Since I got the car the fuel gauge never worked. I had the tank restored by “Gas Tank RENU” I had the Z clinic shop in Austin install the tank with a new a sender unit. The fuel gauge still didn’t work. I had the radio/dash panel out which gave me access to the gauge. I grounded the yellow wire and the needle moved, I stopped at ¾ full (never pegging gauge). I read you can damage the gauge. I tested the wires with my meter. With the ignition on I got just under 11 volts at the gauge connection. I removed the gauge and cleaned the outside contacts. I installed the fuel gauge and it worked kind of. When I turn on the ignition the gauge floats constantly. First to near full, then hangs around half full momentarily, then near empty, then back up to near full. It constantly floats the range. Any Ideas - Thanks

I found this under my passenger seat in my 73 240z. Is this part of the seat belt warning system? If so how do you I reconnect it if I choose to.

Also looking for tire size recommendations.

I know a lot has been discussed about tires. I can't find any current discussions (since 14" started to disappear). I am getting my car running after 25 years (see: "1973 240z Awakening"). I don't want to upgrade wheels and tires now with all the future expenses coming. So from what I can find on this site my Choices are 195/70R14 (Stock), 205/60R14, 215/60R14, and 225/60R14. Can you go with 15" on this rim, if so what? -Thanks -

This weekend: Installed MSA exhaust system, 3 Core Radiator, new radiator hoses and new hoses all around, Slave Cylinder, Water Outlet housing, Rebuilt both carbs, still more to do next week.

Thanks, its a very solid car and the undercarriage is very clean. I plan to eventually go back to the original Red (110) the current engine bay color. It came with the rountops. The plan is to get the car running and then I will decide what to do.(probably keep the round tops).

I purchased this 1973 240z CA/AZ (one owner car) that's been hibernating for 25 years in a AZ. garage. I am working on waking it up. (See NEW MEMBER - NEW CAR Topic). Work started - Pulled the head, there was a bent push rod and a bad lifter. Sent head off for a rebuild (forgot to take a picture before installing). The timing chain was installed incorrectly in the past (180 degrees off) this would make the car run poorly (as you can imagine). Maybe that's why the PO parked the car in a garage for the last 25 years. The exhaust manifold was cracked all the way through, it couldn't be repaired so I ordered a coated header. Exhaust system from MSA TBC Coated 6-1 Header and MSA Premium Exhaust System. New parts installed - new timing chain, water pump, fuel pump, MSA 60 Amp alternator, and motor mounts. Exhaust came in last week, finishing up the engine and then starting up the engine / car for the first time in 25 years.

I am new and learning how to decipher the postings. When someone says SU, most of the time they mean SU-H (roundtops) Not SU-HIF (flattops) with Integrated Float, also the flattops have a "Anti-stall fuel rich mechanism" that keeps this from being a problem.

So that is the only change?

I have a stock 73 and I want to upgrade Alternator and still remain stock looking. I am planning on using 75 -77 280z Remanufactured Hitachi 60 amp regulator (Remy 14118) and get a 1977 solid state external regulator. Are there any modifications, like change support brackets or wiring?

So what size would fit ROTA RB? 60mm, 63mm or 73mm ? Do they clear the wheel center cap?

I am in the process of cobbling parts together to mount a AM/FM Hitachi KM-1520 in my 73. You need a bracket that mounts to radio on each side and then mounting brackets to install in car see attached pictures.
