Check that thread. Dont know of many people that might be doing this. But its about the 7139 Edelbrock intake manifold for LS-Based engines.

But as a general question... what do you do about mating these injectors into the intake. They are 8.1 Marine injectors, they fit into the rail fine.. but when i try to mate the bottom of the injector to the intake they seem like the only thing to hold them in is the tiny bit of resistance the o ring gives and the bracket i guess, im just worried that im missing something here.

 

I think you need to use car style injectors or lengthen the fuel rail brackets.

 

Are the car style injectors longer?

 

I figured it out... they sent me the wrong fuel rails. Dyslexia is a bitch, i'll tell you what, lol.

 

The car ones are shorter. Depending on the applications etc etc.

 

Oh alrighty. I've been trying to find a pic comparing the two style injectors, but no luck.

I'm thinking I am using the wrong fuel rails... I'll call Edelbrock on monday and see whats up. Thanks!
