Fuel filter should be under the car, right hand side, under a plastic cover... approximately underneath the rear passenger seat.
If it's misfiring it could be fuel or it could be ignition. Since it's under load, I'd be more inclined to look at the electrics. Take the coils off and check the spark-plug connectors and leads. Look for any corrosion, dirt etc. and signs of arcing (grey lines etched on the coil plastic body around the plug/lead sockets.
Also make sure there is no oil in the plug wells. Remove the plugs and check their condition.
The fuel pump is unlikely to be picking up dirt... the filter should be stopping it. If you change the filter and that doesn't fix it, another one to check could be the fuel pump. I'd take the beast out of the tank and look for any splits in the pipe that carries petrol from the base to the top (outlet pipe).
If it's split you will be losing fuel back into the tank, instead of it getting pushed to the fuel rail. This pipe looks like injector hose but if you need to change it, you need to replace it with "submersible" ("in fuel tank") hose.. normal fuel hose will melt (only the inner liner is petrol resistant).
No bullets for Chaingun..
