Thread: 2014 diesel Hilux slow starting & loosing fuel prime.

Also fuel hose connections, hard pipe near mounting points etc etc. It's often surprising where these things fail - and it's an utter pain in the arse when they do as the volume of the piping is so small a little hole can allow a LOT of movement of fuel back to the tank in a very short time leading to all sorts of bollocks performance and running issues. It can often be a push in the wrong part of a hose unseating it just enough to break the seal if the rubber of the hose has compressed and taken a set.

Sometimes it's related to work, other times it's purely coincidental for timing and a stray rock or the like has bounced up somewhere and clipped a line under the chassis etc. They can be a bastard to find, as these can hold under pressure but not vacuum or vice versa. Used to have the hells own time chasing these down in marine installations, as half the time the bloody pipework isn't accessible so you end up having to reroute pipework which on commercial boats is an utter nightmare.
