Guest SeanT Posted March 10, 2006 OK Im going to be removing my injectors at the weekend and sending them off for testing and cleaning, now as you may have gathered by now Im not the most mechanically minded person so this is a big thing for me So Ive searched the forum seen a thread on how to remove the injectors, remove the injectors from the inlet manifold and then off the fuel rail, the question I have is fuel going to continously leak out of the rail while the injectors are removed, if so whats the best way to stop this?? Thanks as usual guys.... Share this post Link to post Share on other sites
Anthony 1,003 Posted March 10, 2006 Some fuel will spill out (especially if you've recently run the engine) but it won't keep pouing out as the fuel pump won't be running Share this post Link to post Share on other sites
boombang 2 Posted March 10, 2006 take the fuel hose off the end of the rail or off the fuel filter (as its often easier) Either just put an 8mm or 10mm bolt in and tighten the clip back up or put a short piece of hose with bolts in or crimped if on the fuel filter. The injectors can be a real pain in the arse to get out the manifold though! Share this post Link to post Share on other sites
Guest SeanT Posted March 10, 2006 Hello mate, Thanks for that, somehow I knew it wouldnt be easy.....Ill just have to remember to not get to heavy handed and stay patient.... Any top tips for removing the injectors always welcome.. And thanks again for your help and advice the other night, nice of you to give up some of your time.....

Rob_the_Sparky 9 Posted March 10, 2006 take the fuel hose off the end of the rail or off the fuel filter (as its often easier) Either just put an 8mm or 10mm bolt in and tighten the clip back up or put a short piece of hose with bolts in or crimped if on the fuel filter. The injectors can be a real pain in the arse to get out the manifold though! Personally I wouildn't do that as I'd never risk damaging the inside of the pipe with the threads as it is this seal that prevents a fuel fire destroying the car (may be being paranoid but the thought of an engine fire makes me paranoid!). Leave them open with a bag taped over them to keep the crap out, next to no fuel will come out once the initial pressure has been released. Share this post Link to post Share on other sites
kate205gti 4 Posted March 10, 2006 watch your face when you pull the pipe off - petrol in ur eye stings like hell Share this post Link to post Share on other sites
Guest SeanT Posted March 10, 2006 Ill try and avoid that one thanks;) Share this post Link to post Share on other sites
M3Evo 0 Posted March 10, 2006 If it were me, I'd make bloody sure the system was depressurised before taking anything apart! Share this post Link to post Share on other sites
jackherer 543 Posted March 11, 2006 If it were me, I'd make bloody sure the system was depressurised before taking anything apart! I agree, just start the engine, pull the fuel pump fuse and wait for the engine to stop. Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted March 11, 2006 I agree, just start the engine, pull the fuel pump fuse and wait for the engine to stop.Doing this should mean thatwatch your face when you pull the pipe off - petrol in ur eye stings like hell doesn't happen. Undo the two 10mm bolts holding the fuel rail onto the inlet manifold & then a 17mm spanner at the manifold endof the injector & gently work each injector gradually out of its hole. Graham.

Guest SeanT Posted March 11, 2006 OK thanks for the advice the injectors are now out!!!, wasnt at all as hard as I thought, although some interesting findings...the other night boombang was checking the car over for me and plugs 1 and 4 were black suggesting running rich and 2 and 3 were like an ash colour suggesting normal or a a little lean.....anyways on injector 2 there was no clip holding the plug onto the injector so it was kind of loose also when I removed number 2 injector it seemed well clean and dry and there was no cap over the bottom of it, not black and oily around the rubbers like the other 3....anyways the plan is to ship them off get them cleaned and then upto the rolling road to try and get the fuelling etc all sorted..... Thanks again. Sean Share this post Link to post Share on other sites
Guest SeanT Posted March 15, 2006 Injectors are now back from cleaning, one had average flow all the rest good flow, they was all marked 50???and after cleaning they are all flowing good and have 54 next to all of them..........Ill post up if I notice any difference once I get the injectors on and the battery charged!!..

Guest SeanT Posted March 16, 2006 Oh my god, I really thought Id wouldnt see any difference especially going on the before and after results of the clean, but it pulls alot stronger and smoother......and the engine does seem quieter!!.....OK so now I need to book up the roling road!!! and sort out whats draining that damn battery!!!...

Jonmurgie 2 Posted March 16, 2006 Good stuff, glad to hear the car feels better! It's amazing that people don't geerally think about cleaning 15+ year old injectors Share this post Link to post Share on other sites
boombang 2 Posted March 16, 2006 phew! When you posted the results I got a little worried but goes to show that injector flow isn't the be all and end all and spray pattern is important! Share this post Link to post Share on other sites
