I ordered the Victor Jr. with the rails and NOW notice they are 3/8"......not 1/2" or -8 ports.


My fuel system is designed with dual -8 feeds and I am not sure how putting 3/8" to -8 couplings on them will affect flow. My Fuel Lab FPR also has -6 ports.

1. Will it be okay to run the rails and FPR with adapter couplings on them or do I NEED to upgrade to -8 parts?

2. Are there even any rails out there that are -8 and bolt onto the Victor Jr.???

The system will need to flow 1300 whp.

hey man i have asked this ? before and was told they would good for 1500 plus hp, i would wait for others to chime in also maybe some first hand experiences

You will have no problem with them 3/8 pipe is different than 3/8" its about the same as -8 size wise.

Just use teflon paste on the treads.

Be sure to check if they are pipe threads or straight threads. If they are pipe, then use a small amount of teflon paste. If they are not pipe, then you dont need paste... they are meant to use an o-ring. I am running the FAST aluminum fuel rails (red ones) with my Vic Jr and they are not pipe threads. I needed a fitting that was AN-to-AN with an o-ring.

Just didnt want you to **** up your rails.

See the difference?

Thanks Nate. Same with the -6 fuel lab FPR? It will suffice?

Use Never Seize on the threads as it is a pipe thread and it seals on the taper... U dont want to strip or gauld the threads up, had a couple buddies mess there rails up not using never seize!

No they are O-ring fittigns and seal with an O-ring. The rails are pipe thread and need sealant. Antiseise is not a sealant.

The NPT threads are designed to seal at 75% thread depth, if u went to machinist school u would know this... it does not need sealant, unless ur threads are jacked up then u could use sealant but i would get another fitting and or chase threads....

if it leaks it wouldnt be air! this is fuel...i would and have always put paste on my threads. thats just for me though, not someone elses car. i have never had a problem and im betting nate hasnt either

Everyone has there own way of doing things and that is fine, in my many years in this business i have not had to use paste except a couple times if the threads were tapped too deep and wouldnt seal.. i just gave some advice earlier and he called me out on what i said and his statement is not true, the threads are designed at 75% thread depth to seal themselves.. Call any machinist and he will tell u the same, but none the less either way shall work not trying to start a pissing match here.

The fact is that NPT threads should not require sealant... but fuel rails are often a problem due to the thin walled nature of the extrusion.

If you cannot tighten them too tight, they may split. A little sealant never hurts if done properly. Better safe than sorry.
