Fuel rails.

Recommended Posts

I have a hks fuel rail with hks 1000cc injectors and its a pita and keeps leaking.

 

When i look inside the rail it has a groove that the injector ring sits in but nothing at the bottom for the injector to pull into.

 

If i over tighten it the injector ring pulls past the groove and it leaks.. same if i under tighten it.

 

I get it all just right and when driving a few hundred miles it must vibrate and move the injector and it leaks again. its a royal PITA

 

Has anyone else had this trouble with the HKS rail? i just dont understand it.

 

Anyone got a pic of the inside of a boostlogic rail or any others? i want to see if there is a lip at the bottom that the injector pulls in against.

 

Thanks for any help Jamie:)

I've never had any problems with my HKS rail and HKS injectors, they've been on for over 5 years now.

 

me either. The only issue is the small neck size restricting injector selection.

 

Jamie, are you sure you didnt pinch an O ring fitting the injectors.

Ive had it out 3 times now and all the o-rings are perfect.

 

What happens is the oring on the injector sits in the groove in the rail.. when i fit the rail and tighten it in it weeps alittle at the manifold end... if i tighten it to much then the oring pull past the groove and it pisses out.

 

What im wondering is if the boostlogic rail has i lip to stop the oring pulling past... then in that case i can tighten it down with out risking it pulling past.

is it not possible to simply use a larger o-ring?

 

i'm afraid that's about as technical as i get :D
