Two of these were a perfect replacement for the rotted cork float in my 1929 DeSoto. ACS isnt just for planes, I use them often for all of my vintage race car needs!

So Far my purchase seems to work properly it has been described properly and I am very pleased that I could fix some thing myself that a manufacture wanted me to spend $350 to buy a whole new fuel pump and fuel pump sending unit. I save myself a lot of money

This fits perfectly in my metal OMC (Johnson & Evinrude) 6 gallon tanks from the 70âs. Isnât that a hoot, buying car parts from an aviation distributor, for my boat. Pilot, A&P I/A, owner of Cessna 172F, 1929 Dodge Brothers, and a 1976 Starcraft boat so Why Not

This float solved my problem 100%. The fuel gage in my Boston Whaler Outrage 19 sat on zero. The problem as I suspected was with the float on the 30 year old Rochester Gage. It was originally cork and was saturated so it would no longer float. Your neoprene float fits perfectly and will last longer than the life of the boat. Thank You Aircraft Spruce.
