Fuel Tank(s?sumtracler by Bass Tracker?) on Bass Boat

Question:

I recently bought a used Bass Tracker which has a 40HP Johnson motor with the original 6 gallon metal fuel tank and hose.sumtracler by Bass Tracker <SNIPShould I seek out an “official” OMC gas line and tank, or are they all about the same

Any type of gas line is fine, provided it is a fuel line. I’ve found the engine hard to start the first time after each filling. I presume that it’s loosing the pressure inside the tank. I fill then close the tank.sumtracler by Bass Tracker  The seal on the gas cap is 8 years old, but looks okay. I then squeeze the pressure bulb several times, but it never seems to become “hard” to squeeze … so I’m not sure if I’m developing enough pressure inside the tank. The engine always starts,sumtracler by Bass Tracker but it takes considerably more time to start after re-fueling. Am I doing something wrong here??

Single line Evinrude or Johnson outboards pump the fuel by suction into the carburators.  The tank must be vented for proper operation.   The fuel line bulb just pumps sufficient fuel into the pump to allow it to pump.sumtracler by Bass Tracker  If air cannot enter the tank, the bulb cannot move fuel.  Make sure the tank vent is open.

I recently bought a used Bass Tracker which has a 40HP Johnson motor with the original 6 gallon metal fuel tank and hose. Although I’ve only used it a half-dozen times, it appears that I burn 2-3 gallons of fuel per fishing outing – just enought that I can’t feel comfortable starting on the next trip unless I stop and fill up on my way to the  boat ramp. It appears that I have room in the compartment where the gas tank is stored to put a second 6-gallon tank, but have the following questions: Would it make more sense to replace the original tank with a single 12-20 gallon tank?   – fewer fillups, but no redundancy of tank and fuel line   – two six-gallon tanks with two gas lines would provide full redundancy Any preferences for plastic or metal tanks?   – Boater World had plastic tanks on display, but they all specified ” for external storage” or something similar… Should I seek out an “official” OMC gas line and tank, or are they all about the same I’ve found the engine hard to start the first time after each filling.

Kit Maloney Kit, It maybe that the fuel line you have is simply wornout and while not

yet leaking does not provide an airtight seal.sumtracler by Bass Tracker  I had an old skeeter with twin 6 gallon metal tanks and one fuel line that I could conect to either tank with a quick disconnect.   There are a couple of different styles of connections based on how old the tanks are.  I would think you could find a similar tank and just switch the fuel line at the tank when needed.  No need for an additional fuel line, just another tank.  If the fuel line you have has grown stiff and brittle, replace it and you might find the motor easier to start. Hope this helps. B. Weaver – Hide quoted text — Show quoted text -

Back in May I bought my first bass boat – 17ft. Grumman w/74″ beam and 50HP Johnson – all brand new. It came with a six gallon tank and I bought another just in case. I bought one from Wal-mart which is the generic brand found everywhere. I don’t like it as much as the origianl OMC tank, but the differences are not serious. The OMC has some type of valve that automatically vents the tank, whereas the cheaper one has a screw down vent on top of the filler cap. The hoses don’t appear to be as high of quality, either. But, it was cheap enough. :) I like having two separate six gallon tanks. It is takes the worry out of gas levels, as I usually always keep a full tank. The only times I run the other is when I am trolling, which is seldom, sight-seeing, or boat-camping. Usually six gallons lasts all weekend. Separate tanks would allow you to let someone take the tank and buy gas for you while you’re out fishing, too. The second tank should include the bulb, line and quick-disconnect. It takes only a minute to switch tanks. I’ve found the engine hard to start the first time after each filling. I presume that it’s loosing the pressure inside the tank. I fill then close the tank. The seal on the gas cap is 8 years old, but looks okay. I then squeeze the pressure bulb several times, but it never seems to become “hard” to squeeze … so I’m not sure if I’m developing enough pressure inside the tank. The engine always starts, but it takes considerably more time to start after re-fueling. Am I doing something wrong here??

You say the boat is used. Has it had a tune-up? You could even have the heads re-torqued. I had this stuff done at my 20 hour check. When I start my boat I have to push the key in to prime the carbs. It will start if I don’t, but it would take a while and isn’t good for the motor. Good luck!

Any preferences for plastic or metal tanks?

Go with plastic. OMC doesn’t even manufacture the steel tanks anymore. Should I seek out an “official” OMC gas line and tank, or are they all about the same

They are not the same. OMC tanks meet a higher spec and when comparing the two side by side, the differences become quite clear. Ditto for the fuel lines. I’ve found the engine hard to start the first time after each filling. I presume that it’s loosing the pressure inside the tank. I fill then close the tank. The seal on the gas cap is 8 years old, but looks okay. I then squeeze the pressure bulb several times, but it never seems to become “hard” to squeeze … so I’m not sure if I’m developing enough pressure inside the tank.

First, the fuel system is not pressure driven (only the double line tanks from yesteryear were). It is not necessary for the brimer bulb to get rock hard as it’s only job is to fill the carbs with fuel. Once the engine starts, the bulb will go soft as the valves open within it. As for hard starts after fuel, I can’t think of any reason this would occur other than the possibility that you tilited the engine during the process. Otherwise, the engine doesn’t know what you just did. :-) Regards,         Dave Brown         Brown’s Marina
