I'm working on some fuel rails I came by as part of a large used parts purchase, spent today bending and straightening the abuses of prior owners.  One of the rails is different - it is at the front of the group pic.  This design also matches the OE rail on my car.  So... a question for the knowledge folks: was this design unique to early cars - those we refer to as Series 1?

Next up: the dreaded and tedious cleaning process to get rid of years of grease, grime, rust, ...etc.

Hoover bag shows it on VINS ~ 12,000 but not on ~18,000 so somewhere in between it changed. This gives  a change between Oct to Dec 1970

My 7/70 and 10/70 240z cars have this version with the tab and hole. I have no idea, what was the hole for.

I've never seen photos showing anything mounted there.

Jim A.----care to do a 73 fuel rail as you prepare these for plating?? The one I have is certainly restorable----just kinda grungy. It has captive plastic insulators that form a thermal barrier from the metal legs conducting heat from the engine mounts.

I'd sure like to send it to you and I'll cover the expense for its restoration..

JIm D. - I've got two rails for flat tops and three for 260Z yet to get underway, one more in the bunch would not be a problem.  Pack it up and send it this way.  You already have my address?

Here's another oddity to challenge the experts:

Working thru cleaning the rails for round top carbs, I came across this one with  both front brackets solidly fixed.  All others I've seen have one fixed bracket and one movable bracket - seen behind the odd one.  Note also the fuel line connecting points are equal length, not staggered as most.  The rest of the rail matches others.  Thoughts?

Hi Jim,

I looked at early VINS and the very early one in the Engine FSM. They all have the nylon support.  I think that rail may have been customized or perhaps from a JDM model.
