COA question - "S" Options

[Sean F]

Just got my COA and one of the optional features listed is "911S Instruments and Oil Tank"

Car is a 1971T

How are these different from stock?

Thanks

A T came stock with an oil tank with no oil level sending system. It had a tank that had an indent where the oil sender would normally go, but there was no large hole or tapped small holes to insert and attach the sender. It also had no oil level gauge. The side of the gauge that would hold the oil level part of the gauge on an S had a big area that lights up when you put on the emergency brake on a T. So if you got the S option for the oil tank with sender then you also needed the S gauge. The tanks are identical but the T tank has no way to attach the sender. You could convert a T tank to an S tank but you would need to remove the tank (easy) cut the hole for the sender ( apprix 1 3/8 inch) and then weld a ring around it so you can drill the 5 or 6 holes, and tap them so you can attach the sender ( not easy ). Then buy the proper gauge. I believe the wire for the sender is in all the cars.

Excellent, thank you.

My 70T with S trim came with the oil level sender in the tank and the S gauge.

Likewise, but I'm pretty sure these gauges were standard on Sportomatic equipped cars regardless of whether or not they were ordered with the Appearance Group.

My T was a european delivery car so it had no options let alone "S" options.
Good info since I want to add functional S gauges at some point.

Please post some pictures if you upgrade.
Cheers.

Additional info, I don't remember the exact dates of the different oil tanks, but basically you can do the following.
All the tanks except 1972 have the same attachment points.So you can use a tank that is apprepriate to the year of your car, or any other tank, except 1972, that includes the stainless steel 911 tanks. To use a newer tank than the one for your car you only need to open the hole in the inner quarter panel where the filler and filter stick through.The SWB cars had a hole for the filter console, and one for the filler, later cars eventually had one large oval hole because the filler was welded to the tank and you needed more room to actually get the tank into position. Naturally if you want to keep your car stock looking you need to get the proper year tank, with a sending unit. That stainless tank is really nice however?

Additional to the above "The oil level gauge is useless" you should never rely on it.

If you have a "Sporto" the tank will also have an additional two outlets for the torque converter.
