Inside motor fuel line replacement help needed.

[paleojoe]

Engine is a 2005 Mercury,90hp, 3cylinder.The fuel line that runs inside the motor has split and I can not seem to find a part number or what it is called on line. The line has a outlet in it that is plugged off, then it branches off in a Y. Looks like one goes to high side and one low? I have it so it will work now, but want to replace it with the correct line. Thank you for your help !

This is a very good site for diagrams/parts for Mercury/Mercruiser. To better find the right part, you need your serial number:

What I do is use this site to get the part number, then search for it online (eBay, etc.) to find the best price.

If you're dealing with bad fuel lines going to or coming from your fuel pump, you should consider disassembling the fuel pump. The rubber membrane inside is susceptible to deterioration from 90/10 gasoline, and I'd suggest replacing it as a maintenance item.

As you can tell from the picture, fuel pumps are pretty simple animals. There's a hole on the back that gets pulsating air from the crankcase as the engine turns over. It pushes the rubber membrane in and out sucking the gasoline through the hoses.
