Hello,

I have done a lot of research (not enough appearently) on an injector swap for my 91 cherokee. I figured out what I needed and was going to go to the junkyard to find some injectors, but the night before I checked ebay and won some yellow, 4 hole injectors that were reman'd for cheaper than it would've been for the JY injectors. I got them yesterday and the they are definitely ford yellow stick injectors, with 4 holes, but the part # (which i didn't get to see before hand) is 0280150909 which is not what I thought I needed. Also, the ebay ad said "direct fit" but now I'm seeing I will need to solder clip nuts in? is this true? also, that I may need to change the FPR to one that matches the injector? I'm down with that I just need to know which one.

I know this may have been covered but my searches didn't come up with anything.

Thanks to anyone who can clear some of this up for me.

hers the upgrade list

Yup, I have that list. The ebayer I bought off was a power seller with a high rating I just assumed he would have the right ones, especially claiming they were a direct fit for my year xj. But the part # is not the same as what is listed for the ford injectors I need.

send them back or sell them

Thanks for the help. SO they are definitely NOT going to work? any body else chime in?

the other side says FOTE-B1A if that makes a difference.

I just checked the number on my injectors. It's the exact same number. I got them on ebay from a guy in Florida. They were plug and play in my '88. I've been driving with them almost a year, and my engine seems to run better - quicker start-up, smoother idle... not really much improvement in MPG, though.

The flow rate chart I got with mine said 210cc@43.5PSI. I don't know how that translates into lbs/hr.

They're from a 1992-1998 Ford 4.6 liter engine.

The 0280155710 injectors in the chart are listed as being from a 1997 Ford 4.6 liter (Calif.) engine on this page:

I've also been wondering if I should be concerned the fuel pressure regulator, since I have also seen that chart. But, I understand that there are a lot of people using them in their Cherokees.

Ah, thanks SNIDELYWHIPLASH I appreciate you putting my mind at ease. lol Glad to know they can work.

On the FPR subject, when I was reading about having to replace it, they claimed you should use a FPR out off the same engine the injectors are from. SO if they are from a 4.6L ford. this is the only result I came up with

Says its 41psi. I'm a have to do more research.

Confusing, isn't it?

Here are the stock fuel injector specs for your year:

Model Year, ......Part #, ......Colour, .....Fuel Pressure, ..........Static Flow,

'91-'93, ........33007127, .....Brown, .........39psi, .................21.0lb/hr

I found an online calculator here:
http://www.rceng.com/technical.aspx

The 0280150909 injector flow rate of 210cc/min@43.5 PSI works out to be 227.25cc/min@39 PSI, or 21.62 lbs/hr

That seems close enough to me. I would just put them in, and not worry about the FPR.

DieselD

awesome

I appreciate the time you took to say that. I may just replace my FPR to a new stock one if it's dirty when I take a look at it.

Thanks again.

Glad I could help
Let us know how everything works out...

DieselD

Will Do.

Ok, well I put them in some time ago, and I'm glad I did, the stock injectors were nasty, covered in gunk. The ones i got fit in fine, after comparing them to the old ones, he just added plastic pieces to make them fit like the stock ones, a little plastic spacer, and then a plastic endpiece with a little lip.
