What year and motor Ford 19 lb injectors fit the 2.5? I have some orange top 4 hole 19 lb injectors from a 97 4.6 mercury grand marquis (EV1 type) - tried fitting them but they don't seem to fit in the intake, are these the right ones?

Thanks!

I'm not sure about those injectors, but the ones that i used on my 93 2.5L were for a ford mustang 5.0L. If i remember right, they have a bright blue top cap on them.

I thought you could use 19 lb 4 pin Ford injectors from a 4.6 or 5.0? The pintle cap seems to big unless I am mistaken. Not sure if I have to modify something or if these should just push in and be done??

The red is obviously stock.

They just push in but kinda a biotch to get them to seat. They kinda click in... like ull feel them seat down in there. Took me a while but I used the same ones u have

Thanks AZdevilYJ - should I put them in the rail and then the intake or visa-versa.

I put the bottoms in first I believe. U want to be careful not to damage the o-rings. This mod is Such an improvement! Ur gonna want the 4.0 throttle body to get the most outa the injectors.

I have the 4.0 T/B already and a few other goodies. lol I will try and fit them again they just didn't wanna seem to be seated in the intake... Maybe once I bolt the fuel rail down it will hold them in place. Thanks for advice - hope this works

 

[AZdevilYJ]

Haha I tried that method and sprayed gas all over the motor. Just push hard and wiggle em. They'll fit with a little elbow grease. Good luck!

The yellow ones in the picture look right. I can check my part number when I get home but I pretty sure those are correct.

 

[jeep30]

Yeah I can fit them in the rail but they don't seem to wanna seat in the intake unless I'm expecting them to be super tight in there. lol yeah def check if you have time man, I just wanna make sure these are the right ones. Problem with putting them in the rail first is then trying to push them all at once in the intake evenly. But hey I'll try anything lol

 

[jeep30]

Well, put them in the intake first and then the rail went on so they seem pretty good. Guess I'll find out when I fire it up. Thanks for info fellas

 

[AZdevilYJ]

Sorry for the delayed response! Works been hectic. How'd it go!?

 

[jeep30]

Not sure yet, seems good now though. Decided to go new manifold, fuel filter, ccv, etc while apart. Gonna fire it up next week once I finish the electric fan mod.

With the bigger injectors do you need to do an adjustable fuel pressure regulator also?

 

[AZdevilYJ]

No its only a boost of a couple lbs. The benifit is the 4 sprayer holes a
Vs one on the stocks which atomizes much better in the cylinder, and that extra couple lbs helps it run a bit richer since the 4cyl are lean from the factory.

I just heard of this today talking to another guy from Jeep club, can you tell for sure what you used on yours to get them in the 2.5l?

 

[ddferdt]

I did this mod a while ago, noticeable difference. To make getting them in a little easier I put automatic trans fluid on the o-rings. Used ford 5.0 yellow tops

Better millage and response out of it?

Haha mileage. Response was definitely better. Coupled with the 4.0 throttle body this swap was worth the money
