I finally found some time to work on the truck again. I re-wired the SPAL cooling fans with SPAL relay kits. I had previously used some relays I had on hand and some bulk wire and just wasn't thrilled with how it turned out. I also neatened up the wire a bit by installing some black convoluted tubing. Now all of the FAST XFI wiring blends in a bit better.
The A/C hoses are installed. I have a little more wiring to do and then a recharge.
I have had a vacuum leak between the sheet metal upper 1/2 and the cast aluminum lower half of the intake. All along I had doubts about how well it would seal with just 4 small bolts widely spaced holding the 2 pieces together. Intially it was decided to bolt them together in case mods were needed inside the plenum. I decided to pull the intake and weld the 1/2's together. I figure if it needs to come back apart, I have carbide die grinder bits and a welder.
The big question was if i would be able to do this. I have very little TIG experience and no training. This was the first time welding a combo of plate and cast aluminum. I think I did OK- not to pretty, but funtional. It actually came out better than I anticipated. I figured if it was really bad looking it would not be visible anyway.
No more vacuum leak !
