Marine PRO for varnish in a I/O boat? [SOLVED]

I have a 2004 I/O boat (Volvo Penta 5.0) that I recently acquired that has sat for many years. I just had a new engine put in. I also removed the old gas and added new. I started it up and it ran great for a short time before the fuel filter clogged. I’ve been reading that Sea Foam Marine Pro should clean up my varnish problem. Do you recommend this? Thanks for your time.
