How hard should fuel bulb be?<br /><br />I'm new to boating and have just purchased a 15' half cabin with a 1990 Evinrude 60HP. Being a nervous new boater and not wanting to get stuck with no gas in the middle of no-where, I purchased a spare fuel tank (same make and model as the one which came with the boat).<br /><br />I attempted to plug the existing fuel line into the new tank but it would not fit. At 1st I thought the fuel pick-up on the new tank was incorrect as it was different to the one on the old tank. I went back to the boatshop and have discovered that the fuel pickup on the old tank was for a mercury and the fuel line connector was also a mercury (the connector at the engine end was evinrude). To enable me to use both tanks they advised me to replace the fuel pickup on the original tank and the connector on the fuelline to evinrude types (as they should be anyway). I have since done this.<br /><br />Prior to making this change (eg using the Merc pickup and fuelline connector) the bulb could be pumped to a point of what I would call hard, however with these new fittings it does pump up but not as hard (I can still compress the bulb by approx 1/4 -1/2" after pumping).<br /><br />I have run the motor (out of the water on muffs) with the new fittings and it starts OK and I let it run for approx 5 minutes and it appeared to be fine.<br /><br />The Merc fittings were very snug, however the new evinrude fitting are slightly lose and have some movement (between the fuelline and the fuel pickup), the boating store says this is normal, however I'm concerned that air might be getting in.<br /><br />Is this movement in the bulb normal? is there any test I can do to check if air is getting in (prior to taking it on the water).<br /><br />Any advice would be greatly appreciated.
