I contacted BBK that I have a set a fuel rails from them and the little end cap with the O ring leaks at pressure. They responded with "Sorry to hear that you have a leak - we would recommend trying a slightly larger O ring at the end under the disc." So, super helpful, thanks BBK. Has anyone struggled with this problem. Looking around I have seen some mention of it but nothing solid as to what worked. What O ring was used to complete a solid seal? Is there another end plug out there that works? I really would like this to work and not have to swap rails.

Thanks for any help and/or suggestions.

have these rails on my built motor. remove the cap and allen head bolt. drill it out. tap it for a plug. put in plug with some sealant on threads. be done with it forever, ive had 0 leaks and it is the best thing you can do. problem solved.

BBK is sending me a few O rings to try out and see if it solves the problem. Here are the part numbers and I will take pictures of the packing when I get it. Hopefully it works and this helps someone else out as well.

CHD254 – 1pc

SCP217 – 2pc

HDW229 – 1pc

I like the pipe plug idea, less likely to leak later on.
