    Engine Pre-Lubricator

    Simple and easy to use, fill the tank through the multi-purpose filler and dipstick cap using the specified engine oil for a maximum of four quarts. Once filled, locate an oil pressure outlet on the engine block and adapt the outlet hose with the proper size adapter. With the plug valve turned off, pressurize the tank to a maximum of 120 psi then turn the plug valve on for a few seconds or until oil flow may be seen from the rocker arm assembly. Once all the air has been released with the equipped Schrader valve, the tank and hose assembly may easily be removed.


    • Some engine may require a metric adapter fitting

    Rated 5 out of 5 by from Excellent Worked great. Was a lot more heavy-duty than I was expecting, which is a good thing. I used an air hose quick coupling between the end of the hose and the block to facilitate quick connections.

    Rated 5 out of 5 by from Excellent Unit worked perfect for prelubing engine. 4 quarts was way more than enough oil to get the engine lubed up and the air purged. Well worth the money to know your engine is primed before you hit the key to see if oil pressure builds on your new engine.

    Rated 4 out of 5 by from Zero operating instructions! I purchased this to prelube my LS3 376 crate motor. Price was 1/2 of the Melling Preluber which looks the same and operates on the same principle. The quality was good and it works as described if you can find someone who knows how to use it. The operating instructions leave you to guess how it is supposed to work. The instructions say, "Included with the unit are the most popular two adaptors to fit most engines." That is false! I had to go buy a fitting to use it on my LS motor. ...and how many million GM LS motors are there? Give me a break. And the instructions say, "The tank is then pressurized using your air compressor." Great: How much pressure? And then the really big issue. Does it work when it is upright or upside down? I called the Jegs Tech line...they had no clue. I called Federal Mogul who manufactures the unit and talked with Hank about the same above issues. He had no idea either. Here is the secret learned from trial and error. 1. Don't bother to try to measure the oil in the tank with the built in dipstick. It is almost impossible to see where the oil level stops. An engine dipstick works a lot better. 2. Use the unit upright. 3. Add 4 quarts of oil through the top of the tank, with a funnel, after removing the built in dip stick. 4. Put the dip stick securely back into place. 5. Add 50 to 55 pounds of air pressure in the tank with the line valve closed. 6. Use a dial type air pressure tester and hold it in in place on the schrader valve so you can monitor the tank air pressure. 7. Open the valve on the oil line. 8. Watch the tank air pressure go down to about 30 pounds then pump it back up to 50 to 55 pounds. Continue doing that until the tank weight is close to what the empty tank weighs. Plan to leave at least 1/2 quart of oil in the tank so that the tank doesn't go dry. (It is a pain to pour out what you don't use but it can be done). It shouldn't take more that 10 to 12 minutes to move the oil from the tank to the motor if you keep at least 30 pounds of air in the tank. Lastly, don't bother to ask anyone who sells these how to use the T40. They don't know. Follow these instructions and you will be successful. Be sure to release the air pressure via the schrader valve before you remove the built in dip stick.

    Rated 2 out of 5 by from Doesn't prime a Pont V8 I tried priming my engine but this would only push 2 quarts of oil. Also, the entire hose has to be rotated to tighten up the hose-fitting connection.
