I have a question on the routing of the vacuum tubing to the fuel pump from the intake manifold? Does the tubing go to the port marked in on top of the fuel pump?

Does this help?

It looks like the tubing closest to the block is going to the wiper. That is the IN port on my fuel pump. Thanks for the picture.

Thanks for the photo. The IN port does go to the wiper motor.

I have a fuel pump that looks like that but isn't marked as far as what goes where.
Hope it's the same?

Is yours marked AC?
It should be the same. Do you have a vacuum gauge?
The vacuum pump only comes in when it senses low manifold vacuum to operate the vacuum wipers at low manifold vacuum (WOT). Hook manifold vacuum directly to the motor intake line (with extra vacuum hose) and verify the motor is working correctly.
If so and after connecting vacuum pump back into the circuit, again verify motor operation and then take it out and gag it to see if the vacuum pump is operational WOT.
Hope this makes sense...

Pertaining more to the wiper motor but a friend with a 56 did the oil/lubricant trick with the wiper motor, after it sat for a day removered the arms and blades, turns on the motor for the summer letting it run all the time. This really worked for him and the wiper motor now works perfect. Seems like not using them hurts their operation.

Did he use brake fluid or a light weight oil?

Marvel mystery, because he was worried about the problems u could have with brake fluid leaking around the fittings inside under the dash. He said he worked the blades back and forth 2-3 times the day it sat. He said the car smoked a bit when starting but kept the wiper motor in the on position for a couple of months. He didn't put the arms and blades on during that time at all. He told me he put on acorn nuts wedged on with tape as not to hurt the splines.
He also said a few times he heard a noise when driving he couldn't figure out, then remembers the wipers were on.

Thanks. I'm going to give it a try. I have a rebuilt wiper motor but this sounds way easier than laying upside down on the seat replacing it.

Really appreciate all the info you are kind enough to provide

Forgot to add:
Pump is unmarked. I do have a Mighty Vac pump, but no gauge

I have not started the engine since I began this post. I did have 17" of vacuum . My cam is a Isky E-2 very mild. I have a A/C vacuum pump and used that to run the wipers. Wipers worked good. The deal here is I have had 2 fuel pumps stop working on the wipers both bought at O'Reilly Auto Parts. Neither pump had any markings other than the IN on one port. Also note that the wiper motor has been rebuilt. Once I get the car outside and running we will see what happens.

Newport Engineering sells a very nice 2 Speed Electric Wiper Conversion along with an Extension which allows use of original Wiper Knob. You can buy direct from Newport at least expensive Price.I have had One on my Sedan for Years with no problem. Ordered One for my "New" Convertible. If You change to electric You can change Fuel Pump to early 60"s Ford Truck Pump with Fuel Filter Can. Much more reliable than the Go Slow uphill, Go Fast downhill original Wipers.
