4ks fuel filters

[Andrew Finney <afinney@tamsconsultants.com>]

Hi all,

but I note that there are two (2) other filters back there, inline
with the
metal one.  The other filters are both smaller generic plastic
types.  What's 
up with that?  Its not normal is it?  (didn't see them in my
manual)  Maybe
an attempt to save the expensive ($30) can by precleaning with
cheap disposable
$2 rigs?  An other ideas?   If they're not supposed to be there,
by instinct is
to remove them.  OTOH, they probably weren't put there for
nothing?   Lastly,
since I assume there's an in-tank pump, can I just get rid of
them without
spilling a tankfull of fuel all over the place?  Thanks for any
tips.

regards
roger

I'm pretty sure that the 4000 series was similar to my UrQ, and
as I remember it, my '82 Coupe. There sould be a primary
plastic fuel filter that's only purpose is to protect the fuel pump.
Then there is the fuel pump, located under the car, then the
pressure accumulator, which is a canister thing (new ones are
olive drab in color) and then the secondary can-type fuel filter. I
think that it would be rare that the primary is clogged.
Common that the secondary would clog. As for other plastic
filters, probably add-ons. 

Make sure you crimp off the rubber fuel line before the primary
filter before you touch anything or you'll be eating gas. Good to
have a backup plan, such as rubber vacuum caps and hose
clamps to seal the line if you'll be working for a long time, in
case the crimping isn't 100% effective. Good luck.
