So here we are one week until our long awaited family trip out west in our GMC and she is falling apart!
First, I replaced the AC compressor for the third time but this time I installed the new S6 compressor that Applied sells. This compressor is s direct fit as Applied advertises and is only half the weight of the A6. Looks to be a nice unit. So I installed the new compressor but I wanted a pro to flush out the old oil, replace the drier and properly service with refrigerant. Found a great shop local to me and it turns out they are authorized dealer for these S6 compressor and is very familiar with them. Anway, they did a great job and was soon blasting cold air. Well first trip we took in the GMC, back in June, the AC lost all its refrigerant! Took it back the shop and he found one of my new hoses (replaced 4yrs ago) was not crimped properly and sprung a leak. In fact you could see the oil dripping out of the hose. Point here is new hose and failed a few years later, less then 6k Miles. So I had a new hose fabricated and reinstalled, this was yesterday.
It gets better....This morning I took the GMC back to the shop to have it serviced after the hose was replaced. As I left the driveway I had no brakes and the brake light came on.I pumped it up several times and immediately got full pedal back. WTF. Note, everything from the MC to the rear brakes replaced 3 years ago (~3.5K miles). Okay I have the brakes back and the shop is 3 miles from the house so I'm pressing on. On my way to the shop the engine starts to sputter under acceleration. If I floored it the engine would stall....NOW WHAT! I switched to AUX and the problem went away (I installed in tank fuel pumps this spring). Hmmm...sounds like the main fuel pump took a crap. Oh great.
So I press on to the shop, they serviced the AC and leak checked, all is good with the AC. Now, on my way home from the shop I noticed when I applied the brakes and just as I come to a stop I heard a low rumbling noise...holy crap...what the hell is that! I am now seeing my long awaited family trip to Yellowstone fading fast.
So I get her home and looking through the slots of the Eagle wheels I see the passenger side rotor is heavily scored! WTH! The brakes pads have less than 7k, how can they be so worn. I just inspected this spring and they looked fine. I think they are down to the rivets. I haven't taken the wheel off yet to inspect, I'll do that later. Could this be the reason I got the momentary loss of brake pedal?
Back to the fuel problem. After I discovered the rotor is scored I did some trouble shooting on the fuel system. I disconnected the line to the carb and placed it in a fuel can and found that with the main fuel tank pump on, the flow is half when compared to the AUX fuel pump. Since I lent out my fuel pressure gauge to a friend I can't check the pressure but it is obvious the flow is half of the Aux and the main pump is the problem. So looks like I have to drop the fuel tanks and of course the fuel tanks have about 40 gallons of fuel!
I'm really stressed that I have to drop the tanks, possible replace the MC and deal with the brake pads just one week until our trip. None are to difficult but I have very limited time to work through this problems.
Most frustrating for me is that all of the above problems are caused by parts I have replaced with "new". For me nothing is more frustrating then having to replace a part that was just replaced with a new or "rebuilt" one. In fact most of the problems I have had have been with the new parts. Water pump lasted two years, AC compressor two years, Ignition module three years, AC hose 4 years, possible I have a bad MC, replaced just 3 years ago and an electric fuel pump, one month. I guess there is nothing we can do about these Made in China crap parts but it sure has costed me money and more importantly my time!
And a note to our suppliers, the comments above about the parts are not directed to you in the least bit. I think I can speak for most of us when I say that we all appreciate the services that you provide and would be much more difficult maintaining our GMC with out your support!
Whew, I feel a little better after venting here. Thanks for listening to me.

Jon,
So sorry to hear about Murphy's visit. (You know about Murphy's Law: What can go wrong, will go wrong.) Numerous things as usual. You have already addressed this probably, but is it possible you have swollen front brake lines, the rubber ones, I mean. It could maybe explain the passenger brake wearing out from not releasing. Other possibility is that if the inner and outer pads are worn much differently, you might have to lube the caliper pins. Takes some special grease.
Very sorry to hear about that in-tank pump. No solution for that besides what you are going to have to do. You will be better at it anyway and it pumps enough for you to drain the tank at least. Still a sloppy, slightly dangerous job.
Of course, there will be more definitive advice here. One more push and a great vacation awaits!

Jon, I suspect you will make it. A common problem for the front lining wear is an old front brake hose collapsing and not returning fluid to the master cylinder and also holding that brake on. If you can get the hoses in time, I would replace the master cylinder at the same time--it is a very easy install. As far as the fuel issue, I think you can do your trip as is since one pump should be able to give you about 89% of the fuel you have on board (except if you are doing a lot of climbing)

Good advice from Bob D. Take a deep breath, concentrate on the brakes and use the Aux tank fuel pump if necessary.

I absolutely hate in-tank pumps. I have replaced too many of them on various vehicles and it is not a fun job. I have replaced so many GM Blazer/Jimmy pumps that I carry a spare in both my Blazer and in my wife's Jimmy. But I still have to drop the tank to get to them.
A while back before one of my Canadian trips to the Northwest Territories I got a extra external 60 PSI pump (Blazer needs 54 PSI minimum to run) and fashioned a couple of connections where I could slide underneath and replace the in-line filter with this spare electric fuel pump if the in-tank one failed. Using this I this way I could continue on my way. Even though there is a check valve built into the OEM in-tank pump, when I tested the temporary lash up external pump, it worked just fine.
All of that said, I can not comment on your pump installation because I have no idea what was installed. If it were me I would go ahead on vacation, get a spare external pump and carry it with me. If you are using a carb then a Carter P4070 would be a good choice. Then go on your trip using the already installed aux pump and forget using the main. If it quits, install the Carter just before the selector valve and power it off of that valve. It only draws about 1.5 to 2 amps.
On the brakes, I think you have one of 4 problems. I'm assuming it is a front that is grinding.
1. A brake pad disintegrated and you are running on the steel backing.
2. Your caliper pins are sticking and you wore out one pad.
3. You caliper is sticking.
4. A brake hose is bad to that wheel and the pad failed to retract.
Any one of these four should be a couple of hours to fix with locally purchased parts. Even if the rotor is scored, you can still just install new pads and let them wear in to the scored rotor. I have one scored rotor on my Colorado that I just installed new pads on. Rotor replacement is a real pain on that vehicle requiring spindle removal. I have been running like that for about 40,000 miles.
Good luck on your quest, and go ahead on your vacation.

These things happen and without the commitment that your being counted on to have the transportation ready, one would give it up.
Back in 1990, when we were going visit New York and all that historical places, I ended up purchasing another new refrigerator as he one year old unit went bad and I could not delay the trip. Blew 5 tires that were 4 years old so I had to purchase them, exhaust system came apart, so we had to have it welded twice, blew a hydraulic lifter, generator starter got stuck,a/c compressor froe up,
It was a tribal for me, but Grace di not say any negative thing to me and we made it back.
Oh, I picked up 3 speeding tickets.

Jim I didn't even have to see the signature line to know that was you. The speeding tickets clinched it.
