smillard Posted November 23, 2012 Share Posted November 23, 2012 Any idea where the vacuum source is for the wiper motor on a 37 81 series?The intake only has 2 vacuum ports, one for fuel pump, the other for starter switch. Link to comment Share on other sites More sharing options...
37_Roadmaster_C Posted November 24, 2012 Share Posted November 24, 2012 Smillard,The wiper vacuum source is on the fuel pump. The 37 320 fuel pump is also a vacuum pump to help even out the vacuum to the wipers. The connection is on the lower part of the fuel pump inline with the intake manafold connection just toward the engine block about an inch.Robin Link to comment Share on other sites More sharing options...
