i don't trust the spacers that came with the kgparts fuel rails. they fit loose and are not a press fit and i don't trust them. i've seen some other threads and ways to fix this ie using a rubber hose. i didn't like that either. i decided i'd make press fit bushings and some spacers to go along with them. i'm posting a drawing if someone else wants to make them as well. I can machine a set of 2 for $25+shipping.

 

There are hundreds of people running the spacers that come with that rail and no problems. I wouldn't worry about it.

 

like jason said, we install them on tons of cars will no problems. but i do like the idea and the work thats in them.

 

why did my primary ones fit so loosely then?

 

id be interested in a set of these for the primaries....
