Well I finally got the parts I ordered from TAF back in December. One of the parts was the 2 plumbing parts that make up the fuel pump assembly. I was originally going to purchase the ones used on the 912 from Rotax, but it seems you can only by the whole fuel pump assembly which is quite costly. I want dto use the Rotax fuel pump box to help protect the pumps a little more then what TAF does with them. The trick is getting all the parts to fit in the box. It’s a very tight fit, but I think it will work. Unfortunately I ordered the wrong check values. I got these from Aircraft Spruce and they’re the 3/8″ hose barb, but I needed 5/16″ hose barb which I have to get directly from Andair (in England). I hope it doesn’t;t take too long for the parts to get here.
The check valves need to squeeze in on the sides. The bottom manifold is a bit wide so that’s the main issue with the space. I wish they made it about 1/4″ narrower, but I guess they weren’t thinking it all had to fit in this box. At least height wise it fits. I was almost going to not even try to put it together since upon first look it really didn’t seem like it was all going to fit. I don’t know if there’s a better way to do the in and out of the pump assembly. I’d rather just have an AN fitting there and not the hoses, but I think that’s the best I can do unless I want to have someone solder on a fitting.
