I broke one of the lines at the injector on my '84 SE. It is the one that goes to the rear intake injector. It looks like they are no longer available.

Will S4 lines work on an SE?

 

For right now I'm just going to go with a set of used lines.

The future:
RotorSports oil metering pump lines

I emailed them: "We have SS OMP lines that fit the 2nd gen RX7's- these are made to fit all FC RX7's and are made slightly longer than needed so they can fit all versions (S4 N/A & turbo- S5 N/A & turbo)
The lines can be trimmed to fit all versions as well as the GSL-SE. One end of each line is unterminated & includes the banjo fittings that can be attached easily once lines are trimmed to fit (or you can terminate the ends & re-route the lines)

Cost is $190.00/set of 4 SS lines & fittings + shipping"

These would fix the problem permanently. I have a friend with these on his FD.

 

would be nice if SS were available for the 12a.

 

Not really. The ID of the lines needs to be small for capillary action which holds the oil in place instead of letting it bleed back down leading to dry starts every time.

How long do you think it takes for air to purge out of OMP lines that are empty? Or how about only half empty? It takes a long time. I'll stick with the OEM lines whenever I can.
