Today we pretty much have what would be considered a wild card day. Sometimes things work out this way where one finds themselves bouncing around from one project to another, doing a little here and a little there, not really focusing on any one thing. The first episode starts with the Scion's AC not working the previous day. Thinking this would be a routine check to see if the system may have just went down normally, as is the case with old systems with bad seals and all. After adding some stop leak, as a normal measure, then starting to add some refrigerant, as the system started flowing the cool stuff through, I found exactly what was happening. One of the metal lines had a pinhole in it, which became known when the coolant started flowing through that side of the system. This pretty much put this little task to a standstill. I couldn't even remove the metal line as there was a plastic fitting covering the junction which requires a special tool specific to Toyota systems. Step one will be just getting the metal line off. Then, I have to actually source this thing, whether from the junkyard or online. With that at a standstill, I moved on to Truckstang, correcting the issue I had with the oil pressure gauge and sending unit. This involved assembling some plumbing fittings in order to bring the sending unit out from the block and the tight quarters that prevented me from being able to use the piece in the same way as the old unit. With teflon tape and tools, I assembled the ensemble and secured the piece in place where the old sending unit was located. With the new setup done, I just had to clip off the wire after the inline resistor and add a crimp terminal to clamp to the new sending unit terminal. The whole job was quick and easy to do. With the little bit of work done on the Truckstang out of the way, I moved on to the Rustang, picking back up with a little bit of fitting regarding the lawn mower carb project. This time, I wanted to fit the gallon fuel can and metal lines that would connect to the fuel pump and carburetor. I ended up having to remove the horn bracket assembly since it was mounted on the driver's side. I remounted the unit on the passenger side and added extra wire to connect the horn back to its relay and ground wires. With the horn cleared from the area, I fit the fuel can in place and bend a section of metal line so I can test fit the setup I'm trying to build. I will have to drill a couple holes in the fuel can and probably use some JB weld or something on the order of that to seal the tubes in the top of the fuel can. I still have to figure out how to secure the can in place. Also, I'll need to add some lengths of rubber hose to connect the input side to the fuel pump to the metal line going to the fuel can. I'll be a pretty simple and bootleg kind of arrangement, especially since this is temporary and just for the sake of testing MPG more so than actually doing a whole new setup. Once I do my tuning and testing to get the kind of readings I hope to get with this setup, I'll hook everything back up like normal, and do some more testing with the idea of setting up what could be a viable long term setup for this vehicle, or any vehicle for that matter. Being able to arrange a setup that can hold up to the rigors of automotive operation while still delivering the performance I hope to achieve would put us in a position to further show how this is a viable means of operating an engine in an economical manner, above and beyond the old school 1 and 2 bbl carburetors that used to be used on larger engines in the past.
