Anyone got any Renix fuel injectors floating around for my '89 4.0?

Are you looking for stock 4.0 injectors?

Yup. They fit 1987 to 1990, for the Renault/Bendix system.

I only have one leaking, and I am not completely sure it's not just "O" rings. I haven't pulled it apart yet. Just hunting for spares if it is actually a bad injector, and to have some on hand for later down the road.

The thing runs great, even with the leak, so I am hoping just an "O" ring kit and a little time.

I am thinking that the cold weather just polished the old "O" ring off as soon as pressure hit it. It was about 23* when I fired it up Monday morning.

The Renix system depressurizes after a minute or so when the fuel pump is shut down. It does not stay under pressure, as do some systems. Renix systems always have to crank a few more seconds prior to firing, since pressure must build up from zero.

It was actually interesting watching the leak, as I could clearly see the injector pulsing each time the cylinder fired. It is a seeping leak, too, not a spurting leak. I did drive it home just fine, I was just quite concerned about a wet injector that could have started leaking a whole lot more.

Send a PM to chaser. He may have what you need.

Well, the day was warmer, so out came the wrenches.

Bottom line, some bad "O" rings, but two of the injectors are leaking at the seams - so instead of fooling with the two-piece Renix injectors, I am searching for a set of solid replacements. Gonna do the whole job and do it right.

What I'd like to find, if anyone out there has a set, is some late 80's/early 90's Ford/Bosch (yup, I said it :lol: ) injectors. They are one-piece, rated at the same rate as the Renix ones, and will pop right in.

This style, not the earlier two-piece.
