Well the shop tried to put my MSD 72lb Injectors on my AEM Fuel rail, and my stock Fuel Rail...Didnt fit, too big. Does anyone have any idea why they dont fit, or Do I have to do something special to make them fit. Please respond quick guys, I need to know what to do or should I just order some RC 720cc's ?

 

all you have to do is change out hte oring to factory green or brown oring on the top

 

my AEM fuel rail has been "made to fit" and was opened up a little bit with the help of a shop, or im sure Virens idea may as well work also...good luck

 

Thats not true about just putting new O-rings on to make the injectors fit. If they are REAL msd's, you will have to drill out the openings to make them fit...not too bad though for the savings.

 

theres two companies makign the msd injectos make sure to see which one. the seiemen deka ones are the ones that just need orings the other brand you have to over bore just like a boshc.
