Dum question, on prime what level is the fuel taken from?, same as run or reserve? and is reserve still vacuum operated same as run?

 

PRI feeds from RES I do believe, or from both of the others. Reserve is vacuum operated, as is "ON." And reserve is only a function of the standpipes/filter; if that's missing it's all reserve, all the time.

 

I used PRI the other day as the j had been sitting awhile but when i got to work the tap was leaking so it was time to empty the tank and pull it of. Got some new O rings from the local dealer to fix the leak and made up a stand pipe from copper tube. The PO had taken the filter/pipe assy out explaining why i had no reserve. Another problem solved.

 

A lot of people never learn this.

Fuel comes out of the tank via a point above the bottom of the tank, often by a raised tube.
It only comes from the bottom of the tank on reserve.
If the short raised tube leading to the fuel tap is missing, on = on, with no reserve option. It bad when you learn this 800 meters from fuel, and its too hot to push.

 

What would the usual reserve be on a 750 Seca, and how difficult is it to change? If I'm remembering capacities and fill levels right, I've got at least a gallon and a half when I go on reserve.
