The MAF is calibrated for the 42lb injectors.... other than that, i dont know how it is calibrated....

fuel filter was changed about 3 weeks ago.... however the filter on the bottom of the fuel pump looks kinda dirty but it cant be that old.....

There might be a problem with the snow kit.... i dont know how to adjust the pressure on the pump, i know there is a pressure adjustment on the pump itself, but i dont know of a way to actually know what the pressure is... i could be pumping too much in therefore "quenching" my spark...but if that were the case, how could my AF ratio be 12.5 still i would think it would be much more rich

i didnt check for codes but i dont have a Check engine light either

i have looked under the hood after i turned the car off and system holds fuel pressure after the car is off.... hold long does it hold? im not sure, i will look into that

how do you check for a bad regulator? it seems to work... i can change the fuel pressure with it



on the 2 tubes coming out of the fuel tank above the fuel pump.... one is fuel out, what is the other one? extra fuel back in?
