Suave,
I've been trying to pull together some info of late about the windshield washers in order to write up a guide document. It's been (bloody) frustrating though, as there appears to be very little info out there (with a few exceptions, I have struggled to even get guys to send me photos of the washers installed in their cars
).

Anyway, I do have some info on the squirter nozzles.
A variety of nozzle were offered for windshield washers:
• FE and FC Holdens with vacuum washers used part number 7406027
• FB Holdens with vacuum washers used part number 7406569
• EK Holdens with vacuum washers used part number 7419027
• FB and EK Holdens with electric washers used part number 7421873
The original FE and FC Holden nozzles are sort of a cone-shaped affair, maybe 5/16" across, with a threaded section at one end and a pin-hole in the side of the top. The top of the 'cone' has a hexagonal head, reminiscient of the screw-on fitting at the end of a capuccino frother on an espresso machine (not my description, but graphic none the less).
Some options are available to replace the original nozzles.
Legend has it that many British vehicles have washer nozzles that will fit early Holdens. However, not all fit (MGB for example do not). Rover P6 nozzles will fit into the FE, FC or FB Holden windshield wiper pivot arm spacers. The barbed connection is carefully cut off with a hacksaw, after which the nozzle will screw directly into the pivot arm spacers. The P6 nozzles are available from Mark Richmond at
dmspares@internode.on.net.
A further option involves modifying the Holden windshield wiper pivot arm spacers (the "Malcolm squirter mod"). After removing the original grub screw from the pivot spacers, they can be drilled and tapped to a 6mm metric thread. A grease nipple is then fitted after picking out the check-ball in the end of the nipple. Different angle grease nipples can be used to align the spray pattern on various parts of the windshield. This involves a bit more mucking around though.
You don't have to remove the plenum cover grille to fit the pivot arm spacers for FB/EKs (it's easier to do so for FC's though...), but you will probably want to replace the rubber gaskets between the pivot arm spacers and the body.
There are also a few tricks to putting the hoses onto the copper pipes. It's easier to connect the tubes to the pivot arm spacers, then install the spacers rather than trying to contort yourself up under the dash. When the water (pressure hoses) are connected to the windshield wiper pivot shaft spacers (for FE, FC and FB Holdens), the hoses run inside the cabin, before passing through the firewall grommet and connecting to the pump outlet. By having the hose/pivot arm spacer pipe connection inside the cabin, there is a potential that any leaks can spray the back of the instrument cluster or glovebox. This is particularly a risk if the water hoses are just slipped on to the pivot arm spacer pipes. Access to the connection is tucked right up under the dash. Some options for ensuring a good seal are:
• Using silicone to seal the water pipes to the pivot arm spacer tubes. This is best done by taking the pivot arm spacers off the wiper assembly and fitting the tubes/silicon off the vehicle. The tubes are then passed through the cowl as the pivot arm spacers are refitted.
• Using small hose clamps, fitted from under the dash. Not the easiest thing to fit upside down in a confined space...
• Fitting a barbed end to the pivot arm space tubes (the "Ed Ho squirter mod"). The barbed ends can be sourced by buying a 4mm plastic barbed tee or cross fitting used for garden watering systems (from Bunnings or nurseries). To fit the barb:
1 Place the tee or cross fitting in a vice and drill out the barbed end to suit the outside diameter of the pivot arm spacer tubes (use a drill of 1/8” diameter). It’s a lot easier to drill out the fitting before the barb is cut off.
2 Cut the barbed end off the tee fitting and slip it over the pivot arm spacer tubes, using some superglue to hold it in place.
3 Use 4mm garden watering system hose (also from Bunnings or nurseries) or 4mm vacuum hose to connect the pivot arm spacers to the pump.
Hope the above helps, and maybe gives some guys an idea of the kind of info I am looking to share in the document.
