ID these fuel injectors?

[jpnjim]

I got these from a trusted Injector supplier, through Ebay.

 

The listing was for "87-95 4.0L upgrade injectors",

with a pic of orange head injectors like this:

 

 

They came very quickly, and were packaged nicely.

 

but they are grey tops, not orange:

 

 

I'll email the seller a question on this ASAP (used gf's ebay acct, waiting for her to get back),

but in the mean time,

can anyone ID these by their color?

 

 

They are Bosch injectors according to the auction,

but since it doesn't list them as Ford injectors, it's possible they are Chrysler Neon's, or something else.

 

My understanding is the Grey Fords would not be an upgrade over any 4.0L injector.

 

 

Ford injector list on NAXJA:

Anyone?

 

I'm hoping for a little better spray pattern + ditching the original leak prone 2-piece injectors on my stock 89' Renix 4.0L.

 

Thanks.

The flow sheet that came with these listed them as 210cc @ 43.5psi, High Impedance.

 

number on the body is 280 150 917

I can't ID them but they do have four ports instead of the stock single ones. I purchased these exact ones and they seem to work well.

Awesome, thanks. :cheers:

 

I'm searching the PN now,

so far it looks looks like the turbo guys use them,

a good sign I guess. :D

this site:

 

http://www.fuelinjector.citymaker.com/F ... Rates.html

 

lists Bosch 0-280-150-917 as:

18.25 LBS/HR

191.8 CC/MIN

138 GRAMS

43.5 PSI

3 BAR

 

 

Not exactly as listed,

but the above link also says:

"This list is only a guide to help with the selections of fuel injectors, So far it has been very reliable and the flow rates seem to be very close to what we find when fuel Injectors are cleaned and tested. However we are not the original creator of all of these flow rates and have found a few that needed to be adjusted to be more accurate Please let us know if you find any discrepancy with any purticular Injector number and we will do a flow test and change any information found to not be reliable or true."

 

 

This site also shows the 280-150-917's as 18.25lb/191.8cc injectors:

Still looking.........

[mnkyboy]

They look like 19lb injectors from a 3.8l ford, probably windstar or tuarus

Thanks!

 

Lol,

I'm finding out how much I DON'T know about injectors today. :yes:

 

 

Looks like the stock Renix injectors are rated anywhere from 18.5lbs to 22+,

this page kind of sums it up:

http://www.ausjeepoffroad.com/forum/sho ... hp?t=92236

 

"black "RENIX" injectors are stated in a number of places on the web as having a flow rate of 18.5lbs/ hour.

However when coas tested them on a professional injector test bench he got figures of 22.8lb/hr@43.5psi(240cc/min @300kpa) which would flow about 21.5lb/hr@39psi."

 

These grey Fords seem to be rated at 18.25-19lbs/192-210cc depending where I look. (oops they are not Fords, more below)

 

This is for a stock Renix 4.0L, so I'm looking for a better spray pattern, without leaks

more than I am looking for max flow,

but I am still interested in knowing what I bought.

Even at 18.25lbs/192cc's they'll probably take care of my Renix 4.0L no problem,

but I'm not sure why they would use a pic of an Orange (presumably Mustang) injector in their Ebay Ad.

 

Also, the flow sheet list I got with them lists all injectors at 210cc @ 43.5psi (3 bar), not 192cc

 

I still hate to complain, since I got these for a very (very) good price, very (very) quickly shipped,

and they should work well in my application,

 

but I'm gonna dig a little deeper anyway....

 

 

 

 

fiatslug87,

I'd rather not mention the seller's name,

but did you happen to check the part number on yours?

 

Thanks,

Jimmy. :cheers:

[fiatslug87]

I just went out and checked, same PN as yours.

Thanks,

that helps.

 

At least I know they sent the ones they had intended to.

 

 

Did your MPG get better?

How about power, better, worse, or no noticeable difference?

 

 

 

My biggest concern is if these 'upgrade' injectors are only rated at 18.25lb @43.5psi,

they'll only flow 17.3lbs @ our 39psi.

 

Compared to stock Renix 18.6lbs & 91-95 HO's 21lbs @ 39psi.

(they list them as fitting 87-95 4.0L's)

Can't really say, they're in a new engine.

Well,

I FINALLY installed these injectors last night,

and things went LESS than well. :(

 

I've swapped injectors before, so there was no issue with installing them.

 

When I started the engine afterward, it did not want to catch & run.

 

Finally, it sputtered to life,

at first seemingly on 2 or 3 cylinders,

then it slowly got somewhat better, but skipping & doing the shake like a paint mixer.

 

I let it mix paint for 5 minutes, till I was satisfied it would not improve,

then pulled the injector plugs one at a time.

#1 good (engine ran worse when pulled)

#2 no change (engine ran just as crappy, but not worse)

#3 no change

#4 good

#5 good

#6 good

 

I tapped the #2&3 injectors with the back of a screwdriver, in the hopes they would 'kick in'

but no such luck.

 

I then cleaned 2 of the old renix injectors, and installed them in the #2&3 locations.

viola, engine instantly back to its old purring self.

 

At the time of purchase this injector supplier said he would replace any defective injectors,

my next step will be to contact him & see.

 

I'll update again then.

[jpnjim]

I contacted them about the two non working injectors tonight.

(would have done it sooner, but moving has taken up most of my time lately)

I'll post up results.

[mountainman]

Never an update eh?

[jpnjim]

I never heard back from them (Precision Injectors)

I messaged them through both Ebay, and their web site...

 

I ended up pulling them out and putting the stockers back in.

[ftpiercecracker1]

Just go to the JY and pull two sets of Ford orange top injectors, they are the four hole. I got mine from two separate ford trucks that had the 4.9 inline six. I've had mine for almost a year now without a single issue.  :thumbsup:

[jeepsouth]

I've ran the ford orange tops for a couple years now ,and no issues to report here. I did not notice power ,or mpg increases just a smoother idle.

[92tanMJ]

I run neons in mine and no complaints here. Picked mine up at the upull-it and rebuilt them for like less than 20 bucks.

The two bad ones I had wouldn't make any noise when i hooked up a little 9v battery to them,

 the ones that were functioning all clicked when I connected them.

 

You could try each one, one at a time, and see if they respond or not.

When I finally cleaned out my old ones, I used the same little 9v battery to cycle carb cleaner through them.

 

It doesn't take much to operate the solenoid in them.
