The best fix for the hose problem is a steel tube bent to the shape you need
with rubber couplers at both ends. The rubber couplers come as a "step down"
or straight. Make a pattern using wire, and check your progress often. The
like all skills is a acquired skill but the end items are great and fan
proof.
IMPORTANT NOTE!!!!! THE SAND MUST BE DRY!!!! ANY MOISTURE WILL CONVERT INTO
STEAM CAUSING THE PLUG TO BLOW OFF!!!! THIS IS VERY DANGEROUS AND AS WITH
ANY USE OF A TORCH BE CAREFUL
To bend the tube without collapsing the sides you'll need to "sand mandrel
bend" it. here's how:
Determine over all length, add 6" to each end.
Weld one end shut (with a plate) fill the tube to within 2" of open end with
clean dry sand.
Tamp the sand down (pack it).
Make a tapered wood plug.
Jam the plug into the open end of the tube (really hammer it in).
Using you oxy/acet torch heat the area to be bent to red hot and slowly pull
the tube to the desired shape.
Work slowly one bend at a time, allow the tube to air cool.
This method will produce clean flowing bends of constant diameter, the tube
will not collapse if done correctly. You may also weld on a steel step down
as part of the steel tube and use same size rubbers (each end) on the ends.

I have the solution for the varied hose diameters. I have this special
hose set-up on my blower motor that this company sells ....... anyway when
they connect from their hose to a smaller radiator fitting they supply you
with a piece of hose to slide over the fitting to increase it's diameter to
the size of the hose. It's just rubber hose that's used as a spacer. I
pretty sure that will solve your problem!
Another trick I used to find my radiator hoses is to take a piece of flex
tubing "Metal defroster ducting tubing 2 1/2" or so" and bend it to the
shape I need and take that hose with me to the parts store and ask the
person at the counter if I can go and pull hoses myself to find the one that
will work.
I've also take the two different hose and mated the two together with a
piece of pipe and four hose clamps to bend around obstructions.
