Barry, I'm on my 3rd season on our 3YM30 and have 450 hours. Can't say that I've even noticed if there was one or not. I'll try to remember to have a look this weekend.

I notice the difference when looking at my friends engine...exact same model...

If you were going to try to "fix it", you should certainly be able to read the manual. Look at the fuel system diagram. It will show you how Yanmar wants it done. Then, you will be able to talk to the yard intelligently and they won't be able to BS you. I assume the engine is still under warranty? If so, and you alter the installation, you can void the warranty and/or affect any legal remedy you have against the yard if they did screw up. Looking at the manual and calling the yard may save you a trip to the yard altogether! You will have learned something about your boat, and you can go sailing instead!

I'm installing the fuel line for my Yanmar 3gm30, is 1/4" fuel line the right size?

Barry 33 (the OP):
What was the outcome on this return line issue? Did you ever come up with any answers from "the yard", Yanmar or your manual?

I would think the fitting you are attaching the hose to would determine it's size, but your Yamar dealer could certainly tell you. Make sure you know what you are doing. A nice Yanmar is a terrible thing to waste!
