Ok gents. In the planning ahead here...... Im looking at 42lb injectors. Racetronix are out of the question cause they cost too much. Even with my cost. SO. Accel, Holley and Fords SVO's. I havent really done any digging to see the size differences and all. But im sure one of you guys have used an injector other than the RCX. I know my fuel rail may have to be shimmed up a bit and the plugs have got to be changed. That doesnt bother me.

Ok, chime in.

 

Why not the 8.1 marine injectors?

 

Because I can get the above vendors injectors a hell of alot cheaper. I want to see what else I can do before I spend on the 8.1 marine shooters.

 

I went with the Ford green top 42#. These flow at 48# at our rail pressure. It's like getting the extra 6 #'s for free Have to change the clips. Got those for about $15 online. Grab some heatshrink and solder and youre done.

 

Dam, so thats all you had to do?? no rail shimming at all? Where did you get the clips and plugs? Have a pic or 2 I could peep? Ive got a Ford Motorsports catalog here and all im seeing are orange tops. Wonder whats the diff?

 

Well, I have a Radix. I already had the rails shimmed to fit my goofy flex fuel injectors. On the Radix its easy. Just find the correct bolt length and use bushings or washers to space it out. It will take a little trial and error. I took the whole damn radix into the hardware store with me Stuck it in a buggy and shimmed it in the aisle. Then paid for all the parts. I ain't scared.

 

Thats cool. I think im gonna give a set of the FMS injectors a shot. But im not using a Radix. Any special place to get injector clips and plugs guys? Speartech maybe??

 

What exactly is our rail pressure? My shop manual says 55-62 #'s.

Last I checked it was 54.

 

Mine sits between 50 and 52. And thats with a new fuel filter and a 255lph inline pump. This is at idle of course. Goes to 62 at WOT. The Ford injectors are rated at 43.5psi rail pressure.
