Water in Fuel

pat sublett · Feb 2, 2012

I know 3 people that ruined their diesel engines this week because of water in the fuel that was purchased at a local Exon station. I don't understand how enough water got by the filters to ruin the engines. This station is on I20. Probably a lot of people had problems.

I have never seen an engine destroyed water unless a person runs it so long as to make it so oil does not do its job so in this case that would or should only shut them down so a simple cleaning of the fuel system and yes maybe the big hurt rebuilding the injector system but that should not destroy the whole engine

I'll beg to differ. Several years ago a neighbor lady drove a Olds 5.7 diesel through high water on roadway and the air intake was low enough to take in water. Bent some connecting rods in the engine. Seriously I agree water in fuel will stop up filter and could seize the inj pump if so equipped but not ruin engine.

There are 2 kinds of pump filters; hydroscopic and particulate. Also tank systems today have a Veederoot condition monitoring system. It tells you when there is water, etc. Most stations don't use the water filters. When you have a slow running pump beware. If it suddenly speeds up it usually means that the filter just blew out. Then you really get the garbage from the tank bottoms. It all comes down to cleanliness, some care and a few don't.

Sucking a bunch of water into the air intake will ruin pretty much any engine, gas or diesel.

Water in the fuel will ruin the HPFP (high-pressure fuel pump) on a modern common-rail diesel, the lift pump, or the injector pump, long before it ruins the whole engine.

The cost of repair for any of these is pretty steep. It seems like you're paying for the whole engine.
