In tank fuel filter

[xboxrox]

That sandy crap could just be crystallized fuel varnish, since apparently that stuff doesn't readily redissolve in fuel alone -- or else all it'd take to clean out varnish deposits in a tank is topping it off with fresh fuel, which ofc. doesn't work.

I've got plans to have the truck towed to the Kaneohe Marine Base (Five-O-Motors) and work on it there... Remove the gas tank since it has some major exterior rust on the front mount flange & shield anyway... Maybe try the vinegar & baking soda method of cleaning and (if I buy it) use a cheap explosive proof endoscope to ensure the tank interior status... Parts are coming from Amayama new OEM fuel pump in tank filter etc... If I can free up the needle seat on a spare Mikuni w/o having to disassemble it then I may install it too... A new in line fuel filter OFC and use a gallon of alcohol to blow out the fuel supply & return lines...

Must be more to it than this..? Today we installed a locking gas cap

Thanks sub for your attention...
