Anybody have any guidance?

On my 305 dualjet with return, I had a carter pump and it lasted about 1-2 years

Finally gave out a few weeks ago

I ordered a Delphi and it was dead out of the box, wouldn't hold pressure unless I capped off the return line

Got a replacement Delphi shipped by the vendor

The replacement worked for about 30 minutes and then died, luckily I had some vice grips and was able to make it home.

The replacement won't hold pressure unless the return is capped also

It's crazy that you can't find a good fuel pump anymore

I need to cover the dashboard on my 80 C-10, I see some that are TPE type instead of the ABS one. Anyone used one of these?

I just picked up a 14 bolt ff rear axle for my '76 c20. The one I got looks just like the one I already have but the new one to me has lock washers on the axle bolts. Did chevy ever do that or was it just some prior owner doings would you say? My '76 does not have lock washers on the axle bolts.

76-85 Vehicles exempt from mah-smog laws!!

I haven't read the full details, I'm sure some smarmy pol stuck some crap conditions, but hey, it's a start!

Now I can cut that CAT off my girl, Cherry Bomb, and install some headers!

Hello all,

It's been a while since I posted on here, and honestly, it's been a while since I've messed with the ol' square.  We had some family excitement and travelling and bought a new house/moved over the past year and it's finally settling down.  TLDR section at bottom!

While I was moving, I used my 1985 C20 with 350/350 to take loads of tools and pool parts and trash to the places they needed to go.  She ran wonderfully and pulled quite a few big loads flawlessly. 

The last trip it made was to my mom's place, where we stored some things and I'm about ready to go grab it and bring it to the new house. 

My next little project with the square will be getting the AC system to work.  The blower blows and all the switches work.  The heater works like a champ.  The compressor turns, but it's noisy and the bearing may be on it's way out.  I pulled the belt off there, and have been running it without for a year or so. 

My initial thought was, 'Hey, I'll slap a new bearing in there, slap some R134 nozzels on there, vaccum, dry and charge it all up and cruise with some AC.

Then I started digging and watching youtube, reading forums etc.  So there are some folks that do/say to do exactly as I say and seem to be ok.

But then, there are the folks that change a few things out.

Then, there are the folks that change absolutley everything out. 

Now, I'm kinda cheap, but I also don't like doing the same thing over and over because I screwed it up to begin with. 

So what do I do? 

Currently, my shopping cart online is like $70 with a dryer, hoses, orifice tube, clutch bearing, and o-rings.  I will have to add the conversion to 134 kit and cans of r134 to that if I keep it simple. 

Do I NEED  a new Condenser?
Do I NEED a new compressor?
Do I NEED a new evaporator?

Or can I flush and pray??

Let how deep do I go?  (it's a field find.  sat for 30 years.  not gonna be a show truck.  just want to drive and enjoy and not sweat)

TLDR:  AC doesn't work and I need to know if I can cheap out and just switch some hoses and drier, or if I need to change all parts and pieces?


Thank you all for the info and opinions!
