yes...usually on one of the fenders...just follow horn wire back...these systems are nowhere as complex as the ones we use now.

I was just looking for another fuse and came across this diagram and it shows every fuse and relay and where it goes. The Fuel Pump Relay is in the O slot in the fuse box under the hood which is located near the battery. it is a 20 amp mini fuse. Hope this helps, i saved the link for future use if i need it, might be a good idea for you too. Good Luck here is the link.....
