are all 19lb injectors created equal?

[1990LTD]

Are the ones living under the hood of my 95 any different than the ones I have from a Mk VII?


Would mixing the two sets up create problems? As in, I do my HO swap and find that one of my injectors is bad, can I throw in one of the 19lbers from the aero and carry on?

I just searched for your thread title

But that's not really an answer.
I'm curious myself, if explorer injectors and mustang injectors are the same?

something interesting that i found a while back.

for the trouble they are worth swapping out, i would just buy a set of rebuilt flow matched four hole injectors on ebay.......iirc around 100 bucks a set shipped.........that vic has been sitting a few yrs and not been run, i doubt the injectors are good

From what Ive noticed in the junkyard, the older aluminum intake aeros have the old style injectors, i think 96-97 they went to the skinny 4-hole ones.

good to know, I was going to use the ones I have from Pete (he got them from a Lincoln I think) and find a shop to flow test them for me before I put em on.

Later ones are 4 hole, and atomize the fuel much more better-like. They can be mixed and matched but if you're replacing them, the later style are superior. I found a video on youtube somewhere demonstrating the difference between the old one-shot kind and the later 4 hole. The early style shoot fuel in a nearly straight line like a garden hose. The 4 hole pumped out something that looked more like a cloud of mist, which is what you want in the motor.

they look the same though, don't they? Or will you actually be able to see 4 pinpoint holes?

I was always under the assumption that the older 19's were the fatties like the sock lopo looking ones but with the orange hat..the newer ones were much skinnier.

[BerniniCaCO3]

what are the symptoms of bad injectors?

[BerniniCaCO3]

did some more research: skinny ones are newer ones, and should still plug right in.
Some of the fat ones were 4-hole anyway; there were 3 generations of 'em, and gen2 and gen3 both were 3hole; just got to look up the part number I guess...

think i goofed on the video link may have added soemthing extra not sure

You should be able to see 4 holes.

[BerniniCaCO3]

Yup; just got mine in the mail today.
Guess the explorer ones I put in, were of the older style anyway. That-- or someone put mustang injectors in an explorer intake. When did they switch to the 4hole design?

I keep on spending money on this rebuild, but $75 for NOS 4-hole injectors, not sketchy-ass old ones, I think I'll appreciate it. Installing them tonight, hopefully not too much trouble.

What kinds of lubes are safe for the injector o-rings, to make them pop into the intake easily?
