Need reverse lookup, part# 996.573.045.01

Recommended Posts

This part is a small metal canister and attached metal lines. The canister is in-line between the left and right fuel rails on the smaller (return side I think) fuel line. The canister also connects to the AC compressor.

The canister is marked: 996.573.045.01, Kuhner 020.0348.01

I can't figure out what this is, and when I called Suncoast they could not locate the part.

I would guess that it is some kind of a cooling loop and the canister is a small heat exchanger, except that it seems like it should be on the pressure side rather than the return side.

Thanks in advance,

That's the one! Thanks Loren. I'll include model and year next time; it slipped my mind.

For entertainment's sake, it's a 1999 986, with a 2001 996 motor, last series of the 3.4L, e-gas.

Fuel cooler was my guess but I wonder why it is on the return line?

Interesting. The function is clear but the benefit seems minimal. I would think the HP advantage from injecting cooler fuel would be the big reason for such a cooler. Maybe the advantage of cool fuel in the tank becomes significant over an endurance race.

Thanks again,
