19 pound injectors are gonna starve a stock 4.0L .
So I'd say it would have tobe the 24s if that is the choice.
What exactly is this supposed to do?

Jim, the Jeep injectors have 1 big hole. The Ford injectors have 4 smaller holes. The theory is that the fuel is a finer mist with the ford injectors and thus you get a better atomization of the fuel/air mixture.

the ford bosch is supposed to be the same inj. only it has 4 discharge holes, versus stock jeep only having just one. so the ford 4 hole will atomize the fuel better upon discharged.

If you've got a Renix 4.0 use 19lb, if it's an HO use 24lb.

No problem. FWIW, my rebuilt ones have been working great.

I've been using RC Engineering stuff for years.Sometimes all you need is a good clean and balance,especially if the engine's stock inside.There is a calculator on the site to help with injector sizing.

Do they have new o rings? If not, it's very cheap insurance. Also, IIRC, you should soak them in oil to soften them up alittle.
