Does the main motor being a fuel injection come into play? thanks !
If you have a fuel water separator filter, which you should for obvious reasons, there should be an extra outlet port on the filter housing with a screw in plug. Make your connection there and eliminate any potential problems tying into the main motor fuel line such as vacum lock. You should be able to remove the fuel line connector that is currently on the portable fuel tank or get a new one for a few bucks and assemble/plumb it to the fuel water separator filter housing.
