[DeTomaso] fuel pumps

[Larry - Ohio Time]

The only thing I mite add is to weld a small nipple (1\2" long) onto the end
of the valve going into the tank so that you are not taking the fuel and
crap off the bottom of the tank into the line.

One more comment...
Note that this 90-degree valve is only 2.75" top to bottom, which means the
installed height is less since it threads into the drain plug bung in the
bottom of the
tank.http://images.jamestowndistributors.com/woeimages/hardware/large/56744-

Therefore, there are no valves, hoses or fittings to dangle below the
Pantera's chassis or frame rails to risk being broken off by speed bumps or
stray road debris.

 Not a -8, but I plumbed mine with 3/8" (-6).
I went with the RobbMC pump and pre-filter on my 383 stroker Cleveland when
the Holley mechanical pump began leaking.I plumbed it from the bottom of the
tank with a 1/2" 90-degree stainless marine fuel valve from Groco.

and 3/8" steel fuel line from the pump to the top of the engine where it
goes through a fuel filter right before the carb inlet.

The biggest issue, regardless of where you plumb your fuel line from is the
restriction in the banjo fitting or elbow.  The stock banjo fitting on the
top of the tank forces all the fuel through a small orifice that's about
1/8" in diameter.  And many 90-degree fittings significantly restrict fuel
flow as well.  I went with the 1/2" Groco Marine fitting so it wouldn't
become the bottleneck that starves my engine for fuel.
