NOTE: Do not try to use an automotive type gasoline engine compression
gauge on a diesel engine. They don’t normally have the range necessary
for diesel engines and there may be an issue with the hose bursting.
Normal compression for the Briggs & Stratton 3/LC diesel engine is as high
as 500 psi (35 bar). The 19566 3/LC Diesel Compression Tester is capable of
reading 1000 psi (70 bar).
