Fuel Pump Inlet

[TomMcCauley]

While many of the topics on this forum can be challenging issues to identify what's going on, this one is simple....My Response is whining and leading me to believe I either have a fuel pump that is going or a restriction of the fuel. I have been advised here prior to inspect the screen on the inlet side of the fuel pump for debris. Problem is I don't know which of the two lines going to the rear of the boat is the inlet. From this picture, can someone please tell me which is the line I should remove to inspect the screen? Do I want to remove the hose clamp to inspect or the fitting?

Thanks!

The screen will be on the hose connected to the pump on the 'left' side. In your picture, it is the one with the hose clamp you can see. Have a container to catch the fuel that will come out when you disconnect the line, and use an inspection mirror to look up in there and you will see the screen.

When you disconnect the line, 'aim' it down into your catch container, because if you have debris in there, it may have 'sunk' down from the screen into the line, only to be sucked up into the filter when the fuel is flowing.

I used a small glass, the kind you would serve a mixed drink in, so that I could more easily inspect the contents of what came out of the hose and drained down from the pump. I had a chuck of what appeared to be fuel line clogging my pump.

To find the screen, do you just take the hose off of the fitting (loosen hose clamp and pull off hose) or do you need to remove the actual fitting from the fule pump?
