OK, so I am doing some small upgrades to my rig since it was run down and fairly anemic.
Just installed an HO head from a 1993 and while it was down I wanted to replace the fire-waiting-to-happen-injectors with some FoMoCo yellow tops. Did a lot of research on these before the install and I gotta say the research paid off. And from all the people who have said "be patient with this" all I can say is listen to this. If you try to rush it all you end up doing is destroying a whole new package of o-rings.
I used injectors from a mid mileage Mercury car with a 4.6l engine. The particular injector number was Ford P/N: FOTE-5DA or Bosch P/N: 0280150943. These are 19lbs./hr. injectors and so far are working great. While I had everything taken apart I noticed the o-rings in the fuel rail lines were starting to disintegrate so those are getting replaced too. And for those of you with Renix rigs those o-rings are a pain to locate so here is the part number: 217-3366. From ACDelco and I ordered them from RockAuto.
Just wish I could find a header premade for the Renix setup with the egr tube bung already welded in.
Next project, money allowing, will be to swap over to an OBDII setup and put a '99 intake on it. Can anyone say yay for installing a new wiring harness?
