Before throwing more and more parts at the problem, first thing to check is fuel pressure, if it's OK, then that isn't the problem. It could be------a plugged catalytic converter, a failing ignition coil, bad plugs, distributor cap, ignition rotor, cracked/defective dist. cap, ignition module. The list can go on and on. Start with the basics. When was the last time a major tune up was performed? Smog check? We can minimize costs by figuring out the real problem first. If you are adamant about the pump, it's in the gas tank and you will need to drop it out of the truck to change it. Good luck

Where is the fuel filter on a 1994 Mazda b4000 pickup?

Driver side frame rail right where the door is. It's held in by a large hose clamp. It has 2 white plastic clips . 1 on each hose of the filter. When removing have a container that can hold gas ready because about a pint of gas will come out. Make sure new filter comes with new clips. I don't recommend using old ones. After new one in place turn key on and leave in run position for 20 seconds so filter can gill with fuel before starting and inspect fir leaks.
