Primer bulb location

My fuel filter/water separator on my C22 is located in the bilge between the fuel tanks (along with lots of other stuff that shouldn't be there). I plan to move it to the void above the starboard fuel tank. That seems like a protected place with easy enough access. My question is where should the primer bulb go? If I move it up into the splash well it will sit horizontal, which I understand is not optimal. I could place it next to the filter and leave off the fiberglass panel between the tanks and cockpit -- any issue with that?

I remember the instructions saying that the bulb exit should face up. Mine is in the splash well, but there is enough slack such that I can squeeze it at a 45 degree angle. Probably only matters for a quicker prime on the bulb. My bigger concern was what the sun might do to it. My black rubber cable boot didn't last two years before getting cracks in it. Bulb has done better but it still might last longer if tucked away from the weather. Might have to squeeze it a few more times.

My two, (twin 40 Yamis) are in the splashwell, have been and have worked well, just a bit stiff, but then so am I come early morning, so we get along well. Have never paid much attention to the up or down end. Would have to go look but the boat is up in Bellingham this week.

Thanks all, mine are going in the splash well. And I won't worry about the bulb sitting level. Several years ago I was having a fuel problem on my jet boat. One mechanic tried to blame my horizontal primer bulb (check valve not seating properly). The real problem was a sticky piston in the low pressure fuel pump on my new engine.
