Fuel Supply Line...

[avazquez]

Should the engine and the generator have separate fuel supply lines? Can they share the same diesel supply line?

Our generator has a separate supply line and does not pass through the primary fuel filter. It draws from one specific fuel tank. I would think two engines pulling from the same line could require more fuel than one supply line could take if they were running at the same time.

So you have two separate diesel tanks?

[sailingdog]

I would have separate lines for each.

It would depend on the requirements of the 2 motors. Size of line and line pressure. But the easy way out without doing the math, run 2 lines and be safe.

You could branch off the line, I reckon. But remember that a leak on either one will stop then both. A pressurised fuel line would avoid that, I am sure.

A separate fuel line may not be easy to fit. It normally means drilling another hole in the top of the tank, and that is not always easy either.

If you do drill another hole, put a wee bowl in the tank beneath the hole you are drilling with a wee bit of water in the bowl to douse the heat of the drilling swarf. Let's not take any more fire risk that we have to.

Never try that on a gasoline tank.
