So, my 90 4Runner, 3.0l has had a gas smell, and I finally narrowed it down to what I thought were injector o-rings. after removing the plenum, I wanted to verify that it was the o-rings, so I used regulated shop air to pressurize the fuel system. Unfortunatly, the fuel is leaking from the fuel injector, where the plastic, and the metal meet. So, heres the question, should I replace it with a factory piece, or get one from one of the aftermarket companies? I do not want to wait that long, with my vehicle down, but I do not want to be raked over the coals either. What is everyones experiences with both routes of
injectors? Thanks for any help, Jarrod

 

I had all my injectors flow tested, new o-rings provided by witchhunter.com 15/each.

NAPA carries the o-rings for around $5/ set
