Is the gauge glycerin filled so it doesn't destroy itself due to vibration?

How quickly fuel/air mixture can be delivered is important for high piston acceleration conditions. See this article http://www.epi-eng.com/piston_engine_technology/piston_motion_basics.htm for a pr...

Didn't think it got that cold in Texas to need a diesel heater ~ On December 18, 1983 the temperature in Dallas went below freezing and stayed that way until December 30th. - 295 hours. Pipes froze all over the metroplex and ice dams formed in the gutters 2-3 ft. wide and hundreds of feet long. Ft....

With this auxiliary 12v alternator, don't you also need a separate 12v battery to go with it? If you try and connect it to one of the batteries in the 24v series string, that battery will always be at a different charge level than the other. Without the extra battery you couldn't start the vehicle d...

Life is more exciting when the target is constantly moving!

I need to get out a mirror and inspect my booster. I was using the "eyes" in the end of my fingers and didn't feel any grommet in the housing. I pushed and pulled on the hose to see if the nipple would wobble around, and it didn't. My truck is a '79 - no idea what differences there are in ...

An Austrian 712M that was on the Dorotheum Auction site went for $19000 USD. Currently there is a very nice 712M on ebay with 3 days to go. http://www.ebay.com/itm/221897129113?forcerRptr=true&item=221897129113&viewitem= . It is also listed in the Classifieds forum: http://real4x4forums.com/...

On my truck the booster has a nipple that appears to be a part of the housing. The check valve is inline. The parts are detailed in group 08-01. If you have an open hole it may be a booster housing that was replaced at some time. Many check valves can be found that fit into the housing with a rubber...
