hey,
I just intalled a aem fuel rail on my d16a6
It is leaking a little from the ends, where you plug the rail at the end and at the fuel inlet on the passenger side.
My question is; How tight do these have to be, I don't want to break the threads or anything. I tightened them a little more and it leaked less, but it feels real tight.
Anyone have experiance with these. They feel real tight already.

 

Did you use any type of sealant on the threads?

 

I thought about it, but they only recommend using the crush washers, and no type of loc tite or anything, maybe I'l' do it anyways

 

I had the same problem when i installed my fuel rail in my prelude.
I used the washer supplied by them and it leaked, then i used my stock one and it stopped leaking...

Try using the stock washer that was on your stock fuel rail, if it works leave it or get a new one from Honda....

 

use some teflon tape

 

teflon tape on a banjo fitting?

 

still a fitting still has threads its plumbing

 

I believe using teflon on a fuel fitting is pointless because telfon gets eatten away by fuel like acid eats flesh. Try reusing the OEM washer if possible.

 

It's leaking on the other end. teflon, probably not, maybe blue loc tite, and a lil more torque

 

not sure you want to do the blue loctite on the fuel rail.

As far as I know the rail is aluminum. Not good to put loctite on aluminum unless you are never gonna take it apart.

loctite on aluminum and threads will cause you to remove the aluminum if you pull the threaded part out again.

We never used loctite where I use to work with aluminum due to that factor. you would kill the part.

Use either teflon tape, thread sealant (ptv) or factory crush washer.

 

Technically you aren't supposed to reuse them,
But an OLD oem washer is usually better
than the cheapo ones they supply you..
