got a new fuel pickup coming for the LT166/ for $24 and a couple days wait right from Deere, not worth trying to make one out of brake line.... had to do that on my Ariens..... and being how rusty the original was, I am not sure I got the whole thing out... did sound like something rattling around within. if I duplicated what I got out might not have reached the bottom, and hard to tell how much longer I'd have had to make one.....
the guy I got this LT166 from, said it seemed the stock fuel pump was weak..... he jerry rigged a small electric pump onto it to try and get it to run.
I had it running on a makeshift gravity tank I held above the engine back when I had gotten it.
I have the tank out, poured out some pretty rancid gas.... about 1/2 of which, I added not long ago. I pulled the fuel pickup out, was clogged solid/ and rusty the whole length. I tried blowing it out with my air compressor and found 2 holes along the length of the fuel pickup tube, before it blew out what was clogging the end.... when I added gas a couple months ago and couldn't get any out by siphoning at the other end when disconnected at the engine I knew something was wrong back there....
I also filled the (plastic) tank with E85 gas last night and put it in a pan, drove to work with it in bed of my truck today, to slosh it all around.... seems to have done the trick in cleaning the insides of the tank walls....... I put a couple of other different things in it last night, that didn't seem to touch it though (one of the things I tried) was muiatic acid, I didnt want to leave that in there for long, as I dunno what muriatic might do to that exact kind of plastic.......
