The hose that came with mine has a crack/opening in it. Can the hose be replaced ?

Yes replacement parts are available from distributors.

Can this be used for fuel transfer

Not made for petroleum products. The fuel would degrade/eat up the rubber stopper inside.

What is the diameter and length of the suction nozzle extension?

I lost track of that part from the get-go. It was maybe 8-10 inches long, approx. half inch wide. I use the pump w/o a tube at the end, UNLESS I need some depth or reach, and then I use a piece of "swing pipe" which must have a little of outer surface shaved off in order to fit; and I can cut the length as I need. Not a bad product, and I couldn't find this style in Wichita, where I live, so I ordered this, not bad priced.
