Problems with KG parts rail

[Timmy]

Has anyone else had problems with them?
Jason (super7) fitted one on my car and it leaks, i trust him on this fully but rx7store really don\'t seem to care and think there is nothing wrong with them. But after some research it seems many have had problems with this rail.

If it\'s leaking on from the injectors because they are not pushing in far enough, I have found that by leaving the small alen bolts on the rail loose but fitting the feet bolts tight onto the rotor housing then pushing down on the middle of the rail and finally tighten the small alen bolts cures this "fault"

Yeah i saw jason screwing about that rail! I was there 2 days in a row and he couldnt get it to stop leaking!

I dont believe there is a fault. Depending what injectors you are using, you need to use the spacers he sells, I\'m assuming you havent.

When you say "But after some research it seems many have had problems with this rail." - is this on RX7club? Keith\'s fuel systems used to get excellent write ups on there, may be some thing has changed, its a while since we dealt with him.

Dont really need to stress how important properly seating injectors are. They *do* lift if they dont fit properly and will leak fuel - about 12 inches from a 1000 degree turbo housing!

HTH Tim.

Hey Rich, thanks for pointing me this way.

Not sure what the problem is or where the fuel is leaking from... just saying that "it is leaking" leaves a lot of possibilities..
People "mess-up" installing all the time. It could be like Clive said and the injectors are not in all the way. Someone else said they messed with it for 2 days??? if you are messing with taking injectors in and out trying to solve a leak, I can only assume that an o-ring was torn, maybe more than once, takingn them in and out. If it was torn even slightly, you are right... you will NEVER get it to stop leaking.

Although you seem to have purchased them through rx7store, we (KGParts) could also have been contacted.
If it make it any easier for you, we have a forum on our site where you can post pictures and ask questions just like here.... but right to the source. here is a link to our Mazda section. Please feel free to sign up and ask away. http://kgparts.com/forums/mazda/
Only reason I am saying to post it there is that I dont have time most weeks to search through the hundreds of forums we are on. Only reason I saw this was that Rich from REWorx pointed me in its direction.

Hey Keith

Whats the deal with the ally spacers, what injectors require them? I seem to recall we used to use them, but it was a while ago and i dunno what injectors we\'d ahve been fitting at the time.

Thought it was worth giving u the headsup, our experience of the kits was only ever good, so hopefully Tim can get his kit sorted out with your input.

I have these, and can\'t say that i\'ve noticed them leaking. But I haven\'t really checked them thoroughly: whereabouts do they leak?

[Timmy]

They sit in the rail fine, but once under boost ie the fuel pressure and duty goes up they start to push themselves out of the rail.
Jason rang another rx guy and asked them if they\'d problems with the kgparts rail and turn out that they had (not sure if it was the same prob or not). Either way this rail has problems whever it is a one off or not and as a result is no good to me.

did he fit the ally collars into the inlet manifold

if not re-worx sell them for around a tenner

[BlitzBoy]

yep the alloy collors are very important

[Jit]

yes those were fitted

[BlitzBoy]

hmm maybe the brackets holding the rail down may need modifying then shave a few mil off the base of the brackets so the rail seats further towards the injector holes, or the holes on the brackets moved down to produce the same result of a tighter fit
Remember these cast stock LIMs wont be all the same.
Or use Gary at Rotaryarts his fuel rails of a different design but will let you use the 1680 top feed injectors

Anyone using the KG parts rail who haven\'t had problems?

[BlitzBoy]

I never had problems, had three different setups as well been perfect all the way up to 1.4BAR, and now using it on my cosmo LIM and its dry as a bone

cool :Thumbs-up... just wanted to check as I have one of these waiting to go on
