You can see one of two fuel tanks in back of the rear axle. This one is from a ’93 Yukon. In front of the rear axle is a ’93 Suburban fuel tank to give a 72-gallon range. Both tanks have factory pumps and senders that work perfectly with the gauge on the dash. The rear Dana 70 HD axle is packed with a Detroit Locker and 7.17 gears while a WFO disc brake setup helped the axle shed some unneeded pounds.
