Re: 1957 Johnson 7.5 hp fuel connector problem
$1.13 each for the o-rings is spendy? They're not hard to replace and considering the first set lasted close to 60 years, $2.26 is a pretty good investment in your motor.
Using a modified drill bit (flattened ends on a grinder) I press the brass retainers out from the hose barb side using my bench vice. Once you have it apart, swap in the new ones, reassemble the pins and springs, press the retainers back in and you're done!
