    Ds4 fitting for fuel pressure gauge

    Ok, I see now. Huge difference in flow from one brand to the next. My world is the DB2- so just a street T with the side tap in 1/8” is easy. The best fittings I have seen for the ds4 tapping the fuel gauge is found doing search on places like Summit racing- I couldn’t get link to copy right...

    TPS question on TH400 to 6L80 transmission swap with a 6.2 diesel?

    https://real4wd.com/product/sensor-engine-speed/ Thats the 2 wire sensor that uses the ds4 crankshaft reluctor wheel with the newer timing cover where the crankshaft position sensor is normally on the ds4 engines

    Ds4 fitting for fuel pressure gauge

    The T fitting for the fuel pressure gauge- you don’t want any rubber line after that T. That becomes a frequent failure point and you THINK everything is ok, however a restriction in the line occurs there. There was a “tool” at the dealership that was part of a fuel pressure test kit that...

    TPS question on TH400 to 6L80 transmission swap with a 6.2 diesel?

    As mentioned above- some db2 have tps and some don’t. Idk of a tps that mounts separately to one that wasn’t designed to have it. You might end up needing to swap to a civilian db2 to get it. On the engine rpm- there is a couple of options. 6.5 that have the ds4 ip (injection pump) use a...

    My son's 1968 Chevy

    Sounds good man. Yes- the head cracking prone 230 & much improved 250 came stock with the manual, powerglide 2 speed or the TH400 is same as far as bellhousing and such. Torque converter- idk about that. It will bolt up, but idk if the stall speed is the appropriate one to use. Make sure...

    What did you do with your GMT400 today...or yesterday....

    When you push in the clutch- that force against the clutch fingers is forcing against the crankshaft. Imagine the transmission, clutch and flywheel all attached but no engine. The flywheel is just going to move forward from the force and the clutch won’t release. All that forward force...

    Engine RPMs revving while driving

    I haven’t had him call me in a couple years. (844)416-2342 is his shop number. Give a call Monday & ask. Remember stock is 5/16” and FTB is 3/8”.

    Ds4 fitting for fuel pressure gauge

    I can’t remember. I know guys on HML bought them. Most folks that diy the labor just gets one from amazon and saves a few bucks.

    My son's 1968 Chevy

    I always disassembled them for cleaning & inspection. They hen reassemble andI putting them in a small bowl of oil and used a pushrod to manually pump them up and bleed out the air. I know a ton of people who soak them for a couple days before install- so I do that also

    My son's 1968 Chevy

    We always did it with a cut out rocker cover- rag over top of it. Start engine and idle. Go till ticking stops and 180° to 225° depending if you wanted more power =180° or quieter engine= closer to 225°.

    Possible Engine Build for my 93 Truck

    No matter which oil pump you get- you can use the ol die grinder and burrs or stones and make some very nice improvements on the oil flow through it. Search what was taught by Smokey Yunick. That guy lead the world in things like this. Copy how he showed to do it best you can and even your...

    Possible Engine Build for my 93 Truck

    I don’t remember if 6.5 hv can drop in or not based on if the oil pan is different for that year truck. But here is a post I made on pumps before:

    How do you all get 6.2s to 300K miles

    The design on the two chambers & air filter mount is creative and looks neat. But I would clean it up & sell it. Punch a hole in the fender for a snorkle that hits a filter in an enclosed box on the fender well. Then to the turbo- then add an intercooler and from there to the intake manifold...

    How do you all get 6.2s to 300K miles

    Advantage of being advanced- better power. Advantage of being retarded- better mpg. Db2 timing adjustment- you can’t get it accurate enough to improve either of the above by ear- you need one of the specialty tools. If you go a hair too far in either direction you loose the small gain you could...

    Possible Engine Build for my 93 Truck

    I prefer brass for the larger plugs. They are the ones that fail first and the brass ones can’t rust like steel.

    How do you all get 6.2s to 300K miles

    On the temperature control, I would say try a new AC Delco or Robert Shaw 180°thermostat. Keep the old one. I’m no help on the rear window.
