Merc Fuel Lines

[FloatsLikeARock]

2000 Mercury 125 ELPTO. It's got what I think is a fuel starvation problem that is driving me crazy. It only manifests itself when I get about two miles from the launching ramp. The engine intermittently loses power and dies. It can be restarted immediately, but the problem will recur minutes or seconds later.

The fuel tank is properly vented. I'm wanting to test the fuel suction line between the fuel tank and the engine for leaks, and the pressurized fuel lines and filters in the engine for clogs. Yes, I'll also be looking at the fuel pump. I see that all the hoses on this engine are secured by zip ties. Before I start cutting these zip ties and pulling hoses off, I thought I might need to know what I will need to put the fuel system back together properly.

Questions:
Will some standard size of automotive fuel line be okay for this application, or do I need special line?
Will standard worm drive or spring type clamps be okay, or do I need special zip ties and installation tools to install them?
If there are clogged or suspect filters, will standard automotive inline fuel filters be okay, or do I need special filters from the mother ship?

Marine hose is fire rated. Automotive hoses are not. Once inside the motor housing, you can use whatever you can find

While worm drive clamps will work in a pinch on the larger hoses, they are notorious for vacuum leaks.

Proper tie wraps clamps are the only way to go with the spaghetti tubing on the motor.

While there is nothing special about marine filters, automotive and marine systems don’t require/use same level of filtration. A good quality, 10 micron coalescing filter is the way to go in a marine application

I have the same motor and had the same problem at the beginning of the year the fuel pump was the problem with my motor I will suggest a fuel pump rebuild but please buy the OEM equipment as I found out the hard way with mine the cheap rebuild kit that I bought online worked good for about 3 outings and the same problem reappeared due to the round black rubber peace's swelling up from the gasoline another must-have for this particular motor is a fuel filter between the tank and motor because garbage from fuel tank can enter the pump and reduce fuel pressure because mercury decided to install the fuel filter after the pump which makes no sense whatsoever this engine has 1of the poorest designed fuel and filtration system of all outboards that I have ever owned
