I posed this question a while back and the responses were similar. Seems we
have a bit of a dilemma. As our vehicles approach 20+ years the threat of
rust and crud in the pump increases while a pre-pump filter can create the
aforementioned restriction issue. I'm wondering if the restriction issue is
only a problem once the filter starts to clog. If so, seems you could have
the best of both worlds by changing it frequently. I guess the question is
at what interval and how do you know when it needs to be changed before you
encounter running problems? Assuming the condition of all tanks and the
amount of contaminants varies from van to van. But I guess for $5 for a
square filter you could order a stash and keep them on hand without too much
expense. Seems like cheap insurance for the expensive pump and round
filter.
Mike, your right on the money. Exactly what I do and was going to write.
Even though I recently installed a new tank on my Westy and do not have the
problem of rust in my tank, not yet anyays, I still run both filters and
recommend to all my customers to do the same for the above mentioned reasons. One
way to tell when it's time to change that small plastic filter before the
pump is to get accustomed to the noise your pump makes with a new filter then
when that noise changes it's time to change the filter. Restricted fuel flow
causes the pump to strain and make more noise. Otherwise just change them at
regular intervals. When removing them it will be evident how much crud they
have collected and you can base your change intervals on that information.
Just a note for those wanting all the info. With the above to filters in
place your Vanagon now has three filtering devices of the fuel. The screen in
the tank, the small plastic box one between the tank and the pump and the metal
can one between the pump and the injectors. Overkill ? Maybe but it has
worked for me. I would like to recommend the screen in the tank be removed as
it's pretty useless as there is no way to clean it other than changing tanks.
Why the manufacturer put the screen in there in the first place is beyond
my comprehension. A filter at the tank exit would have sufficed ! Whether
or not the new tanks we're getting have screens is a question that has not
been answered yet. Vendors have you any info on this ? The ones I get from CIP
made in Taiwan look to have the metal plate inside that hide the screen like
the original tanks but wether or not there is a screen in there cannot be
see without cutting open the tank. I sure would like to know and recommend to
the manufacture to LEAVE THE SCREEN OUT PLEASE !
