M880 gas tank question

[dispatcher1011]

Does a fuel tank in a 1977 M880 have a drain provision? Or must the tank be dropped to remove 15 gallons of rancid fuel? BTW- it's a plastic tank... don't know if they all are...

The tanks we have do not have drains. WE removed the tanks and cleaned them out. To my knowledge they are all plastic.
There is a screen on the end of the fuel pick up that can be varnished by old fuel to the point it is not going to work right. With the tank out, you can check out this screen to be sure it is going to flow the fuel.

All the ones I have seen are plastic.

there is no drain on the tank.

If you suspect the screen is cloged, simply pull the fuel line at the pump and blow out with air, this will remove the screen at the end of the pick up tube, then install a new inline filter between pump and carb.

Pulling the tank is easy, expecially if you disconnect the drive shaft at the tranny, I have found that usually the hardest part is getting the hose off of the fill tube...

Yup, they're all plastic with no drain. I took the box off to blast the frame and rear axle so it was easy to clean the tank and get it ready to reinstall.

I just did the same thing on mine. Lots of nasty crap in the tank!
