I like to repurpose OEM parts as part of my builds. I am not sure how I ran across this part, but it is from a 2008 Ford F250 with the PowerStroke engine.

https://j.hmjimg.com/2023/03/18/GTOV3-812.md.jpg

This is what Ford uses for the exhaust pressure sensor, and I figured I can use it for the same purpose. In this picture, the tube has been cut and a sleeve installed over the cut. The sleeve ends where the green tape is and where my finger is pointing.

https://j.hmjimg.com/2023/03/18/GTOV3-813.md.jpg

This is the sensor part number. From what I have been able to gather, it is a 0-54psi sensor.

https://j.hmjimg.com/2023/03/18/GTOV3-814.md.jpg

The tube is stainless and 5/16" diameter and it uses 37 degree flares with tube sleeves and nuts at both ends. That size tubing translates to an -AN5, which is not super common. Luckily, I had this 90 degree NPT to -AN5 adapter that I was using on the old tank for the return line. The NPT side has been cut off and Vic turned it down in the lathe to make a -AN5 male weld fitting.

Here you can see where the fitting is going to go. Yes, the first hole was way off...

https://j.hmjimg.com/2023/03/18/GTOV3-815.md.jpg

The whole assembly is bolted to one of the holes on the back of the heads...

https://j.hmjimg.com/2023/03/18/GTOV3-816.md.jpg

and the tube extends down to the crossover pipe...

https://j.hmjimg.com/2023/03/18/GTOV3-817.md.jpg

Once the tube was the right length and clocked correctly, the sleeve was welded to the tube.

I arrived at Vic's this morning and found that he had already stuck the stock dipstick into the lathe and got rid of the ugly yellow dipstick handle.

https://j.hmjimg.com/2023/03/18/GTOV3-818.md.jpg

He also took a piece of Delrin that he had on hand and made a new new dipstick handle, which is much more appealing.

https://j.hmjimg.com/2023/03/18/GTOV3-819.md.jpg

Once the parts were ready, they were cleaned and mated together with some JB Weld.

https://j.hmjimg.com/2023/03/18/GTOV3-820.md.jpg

Much better...

https://j.hmjimg.com/2023/03/18/GTOV3-821.md.jpg

Here it is, in case you didn't notice it.

https://j.hmjimg.com/2023/03/18/GTOV3-822.md.jpg

I also mounted the AC condenser in its location and removed the protective cardboard from the radiator.

https://j.hmjimg.com/2023/03/18/GTOV3-823.md.jpg

I will have the AC and the heater plumbing sorted pretty soon.

Andrew

Work looking good. Making me want to ditch the ugly yellow dip stick with machined goodness.

I'm a cheapskate, mine has some black plasti-dip, doesn't appear I could get the stuff off if I wanted to lol.

I decided that I wanted to rotate the Holley Lo-Ram front to back, which will put the MAP sensors in the front.

https://j.hmjimg.com/2023/03/21/GTOV3-824.md.jpg

The main purpose for rotating the manifold is to clean up the area behind the intake and have the ability to use the stock oil pressure sensor in the stock location. I should have done this at the beginning...

https://j.hmjimg.com/2023/03/21/GTOV3-829.md.jpg

Rotating the manifold involved a bunch of changes. One of them being the plate that holds the boost solenoids. It still fits, but it had to be cut to clear the Bosch TMAP sensor.

https://j.hmjimg.com/2023/03/21/GTOV3-825.md.jpg

I also picked up some AC hose ends locally. The top hose that goes to the condenser is from the compressor.

https://j.hmjimg.com/2023/03/21/GTOV3-826.md.jpg

The lower hose goes to the dryer. I have a new dryer on the way along with a AC pressure sensor, which will replace the binary switch. The AC compressor will be controlled by the Dominator ECU and the HardWire PDM.

https://j.hmjimg.com/2023/03/21/GTOV3-827.md.jpg

I got a 45 degree fitting for the #10 hose that goes from the evaporator to the front port on the compressor. The rear port on the compressor is a #8, and goes to the top of the condenser.

https://j.hmjimg.com/2023/03/21/GTOV3-828.md.jpg

I also took out the dash insert.

https://j.hmjimg.com/2023/03/21/GTOV3-830.md.jpg

With the ash insert out, I will be able to get to all of the wiring and ducting behind the dash, without actually having to pull the dash out. The 3 gauges that are front and center will be the Holley CAN RPM and Speedo, as well as a small fuel level gauge.

The holes on the right will be filled in. The 6.86" Holley Pro-dash will go where the three larger gauges used to be and below that will be two AC vents.

Andrew

This is a small update with, hopefully, useful information.

Since the Holley EFI will be controlling the AC compressor, I wanted to use an AC pressure sensor. This is a little adapter that VA sells just for that purpose. Also pictured is a new VA dryer, where the fitting goes.

https://j.hmjimg.com/2023/03/23/GTOV3-831.md.jpg

This is the AC pressure sensor that I am using. The main reason that I picked it is because I have the output configuration for it.

https://j.hmjimg.com/2023/03/23/GTOV3-832.md.jpg

This is the new dryer, installed in its location on the radiator core support.

https://j.hmjimg.com/2023/03/23/GTOV3-837.md.jpg

A lot of people ask me which oil pressure sensor I like to use on Gen 4 engines with Holley EFI. This is the one, and the connector on the Holley EFI harness has the correct connector. It is a 135psi sensor.

https://j.hmjimg.com/2023/03/23/GTOV3-832a.md.jpg

This sensor looks similar, but it has a 12mm thread on it, instead of the 16mm thread on the sensor shown above. I had this end cap for the Holley fuel rail, so I had an idea...

https://j.hmjimg.com/2023/03/23/GTOV3-833.md.jpg

I told my idea to Vic and a little while later my idea was made reality.

https://j.hmjimg.com/2023/03/23/GTOV3-834.md.jpg

Vic drilled and tapped the cap for the 12mm thread and a groove for the o-ring to seat against.

https://j.hmjimg.com/2023/03/23/GTOV3-835.md.jpg

I installed it in the rear of the driver's side fuel rail. So I have a fuel pressure and temperature sensor after the fuel filter and this sensor in the rail, mostly because I can.

https://j.hmjimg.com/2023/03/23/GTOV3-836.md.jpg

Vic is also making progress on modifying the dash insert to use with the Holley Pro-Dash.

https://j.hmjimg.com/2023/03/23/GTOV3-838.md.jpg

The small hole to the right of the steering column will also get filled.

https://j.hmjimg.com/2023/03/23/GTOV3-839.md.jpg

Killing it :bow:

Nice ideas for those up grades, Boy that Vic is a handy guy to have around!
Vic you ever think of moving to Massachusetts? lol

Since I decided to rotate the Holley Lo-Ram base front to back, I needed to add a fitting for the catch can. Instead of using the typical NPT to AN adapter, I used this straight thread ORB adapter.

https://j.hmjimg.com/2023/03/24/GTOV3-840.md.jpg

All that is needed is a little counter-sink for the o-ring to seal against. Sorted...

https://j.hmjimg.com/2023/03/24/GTOV3-841.md.jpg

I needed a pass through for some wires to come through the firewall, low on the passenger side. This pass through is for wiring the heater control valve, fan speed signal, AC pressure sensor, EGT probe, and the dome pressure sensor.

I enlarged an existing hole to 1" using a step drill and...

https://j.hmjimg.com/2023/03/24/GTOV3-842.md.jpg

used a TE Connectivity 90 degree heat shrink boot passthrough.

https://j.hmjimg.com/2023/03/24/GTOV3-843.md.jpg

This is the 4 port, electronic heater control valve that I am using. It is sold by Thermotion. This will allow the coolant to flow through the heater core circuit when the valve is closed to shut the coolant flow through the heater core, when the AC is being used.

https://j.hmjimg.com/2023/03/24/GTOV3-844.md.jpg

Vic also finished filling the holes in the dash. He then fixtures the dash in the mill to make the opening for the Holley 6.86" Pro-Dash.

https://j.hmjimg.com/2023/03/24/GTOV3-845.md.jpg

Below the dash will be two of these VA dash vents:

Yesterday Vic finished the opening for the Holley ProDash.

The Vintage Air vents will be here tomorrow, courtesy of Summit Racing.
