3/8 ball valve for main fuel valve source?

[Jim Herpst]

Just discovered my fuel valve iI purchased from Tim a few moons ago however never used is 1/4. Not his fault . Mine... as I am restoring to use an 0200 now.

Ideas on a 3/8 fuel valve source? I saw some posts from back in 2006 that said that Home Depot had the same valve that Wag Aero has or had.

Also put on the on the new tank today as purchased from Wag Aero.. was thrilled how easily it fit with out having to modify(meaning hit with a rubber mallet as the indentation they did fit fine!)
NOW however I discovered the bung at the bottom of the tank...firewall end is 1 and 1/4 inches further back away from the fire wall than the original. So I was thinking the old valve screwed in directly to the tank.. riiight? Wonder if I can simply use an elbow from the mislocated bung and move it to fit "in line" 1 1/4 inch further away and use the same cut off rod that goes to the panel.. of course can always shorten it as well...

It is legal for the O200, the main thing is the 5/16” ID hole for fuel flow. And the 3/8” to 1/4” elbow flows enough too. the 3/8” valve flows the same as my 1/4” one

Well if you say it is then so be it. I am good to go with your valve .... Now question, rather than screwing it directly to the bung is it ok to mount it to an elbow coming out of the tank and put it in line which will be closer to the firewall ...where the old one was . Reason I am asking is it does take a bit of muscle to move it on and off. Do not want too much moment to flex the tank/bung hole

It will loosen up with some fuel, use the original elbow with the finger sceen.

And damed it all I no longer have the original elbow nor the finger screen . Any ideas ? Darned smallest things.....

There's a Taylorcraft SB issued 1962 by Giberti Aviation for STC SA1-210 and then reissued by CAP in 2010 as SB01-STC SA1-210 for C-85's. It's to ensure 5/16" ID all the way to the carb, including all fuel valves, lines, and fuel strainer.

Yup. Thanks

Spruce has a couple of finger screens. Cessna used parts check e-Bay or do a search by Cessna P/N-specs?

When I wrote that suggestion I had looked a e-bay and saw several Cessna fingers with various threaded fittings for sale. So w/o thread specs and ID it's hard to know what they are. But, given some options and initiative maybe there's a fix in there somewhere. My tank valve arm sits on the right side of the valve looking forward. Pull-off - push-on. Probably a ball valve unit, I don't know what kind or model. I siphoned the tank clean a year ago and there's a finger screen down there. Then 3/8" tubing through Steve's gascolator on to flex hose under firesleeve to the MS carb. The wing valves are under my panel. They look similar to the main tank and are likely ball valves new in origin. Owner built parts probably but my IA said good to go.

Gary and all that were helping here I looked in the proverbial box where the old valve really should not be and lo and behold there it was with the elbow with the finger screen attached , In spite of my concern of the WAG Aero placed Bung being in a different location it appears it indeed is a perfect fit to the new valve (Which size wise is no different from the old one) meaning the fuel cutoff rod works in the spot it is in without modification.. Phew !

Good find Jim. One issue with Taylorcraft is the almost complete lack of support in the form of factory prints. Three TCDS holders and folks like Forrest (perhaps?) sitting on data. Go to Piper and Champ groups and most of what constitutes their airplane is available in some form. I can see where this happened to some degree. The factory didn't have a production certificate, so...

"Production Basis: None. Prior to original certification, an FAA representative must perform a detailed inspection for workmanship, materials and conformity with the approved technical data, and a check of the flight characteristics." So whatever parts and work was accomplished 82 years ago (in my case) was inspector-dependent upon completion. Different inspectors...different airplanes...built to suit and fit by Taylorcraft. And that's where we are today....an uncertain heritage and build history using whatever parts were available. Opinion only.

[Jim Herpst]

Agreed!

What and who is this TCDS holder:

Type Certificate No. 699 (CAR 4a) Franklin engine. Taylorcraft, Inc. Connellsville Airport Connellsville, Pennsylvania 15425
Type Certificate No. 700 (CAR 4a) Lycoming engine. Taylorcraft, Inc. Connellsville Airport Connellsville, Pennsylvania 15425

If I ask on Facebook I'd probably find out, but don't have the energy today to deal with that complex reply format. Do they have prints or just a TCDS document?
