Heating Hoses

I haven't had much time spent on the GD lately, but I have managed some bits and pieces.

I finally connected up the heater pipes using stainless jubilee clips including the Ford heater control valve.  I haven't done the run up to the heater box as I will wait until the body shell is on to locate the pre-made pipes.

Fuel System - Continued

I made a bracket to hold the fuel pressure regulator out of 2.5mm thick stainless.  I left a side cut out in it to aid removal of the wiring loom where it passes through the bulkhead.  I then finished off the fuel hose fittings to ensure they fitted correctly from each fuel rail.

I then drilled a larger hole in the air inlet to fit the Inlet Air Temperature sensor.  A 16mm grommet was used.

Sensored!

I decided to over complicate my Oil Pressure & Oil / Water Temperature sensors for the gauges.  I thought it would be a good idea to have the possibility of having the measurements input to a data logger of some kind.  I opted to buy sensors from GM that have dual circuitry.

They have 3 pins.  One pin is for the gauge, and the other two pins are for a 5V signal into an ECU / Data Logger.  I thought that this would future proof my install in case I wanted to add the data logging function.

After surfing the net for a while, I discovered that the correct part numbers were:

Oil / Water Temperature Sensor (3-Wire):  GM#  12551708
Oil Pressure (3-Wire):  GM#  12616646

These have the correct threads / sealing washer to be able to screw straight into the LS engine without any adapters.

I found out (I haven't verified this myself) that these sensors are of US 280F range, so I'm assuming a gauge won't be an issue.........

Also, I bought the 3-pin connectors from Simtek UK (CON-323):  Direct Link

I need to put some extra wiring into the loom to accommodate the sensors, and I will post when that is done.

I had to drill and tap the housing above the oil filter since this was blanked off.  This was done by removing it from the engine, drilling and tapping it to M12 x 1.5mm (Not a standard M12 thread).  This was fully cleaned from debris before bolting back together.

I hope they work.......
