its a damper i have the same thing in my 810 .. i have removed the damper befor from the car to see how it would flow and its all pulsy with out the damper.. even so no need to crack your brain over it it can also be a damper / check valve .. but if your pump goes out dont wory and just get a universel external pump and hook up the damper if you wish its all good eathier way..
also my 77 810 always has some presser in the lines when the car is off.. (ive had fule spray in my face/eyes .. lol )
Hey Fabian, Went to your 810 site......NICE!
Hey do all the members of this form live in CA ??
Thanks for the info.
What do you mean when you say "it was pulsy without the damper". How could you tell?? Can you describe what pulsation you observed. Was it Bad ??
According to the fuel pump diagram above the 810 also has a fuel damper: PN 22675,attached to the fuel line. This fuel damper, I would think would absorb most if not all the fuel pump pulsation.
Hey Fabian, Except for the games you and me have the same interest, cars, food, and women....what else is there.
My car has an inline fuel pressure reg. and a fuel damper, so, I thinking that I do not need the Pulse Damper attached to the fuel pump.
The Fuel pump is going into "maybe" a "72 FI Mercedes. It has all the specs I need: pressure and flow, but the Pulse Damper and its operation is what I need to understand. Once I got some good understanding of the PD then I will decide if it is worth keeping or removing it from the fuel pump before installation.
