[DML] Re: TESTING THE FUEL ACCUMULATOR

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

>From the outline you gave it sounds like it is a good procedure.
Accumulators are generally good or bad, there is no in between. If it
leaks out of the small connector and it doesn't hold rest pressure any
length of time it is garbage. You sometimes also see small chunks of
black rubber from the diaphram coming out so you KNOW it's dead. You
only need to do the off-car test procedure on accumulators that are
not in the car. They are easy to test in the car if you have the
pressure gauge set-up. BTW air leaks faster than liquids so using a
gas (not gasoline) will show up smaller leaks. Gases are compressable,
liquids are not so timing the rest pressure is not going to be as
accurate using air. Since you are only interested in a go-no/go test
using air should be OK. Safer than using gasoline.
