Troubleshooting ignition coil 5.0 Mercruiser

I can do that and also I’ll make sure the soft fuel line isn’t collapsed

should not be any soft fuel line. there is the A1-15 fuel line from the tank to the filter and steel lines from the filter to the carb.

you cant crush A1-15 without a vice.

Mine definitely has a soft rubber fuel line going from tank to fuel filter housing

 

[WrenchNhammer]

I’m gonna get out there shortly once I eat

 

[Bt Doctur]

need to verify it first, its inside the fuel pickup tube in the tank.

 

[WrenchNhammer]

So if my boat has a soft rubber fuel line where is the anti-siphon located. Taking a remote fuel tank with me

 

[WrenchNhammer]

Makes sense, when the problem presented itself, it was running low on fuel

 

[Bt Doctur]

its the first fitting on the tank, looks just like a barb fitting but a bit longer

 

[WrenchNhammer]

Also, I mentioned it has a new fuel pump. That’s because the old one quit pumping….

the anti siphon valve is the connection nipple on the top of the pickup tube.

Once I pulled the fuel line off I noticed something inside it and pulled this out. The guy at ORieleys said it looks like a fuel line inside a fuel line

 

[WrenchNhammer]

I don’t know how, but it still backfires and runs terribly

 

[WrenchNhammer]

Didn’t mention but was using a remote tank. Maybe the carburetor is my problem

 

[WrenchNhammer]

Saw what looked like water in carb so I took the separator out emptied it and refilled with good fuel. No problem however it did overheat. I was revving it up a bit do you think that the muffs aren’t meant to be used in this matter? It has a new impeller and thermostat

the water separating filter is a one-time use. you cant simply empty and replace.

that does not look like the proper A1-15 fuel line. and no, ORieleys would not have USCG approved fuel line.

 

[WrenchNhammer]

It’s running good right now but overheated. Not getting a good seal on muffs. Gonna put it in the lake and try it out

 

[Scott Danforth]

if your hose in on and you have good flow (getting a 10 foot spray from the muffs) it shouldnt overheat

 

[WrenchNhammer]

I wouldn’t say 10’ spray but definitely getting a bit less. I’m losing quite a bit of water around the seal on muffs. Seems like they used to fit tighter…
