RE: [doc] Re: Injector Cleaner

["Chris Parnham" <secretary@xxxxxxxxxxxxxxx>]

As this subject is now nearly through, I agree with Dave Howarth who
regularly give his cars a good dose of injector cleaner first thing each
season. Never caused us any problems up to now......but I possibly give
it a miss with Herman.....freshly baked in the Good old USA......

No, you said and a quote again " The accummulator is in the fuel line
prior
to the filter so any crud will always accumulate (cough-cough) here."

"any crud will always" are the key words here.  Crud will not always
collect
in the accumulator.

The accumulator's first job is to help smooth out any pulses in the flow
of
the fuel, this is achieved by passing the fuel through a series of
baffles
and into a chamber giving it slight capacitance and a much smother flow.

Its other and possibly more important role is to maintain pressure
within
the system when the fuel pump has been switched off.  Nothing to do with
collecting crap in the fuel system.

I'm not into trying to prove who knows more about this or that I'm
smarter
than someone else. I'm just trying to stop poor advice leading to people
wrecking there cars and costing them an arm and a leg to fix.  A
metering
head can cost over 500 quid to rebuild and injectors also cost a bit.

We all agree that a clean fuel system means a healthy Delorean but if
everything is not clean then adding detergents and allowing the crud to
dissolve and move around the system is just bad advice.

On a lighter note we have accumulator's, injectors, fuel pumps, fuel
lines
and filters available just in case :)
