So much good information here. I am not looking for more hp or any fancy tune. I am simply trying to provide cleaner fuel to the motor. Recognizing that the factory set up is sufficient for a factory tune, my fear is that by inserting another filter (of which I have plenty lying around....free...marine debris, stuffed in nooks and crannies on my boat) I will possibly strain the injection pump unduly. My plan is to plumb in a filter close to the tank, install a 10 micron element - and suck the fuel through it with a small 12v pump. It will probably feed pressure to the injection pump at about 8PSI give or take. This type pump will probably move maybe 25 gallons per hour. I may plumb a bypass to it so that should it quit on me I can bypass it and the filter.
Guys these lil pumps are about $20 and I have never had a problem out of one other than old age. I like them for priming the filters after a filter swap because all you do is spin on a filter, leave it a tad loose, run the pump and when the filter is full and begins to leak, snug it up. Viola....no fuss no either, no cracking injectors etc...
