    Primary tank good, auxiliary tank spits and sputters

    It may be worth noting that almost all the in-tank fuel pumps I've purchased come with the wrong hose that melts and fails in a few months. Get hose that's rated for submersion in fuel. SAE J30R10 http://www.gmsquarebody.com/forum/showthread.php?t=15026

    Connecting with a laptop with Tuner Pro RT and DIY cable.

    Tunerpro and winaldl will run on 7. Not sure about 8 or 10. I was pointing out that a laptop isn't a show stopper right now. Vmware works better than the mickeysoft virtualisation software and it runs on Linux and windows. You can install software from a USB stick. Sent from my SM-P605V using...

    Wrong fuel gauge?

    All three gas gauges were not working and both diesel gauges were. End of story. GM used magnetic gauges from 1965 till they slowly rolled out the stepper motor gauges driven by the ECM in the 1990s. The base of the gauge needle has a small magnet that "floats" in a magnetic field created...

    Connecting with a laptop with Tuner Pro RT and DIY cable.

    With the demise of Windows XP there are more than a few Dell Series 520,30 620,30 & 820,30 and similar model families showing up on Evilbay. New Lithium battery packs for that series of laptops are cheap and available. XP is the last OS that has a reliable NT Virtual DOS Machine. It should be...

    Tail light issues?

    The Hazards work just fine, the running lamps light up fine, and the backup lamps are OK. The wiring to the back is probably OK. If you replace the fuse again and just run the RH turns does it blow out? If no... does the fuse blow with just the LH turns? No blow means you have a problem in...

    Tail light issues?

    There are TWO flashers... one for Turn and one for Hazard. In 1985 the Turn Flasher power (Circuit 36) and Backup lamp power (Circuit 75) are from the same 10A ATC fuse. I guarantee it's blown. It's marked (TURN B/U) in the fuse panel. The Hazards and Stop lamps are on a different 15A ATC...

    If the 1989-2016 GM W-Body lateral links are the same length then you can buy some pretty beefy adjustable rods ready made with eyes on both ends. But why buy the expensive hot rod parts... For this application you don't need beefy parts like the ZZ-Performance or UMI tubular lateral arms...

    Junction block issue?

    There are three studs on some Delco starters but only two of the three are used on the CK trucks after 1974 or 1975. The 3/8" BAT stud is obviously the battery and one or two fusible links depending on the year. The other two studs are machine screw threads. The #8 stud is for the crank wire...

    Hose Clamps Hose Clamps It's fairly easy to use the wrong clamp for the job. Worm clamps are a good example. Just because you can spin a 1/2" ID worm gear clamp down to squeeze 3/8" OD hose doesn't mean it's working as well as the clamp designed for that job. -Worm Gear Clamps I avoid...

    Fluid and vapor hoses. What should I use? How should I clamp them. Many aftermarket and even OEM parts, like fuel pumps, transmission coolers, and inline filters, ship with the wrong hoses causing more than a little trouble when they fail prematurely on parts like in-tank fuel pumps that are...

    Compnine has some of these trucks in their database. It's $9 or something like that. You can feed your VIN to the page to see if they have it before you spend $ on the whole deal. http://www.compnine.com

    Tack Filter

    It bleeds off unwanted electrical noise like high voltage spikes. Aftermarket tachs typically have the filter built into the tach itself GM chose not to.

    As long as your 1991 is an RV chassis. The harmonica plug will line up. After 1985 the wiper and dimmmer will mate up. Not sure about 1984. Do the Jeep YJ steering shaft upgrade and you won't need to worry about the steering shaft. If it's from a GMT400 CK chassis I'm not sure. Sent from my...
