Injector Removal - High Pressure fuel hoses - DIY?

[BenB]

I'm about to remove my injectors to get them cleaned, and realised of course that the high pressure fuel lines (brass connections) are one-use and need replacing once they've been undone.
My stepdad has the kit here to pinch in the unions, I know he's done a few brake pipes on my step-bros car, I'm just wondering if the same kit is exactly what is used to make up these fuel pipes?

I don't want to cripple my car!

Out of interest, I have a very slight lumpy idle (tbh I just went out in it and ever noticed anything, but whenever I'm in the car with the wife she seems to make it happen!) and rather than just stick a bottle of cleaner in it I thought I'd send them to www.injectortune.co.uk who are charging £95 including return post to strip/clean/rebuild my injectors.
Like I say it's not a serious issue with my car, but I figure after 118,000 miles it feels like a good 'service' thing to do!

Anyone removed their injectors? Any issues? Think this is worth doing?

To get it running again after the fuel system has been dismatled I guess I need a primer pump. Any tips which size I need to fit inline? Can I install one to leave in the system?

Hi, please do not use brake fitting on your common rail engine, the operating pressure are in the region of 1800 bar which is really high. Something's are best done right.

Absolutely do not fabricate your own high pressure fuel pipes!! it's not so much a case of they will leak a bit - a fuel stream at 30,000 PSi can penetrate skin.

Your lumpy idle might be more to do with worn engine mounts, I'd check this out first.

Thanks for the response guys! You've made me stop in my tracks and not just jump in and start dismantling! Who would make me new fuel pipes, or are they supplied ready made form Volvo?

I'm putting doing anything at al on hold at the moment, as for the last 4 days or so the car hasn't done this once! Running and idling smooth as anything no matter what the revs are!

I really wouldn't do anything major until you can diagnose why it's running lumpy. If it's really bad and you can get the codes read then you should have more idea as to what's wrong.

You shouldn't really need an injector refurb yet, in fact no-one bothers usually. Peugeot HDi injectors happily run to 200K without being removed. All depends on how the car is used/serviced etc.

There is a way of testing the injectors by looking at the voltages and duty cycles etc. I believe you can pin-point an individual injector without removing them.
