The DS4-831-XXXX Diesel injection pump is a rotary Distributor-type Solenoid-activated 4 pumping-plunger 8 cylinder 0.31" plunger-diameter model - the four remaining digits denote Stanadyne final calibration specs - it is a constant-beginning variable-ending pump design with...
Barometric pressure is Atmospheric pressure, measured in pounds per square inch actual, or psia, 0 - 15psia (rounded up from 14.696psia mean) - 14.696psia BP, or one atmosphere, = 1 BAR
Vacuum is any reduction in atmospheric pressure, measured in inches on the mercury column, or "HG, where...
The FSM's are fraught with unpardonable errors - certainly not the least of which concerns the 4L80E TCC solenoid dc resistance value: indicated value is 20-40ohms - real-life works-fine-lasts-a-long-time value = 10-15ohms - read and heed - also, now would be prime time to correct your...
White vapors, usually referred to as 'white smoke' by the uninformed, are completely normal in cool\cold weather when starting an infernal-combustion engine, be it gasoline-fueled or Diesel-fueled:
a - when a running engine is turned off, as the engine\exhaust system cools, raw atmosphere...
Remembering lessons learned when lighting the ole BBQ pit\grill:
- add too much igniter fluid on barely lit coals and you get white vapors = too much fuel lowers temperature below combustion level, fuel never reaches ignition temperature but is above vapor point temperature
- add too much...
Good news - Ford has just approved the Provent CCV system for dealer-install on their Diesel pickups, which means it has been certified by EPA
The Provent system is a crankcase ventilation filter that removes most of the oil from blowby gasses, allowing very dry gasses into the intake system...

Have been helping the neighbor with his '83 6.2 Burb - it's still a 23mpg 2500hd tow monster, but needed gp's and injectors and timing chainset at 289kmi - disassembly sorta seems like it may have been a '93 Mr Goodwrench crate engine, with the '93 DB2
The CDR system from '83 is clunky and...
In this thread I will detail the cleanup, teardown, disassembly, and rebuild of a '96 47RE to 48RE specs, using upgraded 48RE mechanicals - the designated victim is on it's way, even as we type: a '96 47RE that broke at 90kmi behind a hi-output 12v Cummins CTD built for pulling - it is the 4wd...
Problem being - the long Dodge fuel tank is mounted longitudinally in the chassis, with the fuel tank module mounted about halfway center - this is good for cornering, but when accelerating or decelerating at low fuel levels, the fuel will slosh to either end of the tank, uncovering the fuel...
Got a Kubota 5600 HST 3cyl Diesel lawnmower - engine and chassis is too heavy for the steering, so wears the pinion gear badly - got a 80 Datsun manual steering box, gonna put that in there with a arc wrench, bet that sucker will steer from now on - plus, got the kit to overhaul the engine, as...

Here's the 6-range 8-class torque-input Rear-wheel drive Full Electronic control six speed transmission - has a separate TCM to handle the shifting chores -...
In this thread, I will be detailing the installation of the '07.5 Dodge 68RFE 6-speed automatic into my '96 Dodge 12v - the instructions should be compatible with any chassis not using the 6.7 engine - at present, all the pieces are gathered, and each challenge is being addressed as it arises -...
This is the FLEETGUARD fuel filter cannister used on the CTD engines. The filter element is top-loaded for convenience, it has a built-in thermostat-controlled fuel heater, Water In Fuel sensor, and WIF drain valve. This '05 version has the machined bosses on the inlet side for the obsoleted...
This is the in-tank lift pump module Dodge adopted for the '05^ CRD trucks, with similar factory-available retrofit to earlier CRD trucks, and VP44 trucks back to 1998.
Rated 5a and 10psi, it is a fully submersed, draw-thru when fail rotary-vane type pump, capable of maintaining rated pressure...
