Steel fuel sender float

It's interesting to discover some of the
changes made in manufacturing materials
during the WW2 and Korean war era.I have
seen a steel radiator and now I came up
with a steel fuel sender float. This is out
of a Signal Corps 10 KW generator dating
from somewhere in the middle to late
forties. Brass was being used for more
important items than gas tank floats at
that period of time so this is what some of
the gas tanks ended up with. I filled the
tank with a 10% muriatic acid/water
solution for four days, sloshing it
periodically. The tank cleaned up slicker-
n-a whistle but the float didn't fare so
well. It was probably rusted through
anyway. A new brass float will be here in a
few days.

fixerupper: How did you prevent the flash rust that usually follows the use of muriatic acid? Did you coat the tank? Just wondering, I have a tank that's beginning to exhibit enough rust that I am going to need to address it sooner than later. gobble
 
There was a little flash rust in one spot before I could get it dried out. Not much but it was there nonetheless. I rinsed it five times with hot water, then stuck an air hose in there to dry it quick. Maybe a shot of phosphoric acid would handle it? At first I wasn’t planning to coat it but now that I see how clean it is I might go ahead and do the coating. This tank has two baffles and it’s only ten gallons so coating it will take some finesse.

The sender was rusted tight but I got it freed up without damage. The copper resistance strip in the cap is hardly worn as is the brush that rubs on it as the float moves. I have good vibes I can get it working.
 
Had a radiator ro
a middle 40s combine that had steel top and bottom tanks.

























Had a radiator from a middle 40s combine that had steel top and lower tanks....looked like a screen they were so full of holes.
