Question on changing SB mechanical fuel pump

OK- sounds like I'll want to drive enough to use 3/4 of a tank-full before I start this job. That hose between the fuel line and pump inlet is the last piece of old fuel hose on the car- original, I expect. It will be replaced as part of this job. I'll use the same high-quality Gates-brand fuel hose I used when replacing the fuel gauge sender last year.

Side note: the original fuel hoses on this car were/are in remarkably good condition. They are flexible, not gummy, hard or collapsing, even though the car has been driven on ethanol-blend fuels for 20+ years.
