3 weeka ago, (on tbe burb), i Pulled a 3hr vacuum on my system, did a 1 hour leakdown test... seemed ok...
Last year i did a total overhaul on the system, but it all leaked from the compressor.....?
This time, i added a can of that mechanic in a can stop leak to the system, as well as however many cans until i saw an agreeable high and low side pressures i liked.
Drove the burb 4 hours to SC last saturday , ac pumping icey the whole time, and cruising around in the sweltering heat..... she stayed cold inside the entire time (front and rear ac)
Drove her back yesterday, again no issues.
*knock on wood* that 30 year old truck made it further than some of the shitbox broke down trucks i passed on the highway...
Typically ran her 75 mph most of the time.... no issues.....
As for the c10, its been sitting a couple weeks, i kept getting a 30 something AFR (lean), and it would threaten to spit thru the holley efi under any load, overheat, etc etc. I told myself this wouldnt be a rushed project , and it wont be. So i work on it in my time.
Today, (this am) i checked the fuel pressure, had the wife cycle the key twice... both times, 20 psi... yucky.
the holley needs to see 60 psi to function.
So, i guess i get the jackass award for not just buying a fresh new Acdelco ep381 fuel pump, and installing it with the new tank and sending unit when it was on the lift at my buddies house.... meh whatevs. ..
Tank got pulled today, new pump ordered.
EZ. Left myself enough line slack that dropping it was no problem, even with 14 gallons of 93 hehe
Ok.
So moving on , i recently got an automatic column from a 70 something c20, so i pulled the old zip tied, jerry rigged 3 on the tree column and swapped in the auto column today, also removed the old clutch stuff as well.
All that i need to do is button up electrical, put the dash back together, and it'll look decent.
Only complaint is the hole in the floor where the clutch rod used to be (directly below the column)
Is there a cap i can put there to cover the hole?or do i now have extra vented AC?
Doesnt really matter. Its not a show truck, its just a means to disappoint the local LS boys.
(Joke) some of them are my buds.
