Another sending unit ?
« on: February 11, 2017, 04:59:06 PM »
Fast Fred helped me find a sending unit to fit my new tank. After receiving the new parts I pulled the tank on my 1979 Pinto. The old sending unit has two fuel lines I am assuming that one is feed and the other is return. The new sending unit has only one line for the feed.
Can I use just one line or do I need a return for my system?
Thank you in advance!

the sending unit you have is for an early pinto , single outlet ,  after market part number FG178A ,   the One you need is FG178B  it has two outlets ,   the extra tube is a return from the fuel pump , it suppose to prervent vapor lock in hot weather , so if you live in a cool area and does not get over a 100 degrees you just could plug the small pipe one the fuel pump or just change to a fuel pump that does not have it  ,  hope this helps you
