JeepcoMJ Posted February 2, 2010 Share Posted February 2, 2010 the '90 elim. had some pretty crappy injectors, and the o-ring for the fuel pressure regulator leaks. I'm wondering how much, if any, of an upgrade it would be to swap H.O. injectors in? any ideas on fuel mileage gain/loss? just a thought I had, as I'll already need injector o-rings and FPR orings anyways, why not do a small upgrade.
