Brian,
The original SW rebuild sheets state that the intake valve should be finger tight, then one quarter turn.
Over time, i've developed the following modus, when testing switches.
1.Unscrew the intake valve and set aside.
2.Insert finger into bottom of piston tube and by viewing thro the switch access hole, let the piston and spring drop so that the 'cut out ' in the piston is in the correct position to install the switch.
3.Install switch, remembering to push the actuator arm to the up position.
4. Install the intake valve, finger tight.
All the above should be done with the pump body horizontal on the bench.
Dont bother with the filter and bowl until you get that sucker to kick continously.
By the way guys, a point you may not be aware of.
If the piston tube moves laterally, it means the hidden seal at the base of the piston tube has shrunk. In most cases, using an appropriate tool ( i have the original SW tool ) you can re stake the tube . Failure to do this, will allow fuel past the piston tube base and into the switch area. Not a good idea.
Finally, one example of the latest batch of pumps i've totally refurbished.
Replated, new gaskets & seals, new top boot,rubber mounting strap and new oem switch wire.
