Default Fuel pump question

The fuel pump cross ref is screwed up.
Next-- The replacement pump cross reference is also a mess.
The NA pumps have different specs than the NB pumps.
A replacement pump is made by Walbro (and others) the problem is basically
determining which one by part # to use.
To add insult to injury, different sources of Walbro pumps use different
numbers for the same pump.

On a replacement pump--
The pump "kit" is the same for the NA & NB. ( Filter bag and misc hardware)
The pump is strapped to the pump bracket instead of screwed to it. A rubber
sleeve is usually supplied to help reduce noise. It also allows the strap to
work properly. The strap may be metal or even a plastic "wire tie" that
works ok when exposed to fuel.
The "pigtail" from the factory pump is spliced or modified) to fit the
replacement pump. (The connector and terminals may be different on the
replacement pump.)
Some variation in length is allowed. The bottom of the replacement pump
needs to have the same physical layout as the factory pump, in order to fit
the support bracket.

I used a Walbro 190hp on my 99.

If you have a 99, you should consider replacing the bypass regulator
attached to the fuel pump bracket with the newer version. (Tech bulletin)
