I got adapter fittings from Earl s for Tracy s pumps and plumbed them in parallel.  They don t allow backflow, so you don t need check valves.  I takes a lot of fittings by the time you go from one line from the tank, split to two pumps, back together, put in the filter, and the pressure sender block.

 

I d just suggest being a little selective on the filter.  Downstream from the pumps I think you d want less then 50 microns, rated at more than double your max expected flow to allow for some blockage; and I think in the long run, one that has a cleanable element.

 

K&N made some nice filters that they have discontinued.  Same for Edelbrock.  I ordered filters three times before I actually got one, and ended up paying over $100.  There are stock filters that have AN fittings; you might have to search or find someone at a parts store that knows something.  After I bought mine I came across one, but now I don t remember what is was for; maybe Porsche or Mercedes.

 

Mine is Peterson 600 series, and I bought it from Motorsports Supply in Colorado; about $105.  Probably more filter than needed, but hey, it s for my airplane.

Al,

Thanks for the filter and fuel system info.  Yes, I realize the large number of fittings that will be necessary to get the fuel system functional.  That's why I am trying my best to get it right the first time around.  I like the GM efi fuel filter because of its robust construction (welded stainless steel), application (big American V-8's) and availability (Auto-Zone, Pep-Boys, Wal-Mart, etc).  If I plug one up in Flat Rock, TX, I want to be able to get a replacement at the nearest Wal-Mart.  The GM filter is less than $10/ea, so I plan on changing the old ones out at every annual.  The only problem was the Saginaw fittings, which has now been resolved.
