I have a 2000 Cougar and after noticing a gas smell I tracked it down to what appears to be a leak on the motor side of the primer bulb. I removed the nylon clamp and it doesnt appear to be torn or cracked so I replaced it with a stainless steel clamp and snugged it down. I went back to the lake friday evening and notice the smell again and when I got to the boat storage I checked and sure enough it is leaking in the same spot. This time I snugged it down till I felt it get solid, I didnt want to over do it last time and crack the plastic fitting coming out of the bulb. Anyway, if this doesnt fix it I will buy a new bulb and a couple new clamps and see if that will do it. Naturally I am doing all of this by feel because of it being down in the bilge area. My question is, if i remove the primer bulb is the hose coming out of the gas tank going to have a tendency to want to syphon after i remove the bulb? I am just thinking ahead to hopefully make as little of a mess as possible.I hope snugging it down this time fixes the problem.

How old is the primer bulb and how old is the fuel line to the motor. If either are over 3-4 years old then they both need to be changed out. Ethanol in the gasoline will eat hoses that arent ethanol resistant. Can ultimately cause engine problem. As long as the hose is above the level in the fuel tank it wont siphon.

It does sound like your havin ethanol degradation. We suggest you replace the fuel job and main fuel lines (grey) with newer ethanol resistant lines. The fuel lines on the tanks will be A1 or A2 lines ans ethanol resistant.

Why do you even need a bulb on a fuel injected motor anyway,you never have to pump em up.

You need it for the longevity of your fuel pump. By the manual you should prime before every start, however the first of the day is the most important. You want to make sure the VST is full (prime) and turn the key on and wait 2-3 seconds before actually starting. Other important items are warm up to 120 (115 on racing motors as they have a lower t-stat threshold) and after a hard run let it idle for a minute or two before shutting down.

Sheff. I bought a sevice manual when I purchased my 2013. As right know I have only done a lot of reading. Once the warranty goes I will perform wat maintenance I can my self as I always have since my first cat in 89. A manual can save u hundreds of dollars. And only cost minumal. I guess I like to say I trust my own work more than I do others.plus some job are so simple to perform.2013 PANTERA 2MERCURY 200 PRO XSMINNKOTA 80LB FORTREX25 fury
