i can only burn 30 gallons off a full tank then i run out of fuel.must have lost a pick up tube. has anyone ever taken the 90 deg fitting off the tank?? what kinda job am i in for???? any help would be great

I have not. But several tank websites show the schematics. Find out who the manufacturer is.

Just take the hose off and crank it out its easy .

Fountain made their own fuel tanks in-house (welded aluminum with reinforcing in the corners).
