Does anybody use them? I have them, both upper and lower, but I´m having
problems with installing the injectors. I have been in contact with Keith, but
we haven´t been able to solve the problem, so I thought I post here...

Thanks Oscar

 

Keith as www.kgparts.com?

I thought those were FD only rails...

 

He makes them for the FC also! Very nice quality, and Keith is very helpful!

 

Good to know, I might have to incorporate those on my setup

 

I belive DigitalSynthesis has them and had problems using KG primary rail, ended up using stock primary rail.

 

Oscar, I still would like pics to help you see what you may be doing wrong... Thanks

Knonfs, yes I have FD, FC, RE and 20B (finishing up 20B's this week)

 

I dont recall that being the case. I just contacted him to verify that it was not the case....

 

I have sent you pics! Haven´t you got them?! I really need to get the rails hook up ASAP cause rest of my fuel stuff would be here any day now...

 

So, what is the problem? bore size, depth, rail height? It's a pretty simple part, what injectors are you using, and are you sure the O-rings are correct? Sorry, but you are pretty vague about the problem, makes it hard to help. Carl

 

I think it´s easy to fix it, but I have never before installed any fuel components what so ever! I can fab up new spacers for the LIM and the block but I need to know how a proper install should look like...
I´m going with bosch 1680cc injectors all around (I know they might be to big for primary), and the problem is that the injector doesn´t seal against any kind of sealing, like an O-ring or so. There is O-rings on the side of the injectors but none between. And the spacers are either to long (block) or to short (LIM). This makes that the injector sits lose, and I´m able to move it up and down between the mani and the rail.
So the bottom line is that the distance between the rail and the mani/block is the problem, and I´m a little worried about that there´s no O-ring between the injectors and the rail and mani... Don´t want any leaks!

I must say that this is most likely a problem caused of my lack of fuel install experience, and I can REALLY recommend these rails, super quality!

Thanks!

 

4 1680's? Damn you will have one firebreathing beast. Is this going to be a street car or all out drag

 

Mainly street, I know it´s a bit overkill and I´m considering to go with around 900 on the primaries instead...

 

Yah I didn't tell hIGGI the whole scoop. Was not problem with Keith's primarys, but that he had originally designed the primaries to require injector spacers in order to fit the best. I did not want to use spacers, so I declined to use the original design of his primary rails and instead opted for his Secondary rail which, I must say, KICKS ***. Keith was superb through the whole process, and it was a mutual decision for both of us - he took initiative to let me know in case it would be a concern (other vendors should do so well!!) and was very responsible with the whole transaction. If his primarys are as good as the secondary rail I have, they are bound to be superb. Anyway, I strongly recommend his products, and that's my final word. Given the opportunity in the future I will buy from him again, absolutely.
