GTR 94 Posted October 25, 2005 Share Posted October 25, 2005 hi i currently have a lil problem with my injectors and fuel rail, i have standard injectors and fuel rail on my r32 GTR and i have found fuel leeking at the top of the injector beetwen the o ring and the fuel rail. does anyone know where i can find these o rings? i have replaced them with some others this mechanic guy gave me and i think there worse than the originals? is there any secrets in fixing this problem? ohh and it usually leaks the worst when its just sitting idoling not when its reving or under load. thanks Link to comment https://www.sau.com.au/forums/topic/92404-injector-o-rings/ Share on other sites More sharing options...

GTR032 Posted October 25, 2005 Share Posted October 25, 2005 I've replaced the 3 rubbers on each injector after a few started leaking. Total cost for the 18 required was about $160 from nissan!

WetGTR Posted October 25, 2005 Share Posted October 25, 2005 The nissan ones would be good and they can't cost too much just when you re-install them, spray some WD40 on the o-ring part so it goes in smoothly into the fuel rail.

WetGTR Posted October 25, 2005 Share Posted October 25, 2005 You can always go to a place that sells bearings and o-rings. Got to be cheaper there! Just take in the injector and fuel rail and they should have what you need.

Gav Posted October 25, 2005 Share Posted October 25, 2005 Ludowici is your friend. You'll want to use the "nitrile" compound. http://www.ludowiciseals.com/pdf/Ludowici_Seals_O_Rings.pdf Link to comment https://www.sau.com.au/forums/topic/92404-injector-o-rings/#findComment-1667313 Share on other sites More sharing options...

SteveL Posted October 26, 2005 Share Posted October 26, 2005 Not sure where the 18 seals number comes from, but on an R32 GTR there are 6 injector-to-fuel rail O-rings and 6 injector tip seals (Nissan calls these 'insulators'). All these are about $6 each from Nissan (trade - that price was valid a few months back when I did mine). The tip seals are also available at injector specialists and they will also have O-rings (of course), but I found that the aftermarket type wasn't 'quite' the right size and that might be why the OP is having trouble with the one's the mechanic supplied. In any event, do them all if anyone is going to the trouble of taking the rail out - a leak in that area is not something you want to live with.......
