A bit more progress on the GTO fuel system. I made a few small brackets to hold the pressure regulator and the flex fuel sensor, and connected all the lines from the tank.
To test things out I hardwired each of two pumps (one at a time) to check for leaks and make sure both pumps are working.
Next up is to redo the vacuum/boost connections in the engine bay and wire up the second fuel pump switch. I also need to install a real AOS and get that plumbed correctly.
Today is a good day for tea and a fire.
Why read fiction when you have stories like this!
On a more serious note, read something challenging tonight. Pick something that is just a little beyond what you can read quickly. If you have to flip back pages a few times, and even stop and dig into something to get through it, you will be all the wiser for it. The TV will still be there tomorrow, but the time left you have to learn will not.

Time to work on the fuel system up front, which means fittings. I dug into some boxes to see what I had sitting around from other projects…. and of course that means whatever I find will be all of the fittings I don’t need.
I did take the time to sort all of them and bag them so I can find them later when I realize I do have that one fitting.
A tad more work on the GTO:
New billet fuel hat and pumps installed, and feed line attached to the bottom of the tank. New fuel line to the front is next, then regulator, filter, and flex-fuel sensor.
Time to get the fuel tank out… It does make the removal of the top hat easier since the tank is sitting on the ground ( in contrast to being under the back seat in a cramped car).
When this car was sold (and built) in Australia, I have heard that the fuel tank was on the bottom of the car (like most cars), but for some reason to meet US standards they had to move it into the trunk. That steel protective cage is surprisingly heavy and stout.
It is amazing how dirty that filter sock is on that pump… this is probably 10-15k miles on that filter, with a little E85 but lots of Methylcyclopentadienyl manganese tricarbonyl.
I am switching to a return style system on reassembly. The stock system is terrible in that the regulator is built into the bucket assembly. It might not be obvious, but the output of the fuel pump is that black hose you see sticking out of the bucket assembly. When you install the bucket that hose connects to an internal fitting that goes to the bottom of the tank, then to a line that goes up front.
I’ll use the factory feed line as a return line, and run a new feed line.
I’m looking forward to installing my first ID750 fuel filter [http://injectordynamics.com/id-f750-fuel-filter/]. It will be the best looking thing in my engine bay. 🙂
With the turbos done, it is time to do some work on the hacked-together fuel system on the GTO. First task is the pull out the fuel tank, which is sitting in the trunk (really, the fuel tank is in the trunk on the GTOs. Crazy Australians!). To pull the tank, first empty it!
I currently have a very hacked up fuel bucket with a Walboro 450 pump in it. A while back one of the guys on the GTO forum made a nice machine aluminum billet fuel hat and holder with two pumps. I’ll use that in the tank to feed into a small surge tank (Radium), then have a couple of 450s in the surge tank to feed the engine. That should give me enough capacity for running E85.
It lives again, with new turbo too.
We rented out Smithsonian National Portrait Gallery for a work dinner. Cool place!
Hmm. This looks familiar. PDX-DCA way too early in the morning.
