Have Boat Questions? Ask a Boat Repair Expert.
Hello, my name is***** will assist you.
Is the #2 plug more black that the others?
Is the throttle butterfly still getting to wide open throttle?
Was the fuel checked for water?
Does it idle well?
Ok, are you near the boat now?
Ok, look at the fuel line from the boat to the engine. It is gray with red writing?
Can you remove the fuel filter and look inside the chamber for signs of debris?
Was the chamber looked at inside it. I am looking for certain signs.
If there is debris in the chamber, it is also inside the low pressure pump. that is why I am asking.
the fuel rail? Close to $1000?
Any luck on the fuel filter?
Do you have a pressure gauge that can read at least 50 PSI?
Sorry for the delay, I had back to back phone customers.
Ok, I am not stumped, I just need you to look at the things that I recommend to you, weather he has already done so or not. I am not a part changer, I am a tech. I locate the problem before ever telling you to replace a part.
So can you take out the fuel filter and have a look inside the bottom of the chamber?
for a pressure gauge, you can go to most chain auto parts stores and rent one that can read over 100 PSI and we can use that to do all of the testing that I am going to need done.
Ok, I am in Arkansas so I understand.
With the gauge. Hook it to the fuel test port on the fuel rail. Use the primer bulb and pump it until it is firm. Turn the key on, watch the fuel pressure on the gauge. I need to know what it maxes out at and where does it hold when the pumps turn off.
It should be the lower one on the fuel rail. the hose coming from the back of it, should go to the VST ,fuel pumps, or the left of the engine.
The 60 PSI gauge is fine for this test.
No, the one on the fuel rail that the hose in this pic runs to.
The upper test port on the fuel rail.
Great, volume test is good. What is the pressure reading at the back of the VST?
Did you look inside the chamber for the low pressure filter yet for any debris?
Yes, pressures look good.
If you cranked the engine for a minute with the water hose connected to it. Then pressed in on the air test port on the fuel rail. Do you get any liquid at all out of it?
Out of the bottom test port on the fuel rail??
You can do it after cranking the engine a few times with the water connected.
Fuel smell or water?
thats good. not supposed to be any fuel there.
Look at the front of the VST. The pulse pump is there. Remove the hose from the front of it. then remove the two blots that hold it to the housing. Rotate the pump slightly, use the primer bulb and see if there are any leaks from the front elbow or from the hole in the back of the pump.
Alright. Talk to you tomorrow.
