Fuel valve bracket

"after learning the technique..." I know what you mean. I even wrote instructions on mine.

I decided not to split my floorboard after all. After trimming some corners that were catching and learning the technique, the floorboard isn't that hard to remove as one piece.

Here is an update to my fuel valve mount. I made a new piece out of .025 material to replace the .125 thick piece from the kit. The old piece was 12oz and the new piece is 2.2oz. There is a 1/2" lip bent down at the front and the back to stiffen it as well as the two flared holes. I still need to add the screws and spacers to mount the gascolator.

I didn’t like these fittings after all…they are very thin and cheap feeling compared to AN fittings, and also would be too long when installed and interfered with the fuselage tubing. I’m going with the fittings Arborite has and thanks for posting the info!

I really like that spacer you made. very nice work.

I think I understand already. My assembly will also come out without removing anything but the four bolts assuming I have access to disconnect the fuel lines. What I won't be able to do with mine is slide the fuel valve out of the bracket by just removing the selector flange screws and gascolator screws. My choice to use a mounting spacer under the selector flange in place of a slotted part precludes that option and forces me to remove the selector flange from the selector before I can separate the selector from my mounting bracket.

My assembly will come out without removing anything but the four bolts. once the assembly is off the plane, i remove the flange screws from the selector and the two bolts holding the gascolator. then those two parts slide off the bracket assy. my slot is facing forward so it all comes out the front. sorry for all the verbal description. a sketch would be better but i’m lazy today…

I think the access options for your installation and what I'm planning are very similar. The main difference is that I haven't figured out yet what my cutouts will look like so I don't know what kind of access to the fuel lines I would have before removing the mounting bracket. Like me, you would also have the option of removing the mounting bracket first and then having full access to the valve and gascolator. To do that, you would have to remove the mounting flange on the fuel valve the same as I would have to do.

interesting. in my case, i have everything mounted to the big triangle. four bolts and the whole assembly comes out - brackets, fuel selector, gascolator. then i can disassemble on the bench as needed. that’s why i need to access the three line nuts first. i think i can reach them all from the sides or through the cutouts. if not, i’ll make an access panel on the belly.

[David Swartzendruber]

In my installation, all the parts over the valve and gascolator will be easily removable and that will leave the valve and gascolator completely exposed. At that point, accessing the fuel line connections should be no problem. Any cutouts I have will be simply for saving weight.

I have enough clearance and enough removable screws to slip out the big triangle for access, also have a small bottom panel and the whole bottom if necessary.

That looks likea better way to go than my two fitting approach. I didn’t see those before when I was searching.

Everyone has great ideas on how to service the valve and gascolator, but i think the tricky part might be accessing the nuts where the fuel lines connect. Are you making access from the bottom with a panel or are you planning on reaching under the triangular piece? I made pretty big cutouts to hopefully help in the process (and save a few ounces).

I had the same issue with AN5 lines and fittings down to the valve. I found these adaptor fittings for the Newton valve (that’s what these are) at ACSpruce. The part that screws into the valve is not normal tapered pipe. It has an O ring seal. I used the 05-04454 adaptor to allow a regular AN5 fitting to be used. IMG_0500.png

I like the handle on your valve better than mine. Yours says FUEL instead of the SPRL advertising that mine has.
2-12-2024 Update: I contacted SPRL directly via email (info@newtonsprl.co.uk) and asked about purchasing the other style selector handle/lever. They are sending one to me for $20 postage included.
