Fuel / Gas Sending unit question

Most of the stainless units are made in China by Jesse Lai. There are decent OE replacements coming out of Canada from Spectra Premium, and there are even better genuine OE units still available from Chrysler (P/N 4051 004). 5/16" line is correct, and the type with the vapour return fitting is OE only on '75-6 models with vapour return. Handy (in conjunction with a vapour-return type fuel filter) for combatting hot-start problems with modern alcohol-contaminated gasoline, but not the only way to retrofit same. Brass or plastic float is fine. YES, you need a strainer!

Individual parts for repair or in case the sender you buy comes without:

Float: Ford P/N COAZ-9202-B
Strainer "sock": GM P/N 5651 705
Gasket: Chrysler P/N 6031 475
Sender grounding clip: Chrysler P/N 2258 862
