I am in the process of doing a total rewire on my center console. The boat came with mercury k planes 280. I want to make sure the wiring from switch to pumps is correct and also hoses are connected to the correct port.

If power is applied to the blue wire on pump should it extend the tab?

If power is applied to the blue which port should the fluid flow from at the pump?

Any diagrams available?

Also where is best source to purchase new hoses?

Thanks for any help

Blue wire = tab up
Green wire=tab down

Vintage. Thanks for the reply.
What about the hoses?
I would think that with power to green the tab goes down like you said , so fluid should flow out of which port?( high pressure or low pressure)

I want to replace the hoses too, any recommendation on where to get them?

Thanks

Down is high preesure

If you're looking for hoses contact paragon performance, they can custom make you any length hose with any angle fitting you need. Just had Afew sets made by them and the quality is great, all stainless construction and the price was cheaper then any premanufactuered hose by a considerable amount.

Ok thanks for all the help.
I was told that blue was for high pressure and green was low. That is where the confusion is .
