Question on changing SB mechanical fuel pump

I get by by using long nose vise-grips, and adjust them to about 3/16" open, then clamp the hose. Never had a problem with a leak or cutting the hose.

I just did the same thing a few weeks ago, on my 1966 that was last changed about 1978. The pump was OK, it was the carb that leaked after being parked. It was a good idea to change it just due to age.
