[Diy_efi] Question about TBI fuel pressure

[Fehn, Ron G]

the walbro 190 is the favorite for thirdgen.org members over stock TBI
or even TPI.  occasionally there is a group buy.  may be on now?  do a
search.

Jim, Use an older in tank fuel pump and sensor form a Buick or some 
other GM. The TBI
components used on the GM trucks & cars  from ~ 87 on are very plentiful

& cheap.
The Aztec pump you are contemplating is a pump& fuel level sensor 
combined that
is very pricey.  The in tank GM TBI fuel pumps can be purchased for $28 
to $45,
you also need to scour a few junque(high class junk) yards for various 
other TBI
components.  Most TBI & TPI use a fuel pressure regulator that you will 
also need.
Don't forget to run a return fuel line back to the fuel tank, the unused

fuel is
circulated back to the tank.  Look at access to the fuel tank pump & 
level sensor,
you may have to make a covered opening to gain access later on, much
easier than dropping the tank.
Good Luck,
