Comments on my fuel tank, and stuff...

Today I did something that I've wanted to for a while: take off my tank and see if there are any rust issues. The bike was sitting for 2.5 to 3 years in my garage so I was concerned. I removed the tank, drained the lest vestiges of old fuel, then removed the fuel tab and checked the screens which looked almost new. After replacing the tab I swished around a few pints of new gas, three times, and pouring each swish into a large jar, filtered by some coffee filters. There were zero particulates there so I felt good about that, too. My questions relate to both the fuel level sensor underneath and the fuel tab. As for the sensor, it's a roughly squarish thing centered underneath but there is a long "tail" coming off it that looks like a hose should be attached. What is that for? As for the fuel tab, I noticed in the manual, which I happily downloaded, that it refers to a PRI (prime) setting on it. Mine doesn't have that. Mine has an OFF position, an ON position, and a RES (Reserve) position. Is this unusual? Of these three positions there wasn't a way to drain the fuel out through the tab.

The early models had a prime position on the petcock, not sure when it changed. I've drained my tank by placing it on a bucket and applying enough vacuum on the port to start the fuel flowing and leaving it until the fuel drained out. As long as the valve is open you can switch to reserve and almost completely drain the tank.

will take the petcock first... there where 2 different ones used on the vn750. earlier years had the prime position, new years had the one with on/off/res.

the hose on the cover for the sending unit. normally nothing on that, but if you do an ear shave, that's a good place to put the carb bowl vent hose

edit: I type too slow
