1954 235 Fuel Pump
Hey folks, I have the flat top fuel pump on my 54 - 235.
The body has the 2 valve chambers separated by a partition. The cap has matching (smaller) chambers with a matching partition. The rubber gasket between these is a solid sheet isolating the upper smaller chambers from the lower valve chambers. Is there a purpose for this isolation ? Maybe the air trapped in the upper chamber is a buffer ? or snubber of sorts ? Just curious, thanks for your time.

Re: 1954 235 Fuel Pump
No prob, got this one figgerd out ... once I learned what to search for.
"Pulsator" gasket. Acts sort of like a smoothing capacitor in an AC electrical circuit. Absorbs the shock, cushions the pulses and actually reduces the noise of the pump. Kind regards,

Well I learned two things out of that. How that pump works and that Fred is getting pretty good with hitting the search button.
