I have a 91 prostar and I don't have the inline spin on separator in between the tank and the fuel pump. Don't know why, but the previous owner must have taken it out.

Is it necessary that I have one on there?

It has run fine without it, but now I'm wondering.

Thanks!

It may be that it never had one. The manual for the 1990 PS 190 makes no reference to the spin on filter. My 93 had a fuel/water separator on it, but it was a pretty short lived piece of equipment. You should still have a housing near the fuel pump that has a fuel filter element in it. If they got along without that part for the years preceding your boat, I'd think you would be fine without it.

Very easy to add one - I have done it my my 2 190 PS (89 & 92). A Racor was usually mounted on the engine - no longer can get filters for those. Just mount the bracket somewhere in the engine compartment along fuel hoes line coming from the back fuel tank - cut the fuel line and hook up. Make sure to fill the filter with gas before you spin it on or you will have a tough time getting the engine to start (air in the system). If there is still a filter element in the Racor I would remove. Spin on filters/separators are cheap and you can change a couple times a season.

Along the same lines I have also installed a strainer on the fresh water intake - it saves a lot of wear and tear on the impeller - it is amazing the volume of water that you suck out of the lake and these strainers keeps little sticks, pine straw etc from reaching the impeller - make sure it is sized to handle the volume.
