Inlet Size (Inches):3/8
Return Size (Inches):5/16

Napa also sells the 12" line (with push style connectors on each end) that connect this filter and the stock fuel line to the LS1.

The filter has a 3/8 inlet port and a 5/16 return port on one side, which will be fastened to the stock Porsche hard lines with compression fittings. Connect the 12" line to the OUT TO MOTOR side, and plug the OEM rubber fuel line into the line and up to the rail.

12" fuel line repair pipe with push on flares - $10
2 x 3/8 hard line compression fittings - $5
1 5/16 hard line compression fittings - $3
