Didnt mazda put these things through their paces when they were testing these cars!!! Maybe they should start employing a few of us to find the little bugs like this!!! I mean who wouldnt accept a job of thrashing around yet to be release cars... and getting paid for it!!! Hell i'd do it for free!!!
What do fuel pressure regulators do? Rising rate regulators or what ever they're called??? Is there some sort of gauge that i can hook up to get a reading of the amount of fuel the engine is getting? (without spending the money on one of them air/fuel mixture ones by autometre?
FPR: it restricts or increases the fuel return making it possible to adjust the pressure at the fuel rail. (this will not solve the problem)
Gauge that tells you the amount of fuel the engine is getting: Fuel pressure gauge, the cheap ones are mechanical, the fuel get plumbed right to the gauge, and the gauge should not be installed in the car, on the edge of the hood (in front of the steering wheel). (this will not solve the problem)
Air/Fuel gauges, they will give you a rough readout of the amount of fuel thats still left in the burned exaust after the turbo. (this will not solve the problem)
You dont need a gauge to tell you when this happens, the cars lack of power lets you know when it's happening. These gauges serve a purpose just wont help with your problem.
Possible sollutions: Modifie the tank so the fuel returns to the pump quickly after corners.
Add a second fuel pump to the tank or pull the filter off the pump and add a short piece of fuel hose, T it off and run two little pickup filters .
Run an inline fuel pump and filter, then make sure the pick-up in the tank is in a spot that cant run dry.
Extrem and cheap (not the best way but would work), Take a rubber mallot and put a dent on both sides of the tank bottom making it so the gas has no where to go but the center.-This would give you innacurate fuel gauge reading when the tank is low, make the tank hold less gas and run dry quickly when the tank is low. (I had a tank with a few dents in it, was like that when I got it, looked like someone ran over a couple soccer balls. It ran dry quick!.)
There are surrely more sollutions, search the web.
