Hello,
The rebuilt fuel pump from Bud's seems reasonable and the best choice. Your old pump is easily fixable most likely it is just stuck. If your service man just wants to do a swap get the rebuilt pump for now. Keep your original and have it repaired. Sell it to recover some of your expenses or keep it for a spare.
If your car has AC some hose replacement can be much more complex. If it does not then certainly no hood removal is needed and most hose replacement is fairly straight forward.
Long periods of inactivity are hard on any complex machinery. Try to get the car out for a drive at least every few months. Just starting it in the garage and not driving it, is not good enough exercise. Remember, garages kill !
Try adding a little gas stabilizer and / or two cycle motor oil to the gas before winter storage. Run the engine for a few minuits before storage. This can keep fuel system mechanicals from getting stuck during storage. However nothing is better than a nice 15 minute drive to keep brakes, exhaust, transmission, differentiial, tires, fuel system, etc, in proper working condition.
Brake fluid and anti-freeze must be changed on a two or three year interval or other expensive problems will develope.
