For a lot of years I kept a modified bolt in my tool box, with the first 1/4" of threads ground off, leaving a small diameter tip that didn't have to fight the sludge built up at the bottom of that hole. It made fuel pump changes a very quick job. Just barely snug the bolt against the pushrod and swap the pump out in a few minutes. Flat rate mechanics were an innovative bunch, as they got paid the standard labor for a job, regardless of the actual time it required. A good flat rate man could get 60 hours' worth of pay or more in a 40 hour week.
