T&T: 2 10 30 Micron Filters??

[LA Licata]

Phil.

How long have you had your engine?

Have you had any fuel problems that otherwise might be explained by  
fuel starvation?

If you can run at WOT at the correct rpm for a while without any  
problems, and you can run your "unloaded at the dock test" also  
without any problems, then while on theory, he may be right, I think  
you can be comfortable with the setup you have because it is working  
for you.

The 30 vs 10 vs 2 micron argument has been hashed on this list many  
times. My personal opinion, mind you, very personal, is that if what  
I have is working for me, than there are plenty of other things not  
working that need my attention...

several problems, he was quite stern about the fact that I shouldn't  
be using 2 micronfilters... His reply was that the fuel lift pump  
doesn't handle the increased resistance well.   The lift pump pushes  
much, much, better than it pulls, and it is pulling on the primaries  
and pushing on the secondaries...
