FI Rubber Seal change ?
Hey gang, got the rubber seals on the fuel injectors changed and 'ole girl is back together again. Question is this, not having the money to buy new FI Insulators, I tried to use JB weld to fill-in the busted out pieces on the insulators, immediately after starting the engine, the jb weld pieces came out, am I right in thinking that the new seals should be allright with these insulators not entirely complete, at least for the next 4 to 6 months, in other words, they shouldn't leak again for at least a little while?
Thanks gang

Re: FI Rubber Seal change ?
Ok, I think your fuel injectors are leaking and you are trying to fix it buy buying new seals and insulators. That will not prevent them from leaking. You need to buy new injectors if the injector itself is leaking fuel. The lower rubber ring seals the injector to the engine. Besides that, you can have a cracked plastic insulator (older 280Z's have aluminum) and they will be fine as long as the injectors are ok.
My plastic insulators cracked when I gently screwed the injetors in. I pulled the whole fuel rail and replced them with another set from Nissan and they cracked again! (this is while I'm installing NEW fuel injectors) so I decided to leave it alone and see what happens. 3 years later and 50,000 miles have gone by and no fuel leaks. That plastic sleve is just a holder. It is not holding fuel pressure.
