RE: [DML] Re: Fuel filter (tank pickup)

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

The original fuel filter screens that I have seen in my beginning years
working with DeLoreans were epoxied in. What is unfortunate is that the
epoxied the Permatex sells and states on the container is good for gasoline
over time isn't. That is why when I discovered that they were failing I put
out a memo on the DML that I would exchange or replace them. Very few took
me up on the replacement. Even since then I haven't had any noticeable
amount failures on pumps or screen that have been contributed to the epoxy. 
Long since ago I went to a very simple fuel baffle system that I now use the
snap on tube on the bottom of the pump and filter screen that snaps onto the
bottom of that. This way you can change the filter screen at will the filter
screen from anyone's part you have or buy.
Always trying to improve what we have.

Every one of the epoxied filters I've seen has always reacted to the fuel. I
never trusted that setup so years ago I started having machined aluminum
adapters made to eliminate any chance of failure. As far as I know both John
and DMCH used epoxy bonded filters until they (DMCH) started buying my
adapters about three years ago. They've since had their own version made but
my point is any one who thinks they have one of these filters in their tank
should have it replaced because IMHO it can easily cause pump failure.

BTW I never sold any of the epoxied filters so if you bought one from us
please don't call me to ask if it's safe. Getting ten cars out of here
before Gettysburg is taking up every waking minute..except the last three!

These pick-ups may have been OK at least until the gas companies
started putting all kinds of additives including Ethanol into the gas.
You have to be particularly careful these days with fuel systems. The
older cars were never meant to have to deal with this stuff. You may
be able to salvage the pick-up. Remove all of the loose, crumbly stuff
and use an epoxy that is more tolerant of the newer gas blends. If you
find a lot of dirt in the tank you should consider changing the fuel
filter. Since the Delorean has a recirculating fuel system all of the
crud eventually winds up in the filter. I also found it hard to tell
exactly what you were trying to show us with the picture.
