I just bought a Yamaha Mini-10 Micron fuel/water separator (yes, I probably should have bought a Racor but this was a really good deal on Ebay along w/2 filters) and I have 2 questions: 1) Is there any reason I can’t use 90 degree elbow hose barbs? Would this in any way restrict fuel flow versus straight hose barbs? 90 degree elbows would suit my install better but I don’t want to create any problems by doing so. 2) dumb question but, does the primer bulb go before the filter (between the tank and filter) or after the filter (between the filter and the motor)? This is going on a 2-stroke 70 HP.
The bulb can go on either side of the FWS, but it’s easier to prime up if it’s between the tank and the FWS (you’d be pushing fuel through rather than pulling it).
I don’t know for sure, but I can’t imaging you’d have a problem using 90 degree barbs as long as your fuel line is of adequate size (5/16 should be plenty big).
between filter and motor is standard
between filter and tank makes it much easier to prime system, but if there was an obstruction, it would allow you to pressurize the filter assembly, and thats not good
