I just dropped a 454 bb into my 81 does anyone know if there is anyone that has the 81 fuel lines pre bent in the 3/8 size? Im sure it should be change from the stock 5/16 lines. Thanks in advance

 

npd makes all lines in the 3/8

 

Considering the cost, I'd buy a bending tool and the line, and still be cheaper. Plus you'll have the tool afterwards for future tube bending. A 25' roll of line is about $16, and the tool at Harbor Freight is about $6-$8.
I actually enjoy bending up fuel and brake lines for project cars.

 

Awesome thank you for the info I may just get the tube and do myself
