I have a 450sl 1977, chassis 107. I believe the fuel accumulator is the problem. Will start but takes a number of turn overs and pumps of the gas. The warmer the car is the worse the problem. same problem for a year with no worsening. Fuel pump, hoses, distributor cap, plugs just replaced with no change.
I can't seem to find the part for this year and chassis.
Any thoughts are appreciated.
