Fernando87mj Posted July 26, 2014 Posted July 26, 2014 My 88 mj is leaking fuel from/around the injector again :( . I replaced them 2 months ago because the old injector orings where leaking so I replaced it with a napa oring set and had they had been working flawlessly until today. I Smelled a strong fuel odor and I immediately shut it off and opened the hood and saw that #5 fuel injector was leaking . So I want to ask you guys What kind of fuel injector orings do you guys recomend ?
Strokermjcomanche Posted July 26, 2014 Posted July 26, 2014 I've always used bwd o rings . When I install them I use a little Vaseline to coat the rings so they don't bind or get cut . Iirc the BWD part number is 274572 .
Fernando87mj Posted July 26, 2014 Author Posted July 26, 2014 I used bearing grease since I didn't have oil on me at the time , but thinks for the input I appreciate it I'll check out the bwd
88ComancheMitch Posted July 26, 2014 Posted July 26, 2014 Make sure you have the clips on good. Mine were loose and 2 injectors were leaking.
cruiser54 Posted July 26, 2014 Posted July 26, 2014 If those are stock Renix type injectors, it's most likely the injector itself leaking. Known issue with the Deka injectors.
Fernando87mj Posted July 26, 2014 Author Posted July 26, 2014 Okay I'll check the clips today , and thanks for the advice guys I appreciate it :)
Eagle Posted July 26, 2014 Posted July 26, 2014 I used bearing grease since I didn't have oil on me at the time , but thinks for the input I appreciate it I'll check out the bwd Not sure, but I don't think bearing grease is appropriate. Vaseline is what I have always seen recommended for injector O-rings.
Fernando87mj Posted July 26, 2014 Author Posted July 26, 2014 Oh I see I'll try to replace the o rings today again to see if that's the problem and I'll use Vaseline this time .
88ComancheMitch Posted July 26, 2014 Posted July 26, 2014 Oh I see I'll try to replace the o rings today again to see if that's the problem and I'll use Vaseline this time . I'm sure you are, but make sure you are getting orings rated for fuel.
cruiser54 Posted July 26, 2014 Posted July 26, 2014 I use clean motor oil. Just a warning: If it isn't the o-rings, be prepared. Carry a fire extinguisher? Never really understood how an injector that squirts out it's tip, into a manifold full of air, could leak fuel through the o-ring sealing the air in......

Good point -- especially since the manifold is under vacuum, not pressure.
