Thanks for the photos, JC; Mine is a 6oz soda bottle (attached to the blue bars on the side by DUCT TAPE). To get a good vacuum, I placed the tubing through the cap and INSIDE the bottle is a 1/2 long aluminum arrow (yes, archery arrow) and washer that is pinched when screwing the lid on similar to basic plumbing. Before I did that extra bit of engineering.....the tube would sometimes pop out.
So, JC, did/do you simply have your tube going into the lil' hole on top of the jar lid? If so, why would yours not pop out from time to time due to pressure or the occasional limb? Interesting that we are the only ones that I know of who did this and I take great pride in knowing that I was on the same level of GREAT thinking as an Engineer. HA!!!! I believe I even surprised you, JC, a few years ago when I mentioned that I had 'rigged' this up.
On a bit of info that I failed to mention when replying to Oakley earlier..... The 1700 radiator takes less coolant than one would think it needs. I've found that it will rarely go into the overflow (or in your case, on the ground) if it is just over the cells. When I put it as one would think (or feel better about on a hot day) it almost EVERY TIME overflowed. I don't have photos yet of my contraption but here's my radiator flow at work:

I have since fixed the gasket leak and have worked the living day-lights out of this lil' tractor since then. I regularly mow a 3acre yard with my finishing mower. use two 6' bushogs (one at the hunting place and one here at home on the orchard) and a box-blade that has cleared roots, made nice roads, put in culverts, graded my 350' drive-way twice a year and the heavy disks & breaking plows for garden and deer food plots. These lil' Japanese made Fords are nothing short of WORK HORSES!!!! I'd advise anyone get one.
By the way....I've since power washed the engine. I had not had the tractor a year when this video was made. Put new tires on it, replaced the 'alternator' and if I do any further work on it, it'll be paint it and re-introduce the lights.................BUT THE HORN DOES WORK! HA!!!!
