1988 4.0L Injectors?

[Habanero]

Does the 1988 4.0 L have 19# or 24# injectors?

SHould be 19# for the AMC242, all the way up to current.

Why for do you ask? The ECU has limited ability to adjust injector pulse width - you could probably get away with 20# or 21# on a stocker - to "fine-tune" fuel mix, but going to a 24# squirt would be just a bit much...

Four of the six of mine are "leaking" and I have a set of 18# out of a 5.0L mustang that I thought might work, I just was trying to confirm what they are suppose to be. I have a set of 24# that are available but they obviously will not work.

[Saudade]

They're 19#. Are you sure the set from the mustang are 18#? I got a set off eBay that are 19#. What color is the top of the injectors?

[Habanero]

Orange

I was running the yellow top mustang injectors for about 5 years when my jeep ones started to leak. Worked great, still got 20+ miles per gallon.

I have orange tops on my '88, they are 21lbs. off a 4.6 ford. works great. I assume thats what you have there. good luck.

Stock '88 injectors flow 18.6lb/hr at 39psi so the 19lb/hr orange top Ford Mustang 5.0 injectors are a direct replacement.

[Saudade]

Mine are the orange tops.

[Habanero]

Good deal, just put them in and everything is working great, thanks for the information.

I think mine were yellow tops actually, I bought them quite a while ago, but they were also 19 #/hr ones.
