496ho Fuel System?

[GHT]

Does anyone know it very well and can anyone provide a diagram. There is a part on the back of the motor and it has two (2) larger hoses at each end and two (2) smaller hoses coming out of the top. What are they and what do they do???
Damn There are a lot of fuel lines and / or vacuum lines. What is what??:confused:
Thanks.

Larger hoses should be cool water coming from your sea pump on the way to the water pump. You should have three fuel lines, one from the filter to the pump, one from the regulator to the fuel rail and a return line from the regulator to the fuel filter again. You should also have a vacuum line from the manifold to the regulator. The older fuel cooler/pump setups didn't have a return line so you would only have one line from the filter and one line to the fuel rail.
Fuel comes from the filter, to the pump, into the cooler, through the regulator, to the fuel rail on the manifold (or bypassed back to the filter), into the injectors, and ends up as black soot on the back of your transom.:D

The cooling tube at the back of the motor is for the power steering/hydraulic fluid. I think if you trace the line from the pump it will go to that cooler...

That probably is what he's looking at. :idea:

Okay. The link the Rick put me to helps. At least now I know where the fuel filter is (inside the assembly to the lower left side of the motor). I followed the two lines from there to a junction and from there to the back of the motor.

So, what is the part at the top left corner next to the clamp with a #2 next to it. It is the dotted part?

Power steering cooler

Thanks. So if I wanted to change the fuel filter all I have to do is remove the three screws and then pull the filter out.?.?, Right? Or is there anything else I should know?

Here is all the CRAP I took off my 496 when I went to a bigger custom oil cooler that mounts to the back of the motor. Cleans things up a bit.

Holy crap.. That is a lot of parts.. I need to change the fuel filter but I'm unsure what it will involve.
