I believe the 190lph HP is the most commonly used around here. If I remember correctly I ordered the one for the '94-'97.
I just replaced mine yesterday and I was actually able to still use the original bottom retaining plate and all original hardware by using a small 1/4" spacer and a longer machine screw at the bottom.
Thread Hijack:
Does anyone know why the Walbro uses that little insulating sleeve? The OEM pump doesn't have a little sleeve and I've never seen anyone use it on their Walbro installation. Just curious.

it's not going to help you much if you can't control the bigger injectors....
FWIW, most of us using stand-alone ECUs use the stock pump and have plenty of fuel for 300rwhp....
it's all about chosing the right fuel pressure, injector size, and controlling device.
A 255LPH fuel pump is not going to magically unlock hidden HP, it's job is to supply the fuel rail with enough fuel for the injectors to spray, that's it.
So only think about a new pump untill:

So only think about a new pump untill:
- Your's is crap
- Increasing the fuel pressures in the rail beyond 70psi.
- Your current pump cannot flow enough Gal. / Hr. at a given pressure
