This was a direct replacement. I did have to purchase longer mounting bolts, but that was it. This is a piece of mind product. I highly recommend it.

A great upgrade to any aircraft, especially those with a “bail” which secured the bowl.

Steve’s aircraft makes the nicest gascolator. This is a must replacement for the old glass bowl unit.

Great product however order AN913-1D’s to plug extra holes otherwise you may be waiting for additional parts while installing. Aztec needs one plug each side, no sure about other aircraft.

We installed this on our Cherokee 180. I wish we had done it a long time ago. No more fusing with the OEM part! The Steves unit is finely machined and a joy to look at. Expect to have to fuss with the Piper mounting bracket to get it flat and to do some minor cowling work to accommodate the drain valve. Be sure to order the 90 degree fitting for the drain.

This is an excellent design and solution for my leaky gascolator on my Piper Cherokee. I would suggest Aircraft Spruce add the 90 Deg fitting (AN914-1D) to the recommended parts as it is listed in the Steves Aircraft Cherokee Hints. It could have saved me from having to make an additional purchase where my shipping was more than the part cost so I could get my plane back up flying. As far as I can tell the Cherokee Hints paper is only shipped in the box with the STC and instalation instructions.

Ordered SA3-00B as called for on a 1957 172. First one arrived was obviously a used return. Pipe putty residue all over unit and in threads. Immediately called into ACS and asked for overnight shipping since my plane was down for annual. Rep agreed. Replacement arrived next day, this one brand new. Installed without issue and was pleasantly surprised to see zero modifications needed done to the airframe for install. Unit bolted up to OEM bracket and all lines installed perfectly. New system is simple, elegant and seemingly reliable. Replaced tall glass-bowl unit with terrifically awkward latching mechanism.

Very happy with product. Easily replaced my previous gascolator and is manufactured with high quality. STC paperwork was included as well as installation instruction. Highly recommend this product.

The 1/4npt taps could have been 2 or 3 turns deeper, but still a nice part.
