Update on injectors - ZR-1 Net Registry Forums

Aurora40 · 12-11-2005

Just FYI. I hooked up the fuel lines, battery, and let the fuel pump run for a few seconds. Then I waited about a minute, and went around touching the bottom of each injector. I have 5 primaries that leak and 3 secondaries. None of them were dropping drops of fuel, but they'd soak my finger pretty good when I touched them.

Oddly all but one primary and one secondary that leak are on the passenger side.

I've already ordered the MSD secondaries from Summit, though they won't ship for another week or so. So I'll price out some Delphi primaries and go from there. Marc Haibeck has a set of o-rings that he says allow you to use a secondary injector in the primary slot, and I believe also the later 93+ primary injector too. If the 93+ primaries are significantly cheaper, I may go this route.

I also dropped the middle screw where the lines hit the fuel rail... It didn't drop out the bottom, I think it may be on some heatshielding or the tranny...

Or maybe under the coil packs. I fished around but couldn't find it. I'll try again later.
