They dont say #342 on them - the #'s are gound off

I now have this pump, on the dyno my car was leaning out to 12.5+ no matter what we did with FP or duty cycle, pulled the car off the dyno swapped in that pump and and logged a run down the road, 10.0 A/F! I run that pump and another external 255(AMS kit) and now have plenty of fuel even on 1000cc injectors.

So please help me understand...
Is it a modified Walbro or another brand of fuel pump?
I'm asking because i heard of many Walbro pumps failure...
Is it possible to know the BR pump's flow at 73 and 80 psi, at 13.5 volts?
Tia.

It's a modified walbro pump that flows more than the regular walbro 255.

Modified Walbro pump = a way to charge more for the pump hehe. Plus it says it outflows more at 100psi, but no one runs 100psi of fuel pressure on a walbro. I would like to see what it does at 43 to 45 psi when injector spray pattern is optimal.

Does anyone know offhand if the Walbro 342 and Walbro 340 pumps are interchangeable? Do they have the same external dimensions and flow #´s? Sorry, if this veers a bit OT. I guess I wanna know if the 340 will work on our Evo´s.
