I think I slept through the class about removing the sediment bowl on the fuel pump on my '37 Master coupe.
Is there a trick to getting the gasoline out of the bowl before you remove it?
This weekend I wanted to clean the sediment off of the top of the fuel pump. I shut off the fuel at the tank and let the engine run out of gas. My initial thinking was that this would pull the fuel out of that bowl. As I watched the bowl while the engine was running I realized the major flaw in my logic . (Not the first time for that either.)
Fuel enters the bowl from the bottom and is pulled out through the screen at the top. So the fuel level in the bowl remains at an almost constant level to the bottom of the screen. Even with no fuel flow to the pump it will not pull fuel up and out of the bowl.
I just wrapped an old rag around the flange of the pump and opened the bowl. It is not a lot of gasoline so the rag caught it all.

To get the fuel out of the bowl just remove the glass bowl and the fuel will spill out. In you do not want it to spill on the garage floor put a drain pan under it. To days gas evaporates in a few minutes, To remove the screen pull up on it.
Good idea to have a new gasket available. Years ago the gasket was cork and changed to a gas resistant rubber later.
I have the engine pans on my car so I let the gas get absorbed in a rag. I just was hoping there was a trick to avoid that.
Yes, I have a continuous free supply of very fine rust particles from the fuel tank. That is why I wanted to clean the bowl area. I have a Fram G2 filter right at the tank outlet. It catches most if it. I keep an eye on it and have to change it about very 1000 miles.
I have had the tank cleaned twice. There is no external rust on the tank. That is a big advantage with the coupe. The tank is within the body so it is not exposed to the weather or road conditions.
I expect that eventually I will have to replace the tank. I will do that rather than try to seal this one. I have heard enough mixed reviews above tank sealers that I won’t spend the money to do that.
