Engine back fire

I have a 2.7 from1977. The engine is working properly, but randomly it backfires a puff sound intermittently not continually but about 3 times per minute or something like that. I think it is not normal. What it could be?

I had a 77 911 S Coupe. Most common cause of that type of backfire sequence : Your fuel pump is on the way out.
