Sounds more like algae or dirt in the fuel tank, plugging the fuel pickup screen.

Temporary fix is to blow back down the fuel line into the tank and check for bubbling in the tank. Warm temps, damp climate, for sure you got algae. Permanent fix is to clean the tank and use algicide in the fuel, make sure you don't get water sitting on the bottom of the tank.

Dirty fuel will plug the fuel filters. You can replace the little in-line filter with any fuel line filter that will fit, it doesn't have to be the clear one, although that is nice. If the clear filter is black inside, you have a dirty tank or a load of bad fuel -- get some new filters on the car and see what happens. No fuel will cause all sorts of trouble.

Also, check the fuel lines from the tank to the IP -- if you have cracks or tears, you can be sucking up air instead of fuel. You won't have starting problems in Mexico unless you are in the mountians, but will have performace problems!
