well if you are looking under the hood (facing the truck) it is just right of the distributor( so drivers rear of engine), BUT your not gonna see it unless you remove your upper intake off :rolleyes: , yeah i know it sucks, some guys have changed it without removing it, BUT man i don`t like to swear that much :crackup: (doing stuff blind), you`ll need some really small internal snap ring pliers, other than that, taking the upper off its not such bad a job (carefull of the injector harness). I highly recommend you replace or really check the vacumm hose that attaches to it (the regulator) when your in there!!!

 

:crackup: HAVE FUN, any questions letme know i`ve done more stuff to my 454 than i care to admitt!!

Just hoping you can answer my question too. I've got a 2000 454 that is loosing fuel pressure when shut off. Almost as soon as the pump quits the pressure starts to drop, making for hard starting, and for the first block or so the truck just will not hardly pull itself off idle. So my question is does the pressure regulator have a check valve in it or is it at the tank?

 

thank you for any help or suggestions

pretty confident the check valve is in the tank with the pump assy, cause you have to depressure at the bleed to change the F.F. which is before the reg. it is weird though that your truck doesn`t come of idle for the first little bit, have you driven with your pressure tester on it to see what the pressure is when it acts up? the two problems kinda seem un-related.

 

i`ve had many problems with the injectors leaking down, hard starting warm, and when it did start it smoked abit because it was so rich, but it cleared as soon as it started up. i would clean your throttle body, and the mass airflow sensor with an aerosol cleaner and alow to air dry, don`t use compressed air on sensor, it also could be a problem with the throttle position sensor, i`m not sure of the specs but a shop can check its readings with a good scanner and see if its reading right range, check for leaks too, rare but could be reason for probs,

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
