Can thr 350 mm one be acquired anywhere?

My typo err. I meant the Z store (MSA) thanks for your information

Do you know the diameters of those wheels? I have used a 20 year old Momo that I like for size and grip but would like to find something that is more respectful to the early Z. The original is restored and tucked away for another day. I see Zstory has replicas

@HS30-H what can you tell about that steering wheel?

I did all my bulbs in the car except headlamps. Only needed the new flasher for the turn signals. None for the flashers.

I have this pump that seems work the way it’s suppose to. But this crack bothers me. is there any one who has tried to replace the lever? The manual implies it can be

You can get the bushings a Z car Source https://zcarsource.com/shifter-bushing-240z-70-71-new do not buy the metal ones on EBay you will hate the feeling . Be careful when you tighten the nut the chrome on on the shifter will mar easily.. the lever should be straight not dog legged. Let me know if you need photos

I think I have one I can send you? what year was your can manufactured?

@zKars Do you know if the check valves from the Nikki 510 pump are the same as the Nikki 240 pump? I noticed in the FSM that specified PSI for the L20 is different than the L16. Is it the Check Value that control that? Anyone?

Here is the link I saw recently https://youtu.be/-t6geNGbEXM

@zKars so I read rebuild post without the missing photos and have gather up the following: a used Kyosan Denki A new Nikki for a 510 a new GMB 550-8040 the current Spectra that’s on the car (about a month old) and a used 240 Nikki arriving in a couple days Looking for your suggestions on how to start to get a good combination? is the a way to bunch test each before opening them up?

I saw a video someone sent me discussing this same “fix”. Looks like a possibility if rebuilding the Spectra with parts from a New GMB and a new 510 Nikki pump don’t solve the problem. Currently waiting for them to arrive. We don’t have any high altitude drive scheduled anytime soon.

Do any of you experience with the Delphi or carter version fuel pumps?

So mine was running awesome until I was near the 5000" foot mark and then it just ran out of gas at the carbs. When it did start it ran fine both times. It feels like it is the mix of hot motor bay (engine temp appeared fine on the block sensor) and the radiator. Both electric fans were running and my speed was pushing hard on 15, 25, and 35 MPH curved for about 3 miles just prior. Of course it would be easy to adjust in a half turn (richer) in on those days. Thoughts anybody? Electric pumps? @zKars If the fuel pump you replaced in the last 30 days is a Spectra or GMB brand, then your issue lies there. Where do your get a manual pump that is not one of those two?

It is Spectra 241 87019 interesting because the name was covered by a white stick on label.

While searching the site for Vapor Lock I could not find any mention of the effect of high altitude. I have experienced what I think was “vapor lock” on my 240 that is running SUs with a manual pump (New in last 30 days). In both cases it was at altitudes of 5000’ and 4500’. In both cases shortly after spirited driving at higher RPM (4K-5K) and then slowing down to RPM of 2-3K. The engine would seem to run out of gas. Checking the filter showed fuel available. Fuel line from pump to carb was dry. 2 hours later and coasting down it started and ran fine for the next 150 miles home. In 25 years of driving a 240 I have never experienced this (Vapor Lock) before. Is it the extra engine heat by driving hard? The fact boiling temperature is reduced at altitude. Do electric pump cure this from happening?

One of the problems with old SUs is the butterfly shaft bushings get worn and leak. Z therapy replaces them with roller bearings instead of brass bushings. Good luck though and post up your journey.

Give me a shout if you need photos.

I got 20” from center. The 240 has a muffler hanger bracket directly above the outlet pipe of the muffler. I offset forward in the car to tighten up the exhaust pipes he makes. are putting on a resonator it made mine a little more pleasant. But still nasty on WOT between 4K and 7k.

Don’t know if these will help, hard to measure with only two hand a phone and a tape. I can try later with a micrometer. Let know.

I have wondered for a long time if these sales all close or do some fall through? Is there an out for the buyer? anyone have any knowledge about that?

Not really when out in the open. I couldn’t back it out of the garage as the gas tank is getting refurbished.

I cleaned the rust off and soaked in rust release chemical. I then used a chrome paint by rustoleum. Put in LEDs. I am really happy with them.

I am in the middle of a fuel tank refresh. Tank is out to Rad shop for cleaning and coating. Meantime I am checking my sending unit and gauge reading. Do these pictures of the gauge reading look right at max float and min float levels travel with the sending unit? what else should I do? Hoses are 4 years old. Ran a can of carb cleaner through the supply and blew it out. How many gallons does your tank hold?

I have used “Oil Eater” for years. You can order it through Costco in gallon Jugs or 5 gallon pail. Spray it on let it sit and then spray it off with water. Use a brush for hard spots. I also use Gojo on a rag on my engine bay.
