RE: [DML] Re: Fuel injector cleaners in gas tank ----Noooooo don't do it!

["John Hervey" <john@xxxx>]

Jordan, I take a different approach on the injectors since I work with fuel
distributors and fuel systems all the time for Deloreans and I will say
other exotic cars. I use a chemical called Berrymans B12 that you can buy in
almost any auto store or at Wal-Mart. Sometimes it's best to let a sleeping
dog lie and by using a chemical that Dissolves the varnish a little faster
doesn't hurt. But, If the spray pattern from the nozzle of the injector has
over time affixed it's way of spraying and it's not the 360 degree or close,
then yes chemical could make it worse. Only because the varnish or something
over time has changed the nozzle spray pattern and the cleaner may make it
show it's real face. The thing that can't be done is fix the spray pattern
of the spray nozzle.. We can only clean the injector filter screen inside
and open up passages that may have been stopped up, but the pattern can't be
changes. Then it's time for new injectors and I can tell you I haven't
talked to anyone that has replaced 20 year old injectors or had them cleaned
that didn't see a big difference. Some people in the Porsche groups even go
as far as having them balanced and replace injectors with lesser pressure
for more fuel.
Just a FYI
