Hey guys, I am finally putting my build together and im having a problem with my injectors on the weiand stealth ram intake. Before i bought some new injectors i read this thread:

https://www.thirdgen.org/forums/alte...ails-cant.html

So i bought some ford red top 30# injectors... the F1SE-E9A
but just like in this thread, they dont fit...

https://www.thirdgen.org/forums/alte...ve-fuel-6.html

Has there been a fix for this?? It looks like in the first thread, the guy with the 30# injectors has the actual holley intake.

Along with another guy ive read about having this problem, my rails are too high for the bolt holes, but i thought the red tops fit? are the weiand injector pockets different? i dont believe im doing anything wrong, im pushing the thicker part of the body on the injector right into the intake.. cant push any farther.

hopefully someone has an answer for me.. thanks

 

they should fit... how are you installing them? Into the rail or the manifold first?
Are they too short or too long? They are a standard length injector and are shorter
than the stock, so once again they should fit. Did you use the clips?

 

I have the Holley intake but weiand and Holley are the same manifold i believe. I run Bosch injectors with the Holley fuel rail so it may not be apples to apples here but the mod I did should work for you. Where the fuel rail has holes to bolt too intake I had them slotted straight down so it looks like an upside down U instead of a hole. I also relieved for the Allen bolt head. This way I can put the bolts in the intake and just drop the rail with injectors straight down. It also allows adjustment for different injector length. I had to put washers between the rail and manifold too so the injectors are better aligned with the injector bosses. The slots make this easier too.

 

I noticed they were shorter than stock, ive tried installing both ways With no luck. And yes ive used some lube to help them slide in. The part of the Injector that gets real fat on the body bottoms into the intake itself. No clips were not used

 

Thats interesting, I was thinking about something like that, im assuming no fuel is traveling in the path of the "U"? I might have that donee, it would definitely solve the problem im having, thanks for the advice there!

 

The Bosch injectors are a little shorter than multi Tec injectors, about 1/8". No the drilled port in the rail is above the mounting hole in mine but you'd need to confirm if yours could handle it. I insert the injectors in the rail just far enough to get the o ring fully in the rail but not "all the way" or bottomed out. Then when i insert the assembly into the manifold I wriggle the injectors until the bottom o ring is in the bung but again not necessarily bottomed out. They are sort of floating there. But they can't move up or down enough to unseat an o ring. I've not noticed them to move any.

 

sometimes with fitment issues, we recommend installing them into the intake manifold first and then the rail...works like a charm, however Not sure if would help in your situation but it's worth a try.

 

Thats some good information, thanks for that.
Any other advise is much appreciated ill grab any bit of information I can wrap my mind around when doing this sort of thing.

 

Yeah I dont think its going to work with the red tops, I might have to either modify the rail or pick up some new injectors.

 

ok so i attached some pictures to help show whats happening. I got some ev1 style injectors, and still having problems fitting them. First i replaced all the o-rings and it gave me a little bit more room, but still not enough. On the drivers side rail i got it bolted in (barely). The injectors are very snug in there, theres no moving room whatsoever. The reason i got the drivers side in was i tried removing the top o-ring and sliding it a little farther into the rail, and it worked kinda. Passenger side shows both o-rings in place for the top of the injector and i cant get any more room than that. Ive lubed and pressed, even pressing them individually into the rail doesnt give me any more room.

So heres my question, does it all look ok to you guys? it kinda makes me hesitant because of how tight it is and if i should run without the top o-ring? theres no other way i can get them in there with both o-rings without modifying the rail. but it looks like i might have to modify it. What is going on here? i cant be doing it wrong because the injectors are slammed into the manifold and im compressing the fat o-ring on top with no luck. BTW without the smaller o-ring, the injector can barely slip into the smaller hole in the rail.

let me know what you guys think, im dont messing with it tonight but would like to pass this step and get closer to running the thing, its only been 1.6 years since its ran

 

for some reason it wont let me add the pic of the drivers side rail..

 

The "top" o ring looks strange to me. I've never seen that and can't imagine why it would be there. Regardless the alignment issue with the holes in the rail not aligning with the holes in the manifold is exactly what i experienced with the stock injectors and why I slotted the rail holes. My Bosch injectors are shorter than the stock ones and presumably yours. Otherwise my Bosch look just like yours. I prefer to not put the injectors in a bind so they should float somewhat. I would either slot the rail or get different injectors. Also be aware of binding from the front view. When the rails are tight the centerline of injector should be centered with the manifold bung. The rail tends to pull the top of the injector towards the center of the engine. Yours may not be a problem but you should check it. I added washers between the rail and manifold for this reason.
