Old guys with 12As club meeting
As I understand it, the conversion, R-12 to R-134, would require flushing the system and /or replacing all of the seals because the old R-12 and its lubricant is not compatible with the new. I'm not sure. Can anyone who has done tell me what is involved in doing it yourself? I do not want to burn up my compressor.
Simply adding a can of R-12 or a suitable substitute would be far easier. Who might carry a substitute for R-12?

just got back from the volume test. 1/8 gal. if that. Don't have time to do any more testing right now, but next thing to test would be before and after the inline fuel filter, right?
Waffles - hmmm good

Thought I'd look local before buying online. I'm looking for a 82-83 12a rear rotor.
The front rotor is a C weight. So anything close to that would work.
I'll be at Crits Lakehouse meet next weekend and of course zoomfest. If any of
you OGTAers have one of these maybe we can avoid shipping by meeting up at
one of these events.

Yep. I would repeat the test at the pump outlet or filter inlet. That way you know if the problem is before or after the pump. My friend who had the problem only got maybe 10oz when he did the test. Just enough fuel was getting through the system for idle and nothing more. Some other things we noticed with his:
- although the pressure was okay at idle, the pressure would slowly built to the correct pressure instead of jumping up the the correct pressure like it should
- due to the blockage, the pump was making much more noise than it should
Another friend also had this problem, but was not as severe (it was about like yours). It would drive okay, but start to cut out at higher rpm/load. He had already dropped and cleaned the tank, but it turned out there was also a partial blockage in the hardline.

By the way, if history is a good predictor, it'll take Tim forever to ask for his A/F gauge back. It's kinda cool to see how far you can go down the road on a cold start before it goes into closed-loop mode. If you keep yourself in some good vacuum going down the road, you can even watch it sweep as you go. It's like being Michael Knight for a day. Keep it plugged in and play with it while you can, and just hide it when you know he'll be around.

Must be atmospheric, I'm getting some fuel delivery issues too, the Silver One hesitated a couple times today on the trip into Atlanta.
Time for a new fuel filter.
Tim post some photos of the mounted wheels at least. Any chance of seeing this thing at Crit and Dena's Lake House Event?

Haven't looked at Jeff's car.
Not sure on the lake house. I would like to make it, but I'm heading to mexico next week. Not sure if I'll need to get stuff done beforehand.

Anyone know what size wheels studs I should be running? Too lazy to go downstairs.
12x1.5 in a 2.25" length sound right?
And it's 60 degree conical for the nuts, right?

You had me worried there Alex, it would have taken you the rest of your life to pay for that thing, never mind the insurance. Good to hear you are still with us!
So if it isn't a rotary, why do they call it an "R"8? Are they trying to cash in on RX-7 name recognition?

Just got done testing the fuel volume before the filter...so, dying fuel pump?

and if anyone is so inclined, the oh so riveting video. you can hear the FP groaning away. camera (iphone) is propped up against the driver side wheel.

That doesn't look like enough gas, delivery in a GSL is way more than that. Also it looks like it's pumping a lot of air, you can see the air bursts peppering the surface of the gas.
Certainly looks like the pump is worth replacing.

Damn, that's right at the outlet of the pump too, huh? I'd check the inlet just to see if you have a cone filter in there that's jammed up. It's inserted into the steel inlet to the pump. There's still a chance that the screen inside the tank is the problem. The easy check there is to drop the pump, leave it plugged in, and pump fuel from one jug to the next. If that test is just as shitty as what you just posted , then you know it's the pump.
The Bosch pump is what I use, though it's a little loud. I've also used the Airtex pump before, and it's quieter.
