Fuel line and fittings

so instead of putting the braided line straight on the sending unit, you want to add a connection to a hose barb?

this is what I would use IF I wanted to do it that way
Compression 1/2" OD to 1/2" Hose Barb fitting Transmission Cooler Line | eBay

but between you and me, i would go this route

1/2 HARDLINE COMPRESSION FITTING TO 8AN 150 PSI | eBay
put that on the sending unit, and then put an -8AN on your braided line
