There are two types of fuel tank sender gauges: one with a "control unit" attached, and one without the control unit attached. My 92 cars both have the control unit attached, whereas the 91 has the -01 part number with no control unit. Would the -02 part number work on the 91 car??? The PET is not very clear.

Does anyone have the -02 part number sender attached to their early 964 that does not have a control unit attached?

Thanks!!!

Garrett,

FWIW, my 1991 C4 has the sender with the control unit (like your lower photo) - is that the -02 p/n?

This production date is shown on a sticker affixed to the hexagon nut of the sender.

So if you have the older one-piece sender it can be replaced as a part of a recall? What problem did the two-piece sender address?

Adrian

Need to know basis, I could tell you but then I would have to shoot you

The fuel indicator would fluctuate all the time. The control unit is really a damping device.

Adrian,
It's great to see you alive again on this board.......You've been gone for too long.......

MSchett2

So, now you shoot me?

Adrian

I am sort of taking a bit of a break from writing. This will not last. I just started doing a coffee table book on the Ford GT, just for fun.
I am waiting for my 911SC book to hit the stores. I am told the ship has been delayed a couple of weeks and 993 book is off to the printers to be proofed up before the final check.
Once I decide to start the 996 and M3 books then I will be gone again.
Ciao,
Adrian.

Adrian

Yep, pang pang (If you speak German you will know what this means)

Ciao,
Adrian.
