I just wanted to know if anyone has done this combo before. I have the fuel rails and 4 725 ID injectors. On Rising RPM's website they say that the rails needs to be shimmed to offset the injectors length. They recommended a website to buy the shims, but when i ordered them, the website only shipped to company's and dont do private sales. So has anyone ever ran this combo without the shims?

 

you need the proper hats for the injectors(11mm hats).
Get new grommets for the engine side of the injector and it will fit snugly on the injector.
I got the 1000's in the primary spot and they fit fine.(2000 in the secondaries),that is with the RisingRpm rails.
are you running aftermarket Ecu too?

 

rtek 2.0 so far. I have the proper hats, its the 11m blue ones. And i think it comes with the grommets for the engine side. Youre talking about the black rubber spacer looking things right?

 

Yup.
The Rpm rails come with a little washer like spacer.
I didn't use that.
You do however still use your plastic oval 2 holed spacer to the engine on the primary spot.
