Car Forum / Peugeot Cars / April 2006Split Injector Pipes
To keep it simple... I've had three split injector pipes on three consecutive days this week! Ideas anyone?? Apart from gremlins with a hacksaw, I (nor anyone else) can think of any good reason for it. TIA > To keep it simple... I've had three split injector pipes on three > consecutive days this week!

The mechanic was not letting me go until he found out what the problem was though... and we thought he did find it - there was a bolt missing from the underside of the pump which he duly replaced, and I set off confindent that it was finally sorted - Travelled the 70 miles home and another one has sheared off about a mile from my house!!! That was two fractured pipes in the space of two hours... no one has a clue what to do with it now... How exactly are they shearing off? Are the unions actually comming out off the fitting itself. Are the pipes shearing off at the unions, or are they coming out of the end fitting themselves. A picture would help. If the pipes are physically breaking I would suspect a vibration issue. If the connecting unions are coming out of their fitting (stripping the thread) maybe they are the wrong unions (wrong thread or material). If the pipes are bursting or facturing it may be a problem with the pressure in the system ( though I did not think that it was possible to get enough pressure up to do this). Or alternatively if the pipes are stretching their flare and pullling out of the union you might be fitting the wrong type of pipe into the system (too soft a material). You should be able to get your injector pump tested by a specialist and get the correct pressure set. If this bolt that was missing of the pump, was it to do with the pressure regulation? Or is it a red herring? Is this a HDI engine?

BTW, are we talking about injector pipes or return pipes which are fit from injector to injector ?

I assume the missing bolt is the rear mounting bolt, and this is quite a coomon fault and the main reason why the pipes break. Make sure all the pipes to the pump are slackened off, then tighten all the mounting bolts (three at the front and the rear one) then tighten the pipes to the pump. This is what you should do when the pump timing is adjusted. Slacken the pipes, adjust the pump, tighten the mounting bolts, then tighten the pipes. Otherwisw there is undue pressure on the pipes and they shear. They were shearing off just behind the union at the pump end. After my last post, we found what it most likely to be the problem. The bolt the guy had fitted in Aberdeen, which was nigh on impossible to get into (directly underneath the pump) had worked its way loose and was lying in the bottom of the engine bay. I'm not sure what exactly the bolt was for, but by the looks of it (he fitted a 10 x 30) it was just a securing bolt for the actual pump unit itself. But how anyone is supposed to access is properly, I have no idea, as it's in a nightmare position... Will let you know... >They were shearing off just behind the union at the pump end.

You have to have the correct bolt which is a shouldered tapered type. Get it from your dealer. It is difficult to fit but not impossible. Thanks for all your help guys - I've now replace the four injector pipes again, along with a new set of four bolts for the pump from Peugeot, which included the different one for the back of the pump - Have driven 350 miles, and no problems whatsoever. >Thanks for all your help guys - I've now replace the four injector >pipes again, along with a new set of four bolts for the pump from >Peugeot, which included the different one for the back of the pump - >Have driven 350 miles, and no problems whatsoever. For further information. If in the future you need to adjust the pump timing, ALWAYS loosen the pipes before you move the pump. This will lessen the strain on the pipes and prevent them from breaking.
