  1. Once the refrigerant is in a gaseous state the only way it can go back to a liquid is be compressed and sent through the condenser. A properly filled A/C system will not cause slugging. Over filled or filling the system with an inverted can will cause slugging. Insulating the piping after the orifice tube and before the evaporator is no problem. After the evaporator some auto manufacturer choose to insulate the accumulator. GM has done it with this products like this. https://www.ebay.com/p/A-C-Accumulator-Insulator-ACDelco-GM-Original-Equipment-15-10614/79416292?iid=282964073381&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D52475%26meid%3D84e53c92765446a885aca61308b093e9%26pid%3D100005%26rk%3D6%26rkt%3D12%26sd%3D161767073957%26itm%3D282964073381&_trksid=p2047675.c100005.m1851 Ford did it with a spray on insulation but it caused the accumulator made of steel to rust out, there was no way for the condensation to evaporate. Now they are made of aluminum. Mercedes covered the A/C lines in the 80's and 90's.
  2. Heat always moves to cold, that's physics. So any part of the low pressure side of the A/C system from the expansion valve to the evaporator and accumulator is colder than their surroundings and will absorb the heat. This is extra heat that has to be removed from the system through the condenser. These 16 year old condensers aren't as efficient as when new so the system could use that added help of insulating the low pressure pipes, hoses and accumulator.

    D80 ring and pinion

    I'd take the cover off, spray it down with brake clean and blow it out, then refill. Cheap insurance, no need to have any thing going through the bearings let alone the ring and pinon.
  4. Here are the wire diagrams for the transmission
  5. Well, I checked the vacuum system with a vacuum gauge and found that the vacuum was coming up very slowly and the vents would start to change at 6 in Hg and be fully opened at 8 in Hg. This took at least 30 seconds from start up and maximum vacuum was 10 in Hg. I disconnected the vacuum hose that comes from the vacuum pump at the fitting on the fire wall, installed the vacuum gauge and started the engine. The vacuum again rose slowly but as I moved the hose around a bit the vacuum would jumped up to 28 in Hg. So that tells me that the vacuum pump is working and there is a problem with the plumbing. Inspected the plastic hose and fitting to the pump and found the rubber the fitting is made from deteriorated. The fitting is now replaced with a 3" peace of vacuum hose. The vacuum now climbs to 28 in Hg in less than 5 seconds on start up. If you find one fitting that looks like this you will want to replace all the others because after 16 + years you know they'll be in bad shape too.

    ABS or Divider

    Had that happen on a work van with rear drum brakes. It turned out to be a sticking brake wheel cylinder on the right rear.
  7. Here's how to make a relay mod if one doesn't come with the new pump.

    Algae in Fuel

    @CTcummins24V I run my edge on level 2 and @dripley is right about the boost. If it's towing or not the best boost I see is 30psi, that's what I set the boost controller at and I don't think my HX turbo would produce much more than that. I normally drive 65-70 and tow at 60-65 mph, the boost is 0-5 psi when cruising.

    Algae in Fuel

    Right, It's a 24 micron stainless steel mesh fuel strainer used pre-pump. It is not a fuel filter. I think I'll get one for my Fuel Boss system.

    Algae in Fuel

    Do you have an electrical back up fuel pump with that Fuel Boss. If so you could add a fuel line to the system, energize the pump and have it fill 5 gallon fuel cans or stick a hose in to the tank filler neck and siphon it out.

    Well the Order is in

    That's the 4th of July. You think some Auto Workers Union wonk is going to be there for less than triple time?
  12. You may need to make your own set up. It would be easy to do with a fuel line T-fitting with an adjustable hobbs pressure switch like the one that is supplied with the Fuel Boss lift pump. This set up is used to turn on and off the back up electric fuel pump and can be adjusted to any pressure you want.. In stall an LED light like the one below in place of the fuel pump. By the way, 10PSI is to low. You want fuel to run through the pump and back to the tank to keep the pump cool. The return line valve doesn't open until 14PSI so you will want to set it for 13PSI..
