Quick Connector (Fuel) Question

[mpritch272]

I'm thinking of connecting things as noted in this sketch- Does the use of quick connectors impact anything? I have a replacement squeeze bulb in my tool box in case I need to ever swap while on the water, and it comes with quick connectors on both ends, I'm thinking of adding one more on the motor side of the existing bulb so I can swap out just by releasing the connectors.

I added the existing one so I could decarb, and I haven't yet installed the RACOR water separator, but have already added the matching quick connector to the output of it. I currently have a quick connector on top of the onboard tank (removed the antisiphon), but am planning on doing as t he sketch shows. Looking for suggestions, thoughts, etc.

Are the connectors leak proof, and do they restrict fuel flow in any manner?

What is the general guidance on the use of the quick connectors? Thanks-

as long as the orings are good i see no problem,. use oem connectors, some of the aftermarket say johnson/evinrude/suzuki, they leak the size is just a little different, than the oem connectors.

I had OMC quick connectors on my separator before installing a fuel tank selector valve in my boat. What I found is that it is easy to get the fuel line partially on the connector that is mounted on the separator, resulting in a fuel spill in the boat. Obviously this is not good from a safety standpoint but it isn't just fire that becomes a hazard - just a little bit of premix on the deck can become very slippery, especially if there is a little water combined with it.

I recommend that you install a fuel tank selector valve and use hose barbs at all points except at the motor and the 6 gallon aux tank. You can then run an aux line from one of the barbs on the tank selector, and have that line terminate with a quick connect for the tank. If you do not have the aux tank in place all of the time, be sure to cover the quick connect on the aux line with something. This will prevent getting dirt/debris in the connector.

What size motor are you talking about?

I believe Johnson-Evinrude had a 90hp limit for the quick disconnect fuel connectors. Years back they had them on the 115's, though. Do not run them on higher hp motors due to the restriction. You can see why when looking at the size of the holes for fuel flow in the male connector.

Re: Quick Connector (Fuel) Question

why not just use a aftermarket hose for the portable tank. a lot easier, and safer, and cheaper that all those fittings.

I think TD makes a good point. This is especially true if you have a kicker on the boat too, because it gives you a completely separate fuel supply.

I installed all the plumbing on my boat because I needed a fuel selector anyway, and the mounting positions for my aux tanks are in a separate, self draining deck area at the bow of my boat. This keeps the tanks (2) out of the main cockpit area and allows me to balance the boat when using the full 24 gallon aux tank capacity. My main purpose for being able to carry a total of 48 gallons (2 main tanks, 2 aux tanks) on the boat is to extend my range for search and rescue operations. As such, having an uncluttered main cockpit, and the ability to switch tanks quickly, is important.

One thing to remember about aux tanks, however, is that modern gasoline is not stable for periods as long as was the case years ago. I think I read somewhere here on IBoats that this is because of the ethanol that gasoline now contains. Because of this, it is a good idea to transfer the fuel into a main tank and refill the aux tank periodically.

very true.
