OK, between screwing up my canopy frame and carb, I'm also trying to plumb my mechanical fuel pump. I've been trying to get to the bottom of this for a while and have made no headway.
I have an "early model" mechanical fuel pump on my O-320. Here is link: http://www.aeroaccessories.com/fuelpumps/lycoming.html
So I ordered the KB-090-T Tee fitting and KB-000 straight fitting from Van's per the "Carburated Fuel System" drawing. Neither fit.
Then, I thought the fuel pump had galled threads and I posted here. Somebody told me to use the AN833-6 90 degree steel fitting and AN924-6 jam nut which seems like a good idea but I won't be able to T it off for fuel pressure like on the Van's drawing.
Wanting to eliminate the fuel pump, I had another one sent. Still, no go.
I called Van's and they said theirs worked just fine in the fuel pumps in their shop.
Finally, I ordered the 07-00783 T fitting and 07-00780 straight fitting from Spruce. Still, no go.
So tonight I dug around some more online and I think I may be on to something. The early model pump like I have take a straight thread (this was told to me in an earlier post) and there appears to be an adapter out there. It appears that Sac Sky Ranch might have adapters...at $30 a pop!
Soooooooo, am I the only one out there with an early model fuel pump? How do I attach fuel lines to this pump???
Tomorrow I will call Aero Accessories, the people who rebuilt the pump. I hope they know.
Now, I have to get back to packing up all the stuff that doesn't work!
