I now have a new gas tank from S30 and would like to add a new quality sending unit.

Any assistance someone in our group can provide will be greatly appreciated. Cheers.

I'd also like to replace the four rubber pads between the body and the tank

Nissan still sells the sending unit, but WOW they have gone up in price. I picked up mine for around $225.00.

I was afraid I'd see a number like that. Maybe I should clean up my old original

It would be nice if they had those in stock. Matt over there said the aftermarket ones are hit or miss.

I purchased one for my 78 and it’s more intricate than a 240 and it works perfectly. I’m very surprised he would say it was hit or miss.

Before you buy a new sender, submerge your old one in CLR for 24-48 hours. You'll be amazed.

Thanks Mark, my plan is to remove the original sending unit from the tank inspect clean test and install in the new tank. Crazy to think, Nissan can justify such an astronomical price a simple OEM sending unit.

Welcome to the Zcar world. These are probably the last of the stock they had.

I also checked on Amamaya Japanese sight and they are 1,015.00. The word is out there.

Only ones we can get are the aftermarket ones which are hit or miss. If you want the best quality unit, you'll need to hunt around for an OEM one (be prepared to pay well over $1000). 

I have learned to anticipate repairing or correcting aftermarket parts before I install them. Some repairs are simple like chasing threads, other more complex like disassembling, cleaning, and reassembling. The fuel level function can be tested before installation, no need to soak it in gasoline.

I would guess that it might even be possible to swap parts from an aftermarket assembly over to an OEM sender to get it to function correctly. For the money involved, it might be worth the time. Buy a cheap aftermarket assembly for the parts.
