I went retro on my 90 GL wit ha mostly stock engine.  I wanted the fuel
pump to never see any rust from the tank or grunge from bad gas or vandals
putting something in the tank that wasn't spozed to be in thee.  I found a
Wix metal(part number escapes me right now) filter at my local parts place
and it works fine as a prefilter.  Obviously I use the factory metal filter
after the pump as well.  I added a "gas shut off valve" upstream of the Wix
filter in the line to make the filte chaning a lot less"fluid".  It also
doubles as a interesting theft deterrent should I park in a dicey
neighborhood on occasion.  I simply turn off the gas valve and if the would
be theif runs off with my van, he or she will get maybe a 1/2 mile or less
before the engine staves itself of fuel and dies for no apparent reason.
Yeah prolly a bit extreme, but effective.
