Frustrated over injector swap
So I got a set of Bosch F78E-A4A form an eBay seller that said they were an upgrade for the 91cherokee 4.0. I assumed these were the ford #19 yellow sticks but now I'm not so sure. I have searched till I was blue in the face and cant find the flow rate for these to make sure they work. So are these the#19 or are they different and has anyone run these or have anymore info on them. The numbers stamped on them are F78E-A4A and 9F593 on the other I just need their old pressure rating and their static flow so I can do the conversion. Any info will help thanks.

I read that they were from a 98 Ford mustang 4.6 on a website but when I tried to look it up by searching 98 Ford mustang injectors nothing came up..

I have the ford 19lb injectors in my jeep and they look exactially like the ones he bought. Part number also sounds the same but my jeep is almost 3 hours away so i cant really confirm that.

I'm not sure of the part # but a while back I bought 4-hole ford injectors off eBay, they looked similar to the ones you posted. I bought them without much research because at first I thought they were Chrysler ones, and I got em for $50.
They worked fine. Still in there.
I'm going by my dads later I'll check the numbers on them, they're a little rusty though lol.

So it looks like we both have the ford 19s just different versions, I have the explorer version whereas you have the mustang ones. Hope this helps
