1/2 inch Fuel line and Sending Unit

[cp72ss]

Hello,

I'm looking for some help on how to modify my Gas tank Sending Unit. I have run 1/2 inch Hard Fuel line from the Tank to the Fuel pump. However I realized that the Sending Unit I purchased a while back is only 3/8.

Here is a picture of the sending Unit.

My questions are:
1) What would be the best way to modify the Unit to 1/2 inch?
2) this may be a stupid question but I'm guessing that I need to do the modification or the 1/2 inch fuel line is useless?
3) Can you buy a sending unit that is 1/2 inch? I’ve looked at the normal restro places. Original parts group, NPD, Year one etc. and didn’t see one.


Any suggestions or help would be appreciated
Thank you
Chris
