I went into the local car parts place the other day and ask for submersible fuel line............
The got a puzzled look on their face and thought I was kidding.........
Do you know how to tell the difference by the marking on the line?
Most fuel lines will carry a SAE designation......most fuel line in the stores is SAE 30R7 which is general purpose.

In tank submersible will be marked with SAE 30R10.

Having the right fuel line will eliminate a lot of headaches down the road.
