What does "no oil in the tube" mean? There is no oil in your oil line? Check for kinks like a previous poster mentioned.

Before you go through the trouble of pulling a valve cover and making a mess, you can check your dipstick, wipe it clean and re-check the level. Then run the truck a minute, shut it off and re-check the dipstick. Oil should have found it's way farther up, much farther. Just pulling a valve cover and seeing oil squirt out isn't a very good indication of the amount of pressure present, neither is checking the dipstick, you will need to check your gauge and wiring before you go further than just looking for oil flow. But at least you know it is flowing somewhat.

The tube is the little plasci tube from the sending unit to the gauge. There are only small pockets of oil not a steady stream of oil in the tube.

Ok....then trace the line back to the sending unit, not really a big deal. If you don't find anything, then you may have other problems.

HERES WHAT I DO... I'M NO EXPERT.. BUT HAVE BUILT 4 OR 5 DOZEN SMALLYS. GET A DIFFERENT GAGE. JUST PUT ABOUT TWO FEET OF LINE ON IT. SCREW IT INTO YOUR PRESSURE GAGE HOLE JUST TO THE LEFT OF YOUR DIST. TAKE A PRIMING TOOL (THERE EASY TO MAKE OUT OF AN OLD POINTS TYPE DIST. JUST CUT THE TOP OFF & REMOVE THE CAM DRIVEN GEAR) , PUT IT IN THE DIST. HOLE, & TURN IT AT LEAST 500 RPMs WITH AN AIR DRILL FOR A COUPLE OF MINUTES. THIS WAY YOU REMOVE ALL DOUBT & YOU DON'T HAVE TO START YOUR MOTOR. YA GOTTA HAVE OIL TO KEEP ALL THOSE LITTLE PARTS SLIDING OFF OF EACH OTHER. THINK OF IT LIKE A HUMAN BODY WITH NO BLOOD FLOWING....... WON'T LAST VERY LONG.
