The International Cessna^® 170 Association

Does anyone know the P/N for the fuel drains in the wing, my IPC just shows them as a plug.

v/r,

Jud-
I just had mine replaced yesterday. They are the push-to-drain type without the 1/4 turn lock and don't require sticking a pin up into it. They are also short enough the door won't hit them.

They are made by;
Safe Air Products
Garden City, Michigan
734-522-8360

p/n CAV-170

Glacier Air Parts at the Palmer Alaska Airport stocks them.
800-478-7100 or 907-745-7100

Aircraft Spruce also carries them at $11.95, if you don't want to have them sent from Alaska:

I keep a couple of spares in the glove box.

As Richard pointed out you can get the new drains from the source he listed. That is where I got the last ones I purchased. Keep in mind that if yours are dripping, it may be some trash in the drain or one or both of the o-rings may need replacing and not the drain itself. o-rings are easily obtained and are cheap and its an easy fix (no fuel draining required). Remove the drain and have a plug to screw into the fitting so you can look the drain over or if you choose you can put your thumb over the opening while you or a helper examines the drain and/or replaces one or both o-rings. (I would recommend having the helper use his thumb so the fuel goes down his arm, not yours ) I had one leaking recently and when I drained my tanks to replace o-rings in my fuel valve, I saw a large piece of trash that looked like a piece of red paint flake stuck in the drain valve. Removed the trash, looked at the o-rings & found them to be OK and put the drain back in. No leaks when I filled the tanks again. However, I recommend replacing the o-rings if you remove the drain since you have it in hand anyway. I happened not to have the replacement o-rings there at the time, but will get some and do so.

A little bit off the subject, years ago and I don't even recall the person or the fly in, he had a badly leaking quick drain. No one had a spare drain or a O-ring. We pulled the drain out (while someone held their thumb over the hole). The O-ring was completely gone. I happened to have some silk thread in my tool bag. I wrapped the thread around the o-ring groove enough so it would seal and stuck it back in. It held until he got home. I now keep a spare drain in my bag also.

Thanks for the reply fellas, the reason i ask is I've come upon two cessna drains p/n s2020-2 that's i've been trying to referrence to see if they'll fit. I went to Iwantcessnaparts.com and used the search to find what the plug was superceeded by and what these p/nS2020-2 brought up. They don't mention fitting the 170 but they do mention fitting the 152, 172,182, etc. in both cases. I planned on draining the fule for the annual anyway to lube the fuel selector, maybe I'll just find out the old fashion way.
