    LMC truck gas tanks, senders and brackets

    My response from another thread: I Also have an 86 K20! I too found it challenging to mount the brackets / tank (new brackets, new tank… both from LMC). I used a large piece of cardboard and some scrap wood under the tank (cardboard for scratching, wood to prevent damage of threaded rod...

    Stalling Issue

    I’m not sure what HB means… Fast99 wrote “…It may have a HB problem due to pulsation but shouldn't cause stalling. Later on, when it runs right flush out the old PS fluid.”

    I am not qualified to answer your question… tho I am curious, could a fuel filter and/or fuel sending unit play into this -to some degree- in anyway?

    86 K20 Front Leaf Springs

    I didn’t this realize this!! Before I found my k20, I passed up on several low mile good condition CUCV’s out of fear / ignorance, that I would have to do some major swaps to not burn anything up.

    86 K20 Front Leaf Springs

    They are flat and those rear springs are beefier than mine. I suppose a cucv called for that tho? Different topic: How or will u or can u even address the speed limit rating of the cucv (65 or 75 is it)?

    86 K20 Front Leaf Springs

    After I wrote this I realized I hadn’t been that clear. When I think of leaf springs, I typically think of rear leaf springs having a “big smile.” My fronts tho, have a slight frown.

    86 K20 Front Leaf Springs

    Just replaced shocks and steering stabilizer. Observed, after I lowered the truck back to the ground, that the front leaf springs on my 86 k20 4x4 (former plow truck) are arched up slightly. Is this proper or are they simply shot? Thank U :)

    86 K20 Curb drop = temporary Clutch No Engage

    86 K20 350M (L,1,2,3,R) 4x4 Just installed new clutch master & slave cylinders. I bled the system & am fairly certain I got all the air out. NOTE -I did NOT bench bleed the master. I first went about bleeding the system the old fashioned way… this obviously took a while. So long, in fact...
