Could be different internals. Look at it this way: Two MAP sensors (Diesel
and Gas)...both look identical but work on different calibrations.

Subject: DML: Holley 12-920 Question....

Ordinarily I'd call and talk to a Holley tech, but I'll ask this here and
see if anyone can figure this out...

I ordered and installed a Holley 12-920 in-line Fuel pump to replace the
Powerdyne supplied pump that recently died.......we swapped the pump out, it

fits with no issues at all......direct replacement!

my question is .....the old pump and new pump look exactly identical, right
down to the markings
and company that made them "walbro"

The old one was a 200LPH Pump supplied with the blower kit, the new one was
a Holley-12-920
that came in a white box with a Holley part number on it....it was supposed
to be a 255LPH Pump!

Is it possible I got another 200 LPH and not a 255 LPH?

Otherwise everything is Fine, the Dakota Runs the same as it did before the
Pump died...Perfectly!

I think I'm gonna call summit and see what they say....
