On a M38, is the fuel line from the pump to the carb 1/4" or 5/16"

It can be a tough one to find in the IPL. Sect 306 Fuel Tank & Lines. on page 83 WO# 801380 ORD# 8673504. 1/4" OD steel with .030" wall. It is serviced in the field with 1/4" OD copper, .030" wall.

Note that there is a TB 9-804-6 that covers repositioning the line to prevent vapor lock.

Thanks for the info. I had looked and looked, and wanted to make sure the 1/4" was correct. Thanks for the TB as well.
