Guys, I don't understand why you are installing filters AFTER the  pumps? I sell large SEPAR diesel fuel filters and I always recommend  all the filtering to be done before the pumps and out of the tanks.
 Any water or debris if it's allowed to reach the pumps, will be  beaten into smaller particles and may be PUSHED thru the filter, or  even will damage the pumps.
I personally suffered on my boat by frequent engine stopages in the  worst of times, only to discover that the manufacturer have installed  a screen on the pick up tube inside of the tank, where can not be  seen or cleaned.
The same manufacturer had to fix or replace number of engines only because he installed the fuel pumps BEFORE the filter. Any water in  the fuel was beaten in to fine emulsion and pushed thru the filter  into the injectors. Results were rusted injectors, rusted high  pressure pumps and more.

Ernest,
   My opinion also !! There is a potential 90 psi  surge pressure  from
healthy EFI pumps........I do not believe any of the cheap glass filters
are rated that high !!

I love this list.  I had not thought to check the pressure rating.   I just assumed that a filter could take the pressure.  It's not  like 90PSI is difficult to design for.  But after Mark suggested  it, I went looking.  Sho' 'nuff, no rating.

Any of you carbeurated guys want a pretty glass filter for 3/8"  hose lines?
