Pressing the pedal down, puts in clear flood mode. Any applicable trouble codes? Did you use a gage and check correct fuel pressure, also, see if pressure will hold for a bit, with everything off. If it drops like a rock you have fuel leak. Pull vac line off fuel pressure regulator, where applicable, if fuel runs out, you have a faulty fuel pressure regulator. You could have fuel injector leak?
Smell of your crankcase oil dipstick, if it smells like gas, either you don't change your oil and filter very often or fuel leak. There could be other issues? You have to start testing, somewhere.
There most likely isn't a problem. The fuel gauge works off of a reisistor board that's mounted on the fuel pump assembly. There is a arm with a float attached to one end. On the other end there are needles that touch the resistor board. The float level changes where the needles touch the risistor board and that changes your fuel gauge. Not all resistor boards read exactly the same, especially if an AC Delco pump wasn't used. The gauge is just reading off a little bit compared to your original one. Try filling up, resetting your trip meter and then driving a good bit. When you fill up the next time figure your gas mileage by dividing the miles you went by how many gallons you used. I bet your still getting around the same gas mileage.
to check it . wire at the fuel tank gauge unplug it the black and purple wire for gauge. put a variable resistor , fuel gauge is rated 0 to 90 ohms. So variate the resistor and see if fuel gauge move. if it does fuel sender have problem or inside tank wire
you will have to drop the fuel tank ,remove the straps while supporting tank,remove fuel lines and vent lines,lower to ground ,remove ring that holts pump ***. in tank.Be certain to change filter and strainer
float assembly, called fuel sending unit.May be able to access under the carpet in the rear or you may have to drop the tank. If you replaced your fuel pump you probably saw it.
anytime you can smell gas, you have a leak, not good to drive if you can smell strong fume and not safe to drive. check all fuel line and fuel filter connection. check gasket on intake manifold and your injector. The rpm goes up and drown erratically, check your distributor connections and the ground wires. If distrubutor has bad ground or conection can cause erratic behavior RPM guage.
