Hi guys,

I installed a double action fuel pump on my M38 for vacuum wipers. I wanted to know how I could run the pump without installing the wiper motors, because I wanted to get the engine to completely run before I start digging into other accessories. I am guessing that I close off the vacuum line.

Thanks,
Harsh

Actually the pump has to move some air all the time. It's hard to advise without seeing what plumbing you already have in place. Just add filters to each of the two unused ports. or if you have the vac lines installed from the intake manifold and to the wiper "T" just install a vent cap in the wiper "T") port to the wipers The little rear axle cover vents with an 1/8" P thread work just great for that.

Thanks for the info. I am doing a ground up restoration so currently the engine sits on a engine stand. I want to mount the engine onto some feet and get it started before I put it on the frame.

I will go ahead and order the filters.
