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
