Do I Have the Correct Fuel Connector?

[minuteman62-64]

..... or will this one work? Motor is 1982 Mariner, 30 hp. See attached photo. Black connector is labled as for "Yamaha & Mercury, 1998 and newer style engines."
When hooked together, the black connector from the hose sits at a small angle (10 degrees?) to the base of the connector on the engine (again, see attached). The hose connector is furthest away from the base of the engine connector at the fuel inlet prong. It seems like the locking prong needs to be slightly larger diameter, or, that the spring that pushes against the fuel delivery prong is so strong it pushes the connector out at an angle.

Based on the recommendation of the nice lady at West Marine, I also brought home a connector that was labled as for Yamaha engines. Both receiving holes on that one were too small in diameter to receive the prongs on the engine. However, the lady at West did let me know that people sometimes take multiple connectors home and return the ones that don't fit, but sometimes in the wrong package - so I shouldn't count on the package lable as representing the actual contents.

I should add that the brass fitting is actually a tank fitting - but the black connector sits on the engine fitting just as shown in the photo. As a further complication, the brass fitting was purchased at WalMart and listed as for "Use with Yamaha brand motors."

Anyways, my basic question is: does the attached photo represent a normal fuel hose to engine connection and will it function without leaking? If I have the wrong connector, what one do I want (there don't seem to be any in the stores I have been in that are listed for 1982 Mariners)?

Re: Do I Have the Correct Fuel Connector?

After reading some additional posts, I'm thinking of eliminating the issue by removing the connector on the motor and using a direct hose connection to the motor's fuel system.

Since my boat has not been (and will not be) used on a regular basis it's been my practice to run the carb dry after each use. I'm assuming that, with a direct hose connection to the motor, if I disconnect the fuel line at the gas tank I will still be able to run the carb dry. Correct?

Also, if I go with a direct connection, what's the hardware look like? My initial thinking is to make up (or purchase) a union with barb connectors on each end. One barb would go into the hose that would be removed from the motor's quick disconnect and the other barb would go into the hose coming from the external fuel filter. This would allow me to easily pull the hose connection apart if I wanted to remove the motor to take it in for service. Would this be the way to go? Would receiving a motor with no quick disconnect, only a hose barb protruding from the motor, puzzle the mechanics? Or do they see this all the time?

Re: Do I Have the Correct Fuel Connector?

I would think a 1982 Mercury would have the bayonet-style connectors. Isn't there a male bayonet on the motor now? You can use whatever connectors you want, as long as they are matching male/female sets.

You can eliminate the connector at the motor. When disconnecting at the tank, you'll just have to run out the carbs a little longer, by whatever volume of gas is in the longer line, primer bulb, any fuel/water separator you have, etc. (If you do have a separator, that can be a lot of gas, so if you do have that maybe not a good idea.) I would not bother putting a double-ended barb in there, if you ever have to dismount the motor just disconnect the line at one end of the primer bulb.
