Done. :thumbs

Used existing pipe clips where they were right size, new feed needed larger jubilee clips due to larger outside diameter.

Thanks to everyone that gave me info on this job. Probably woouldn't have tackled it without your support. :clap:clap:clap

Got the pipes etc. from:

http://www.beal.org.uk/

They only sell fuel lines in 10mtr lengths, but that only costs £11.90 ! Delivery options are limited, but they despatched within 24 hours!
 
Great news and a great feeling when youve achieved something like this so well done you!
Mine ran better too after the pipes had been replaced.

So another membership tenner saved:thumbs
 
Yup, very pleased with myself!

Didn't even lose any knuckles or draw blood. Which is something miraculous in itself!
