If you are getting better mileage than you are getting less

Re: Jeep yj 4cyl performance fuel injectors swap
Not necessarily. He could be getting more complete combustion. Four holes
instead of one could mean better atomization of the fuel. Or it could mean
that he is driving the vehicle better, because he knows that there are
different parts in it. It takes a while, and it is tricky to get good
mileage measurements.
I don't know about this though

"It won't fit" doesn't mean "you don't need them".

instead of one could mean better atomization of the fuel. Or it could mean
that he is driving the vehicle better, because he knows that there are
different parts in it. It takes a while, and it is tricky to get good
mileage measurements.
I don't know about this though

Re: Jeep yj 4cyl performance fuel injectors swap
Not necessarily. He could be getting more complete combustion. Four holes
instead of one could mean better atomization of the fuel. Or it could mean
that he is driving the vehicle better, because he knows that there are
different parts in it. It takes a while, and it is tricky to get good
mileage measurements.
I don't know about this though

Re: Jeep yj 4cyl performance fuel injectors swap
BS, you want to know, can I drive up that hill faster than the
fifty miles an hour last time! If you do you will be using more energy
(gasoline.) No the oil companies don't hold the patent on that fifty
mile carburetor. As it would only work on that same fifteen to one gas
ratio.

Re: Jeep yj 4cyl performance fuel injectors swap
This project was to see if i could get some horsepower gains not so
much gas. Don't quote me on the "better gas mileage". The way the jeep
is running i can tell that there is a difference maybe a better
combustion due to the 4 hole design. The gains i recieved from this
upgrades is noticeble and fullfilling i do recommend it. As far at the
retainer clips are concerned , so far i've seen no leaks and everything
is sound. The ford injectors are a tad bit longer and when the fuel
rail is bolted up it adds a snug fit but i will find a way to make or
buy a retainer clip just in case a the high pessure side were to aid in
some sort of leak. But as far as i'm concerned i'm not worry about
it. If someone else decides to do this injector swap then you can find
or make a retainer clip. As far a hp gains , there is a difference i
know that there are new parts in the jeep but i did go on a pretty
extensive ride and monitored it. If i didn't think their was a
difference i would probibly sell those injectors and make a pretty good
penny but it works so im satified with. The fact of the matter is that
with the mod's i have now this swap complimented the performance on the
vehicle. But hey thanks for writting in. If anybody knows of any
interesting mod's or just some interesting tips for the 4cyl drop a
line until then Cheer!!! Jeep Rio
