[Diy_efi] New TBI install in older car

>Spark but no fuel spray....recheck fuel pressure.  Make sure it's fuel and
not air in the lines.  IIRC, some of the frame-mounted Ford pumps are meant
to be strictly booster-pumps, and won't create enough suction to actually
draw fuel out of the tank.  The full-size vans and some trucks actually had
2 pumps, one in the tank to provide volume and one on the frame to provide
pressure.

My truck is setup like this. It actually has 3 pumps, 2 lift pumps (one in
each tank) and a pressure pump. The pressure pump will work by itself though
as long as it's close to the tank level. It might not be able to self-prime
though.
