Today I TIG welded the O2 sideband sensor bung on the right collector, and finished cleaning up the pipes. Now all is left to do on the pipes are to ceramic coat them flat black, but that will be done later.
Here is the sensor installed. I have to run and fastened the wire now, running it in front of the footbox, and through the factory firewall hole for the wires.
PS, I have no idea why the weld looks so bad in this picture... it is actually a nice weld, but I did file it a bit using a round file, to knock some corners down. Nevertheless, that picture looks bad, but the weld is good
Last night I pressurized the fuel system to see if it would hold 45 psi (since the gauges are installed). It does hold that value, but it takes a bit of time (15 seconds to fully build the pressure.) I hope that will be ok for engine starting and such in the future. So far, one found one leak. It is leaking from an AN fitting on the return side of the fuel rail, which connects the fuel rail to the regulator. I have to figure out if it is the swivel part that is leaking or just not tight enough, but it is very hard to put any wrench or anything to work on it. I will have to pull the fuel rail out
I think the fuel is coming out of the the collar, right under the blue portion of the fitting. I think that is the swivel portion.
I will focus now on the throttle system as it is the last thing in the way before starting the engine...
