made my own gaskets out of manilla folder material...! used the old ones for a pattern, cleaned the thing up, repacked with silicon grease... closed it up and tried it out before putting it back on the car... worked fine... still wonder if I just don't have enough vacuum to run them...

This might help some one before I put my wiper motor in my car I tested it by putting it on a air conditioning vaccume pump and it worked good of course with no load on it and when i installed it it works fine. When you rebuilt your pump where did you get the gaskets?

thanks for the ideas...

to respond,

-stock cam

-no tomatoe can

-new fuel pump with two ports on top, one marked "wiper"; I have this one plumbed to the wiper motor; the other port is plumbed to the intake manifold

guess I need a vacuum gauge to check my amount of vacuum and see if its in fact too low to operate the wipers.

I can put one wiper arm on and it almost works... just seems like I need more "ummph" from the vacuum supply...

I thought brake boosters had their own vacuum reservoir and a check valve in the 3/8" vacuum hose that supplies it.  I also thought the tomato can was for the heat/air cond. system so that it wouldn't switch from cool to hot when you stepped on the gas.  Seems the tomato can only had a 1/4" feed hose, which isn't much to supply vacuum to the brake booster.  Guess I'd better check my manual and see if I'm thinking correctly.

If you don't have one, you might try a dual-action fuel pump.

Did you ever look under the hood and see a can, usually black, that looks EXACTLY like a big tin can?  It looks like a big V8 or tomato juice can so that's what we call it.

I guess you can say it's an old term.  We started using them with the onset of power brakes.  They accumulate vacuum so the brake booster still works for a few pumps, even if the engine is off.  They can do the same for your Trico motor.

Vacuum can.

Check that you don't have a collapsed or obstructed vacuum line. Also, is your cam stock or near stock? Aggressive cams often have low vacuum. Is the fuel pump vacuum diaphragm working o.k.?

Install the tomato juice can with a check valve like power brake units have.  You can put it anywhere, but preferably close to your Trico unit.  It will sustain good vaccuum for a little while longer, through accelleration.  Hope this helps.
