toomanyboats Posted February 5, 2012 Posted February 5, 2012 I just bought a new 25 hp 4-stroke Suzuki to replace my old 2-stroke Evinrude. Since the 4-stroke is heavier than the old 2-stroke (about 60 pounds) and since the boat is only a 15 footer, it seems like a good idea to get some of the weight moved forward. I would like to add 4 or 5 ' to the length of the portable fuel tank hose so I can move the tank forward. Is there anything wrong with adding that much length to the fuel line? Thanks Quote
Oyster Posted February 5, 2012 Posted February 5, 2012 No, thats not a problem at all. FWIW, the standard location for all fuel tanks in the smaller Simmons especially is under the bow decking too. Just make sure that you position the portable tank in a manner that your fill and vent combination is not blocked when full with gas and cause some overflow both in the summer heat when sitting or on a high plane if applicable.

Does it make much difference if I add the extra length between the tank and the primer bulb or between the primer bulb and the engine? A;am The primer bulb is not capable of pumping a long vertical head so the tank and engine should be near the same elevation. On a boat they can't be too far vertically. Other than that, the location of the bulb should not be an issue. Quote
hokeyhydro Posted February 6, 2012 Posted February 6, 2012 Tom is right. I run about 12' of hose from a 20 gallon tank situated as low as it can go on my V hull runabout. Just make sure you get a quality primer bulb - I use Yamaha but figure any OEM outboard one will work. Forget aftermarket off brands - they will pump for maybe a year and then quit. Quote
Tom Lathrop Posted February 6, 2012 Posted February 6, 2012 Yes, a good quality bulb is well worth the extra cost. Plastic ones are too stiff and not good for weak or old hands. All tend to be stiff when cold but rubber is better. The arrow on the bulb should be pointed vertically when pumping to allow the inlet and outlet valves to work properly. If the bulb is near the engine, you can hear when the fuel reaches the business end. Quote
