well then im going to assume its either a rusted through gas tank which should be replaced or one of the o rings connected to the sending unit is not sealing properly either way your going to need to syphen out the gas tank into an approved storage container and drop the gas tank down and out the bottom for further examination.... good luck :)

but to be sure i would take a clean peice of cardboard and put it under the car for the night right after you fill the tank and look for spots in the morning.... also if you drive almost a full tank and you open the gas cap do you hear a sucking sound?

That model had problems with their fuel lines rotting out right near their tanks as well,this was often cover by a plastic shields on the driver's side of the fuel tank. Best to put the car on a lift and check to be sure.

Suggested Repair

After filling the tank, place clean cardboard under the car overnight to locate the leak. Inspect for a rusted fuel tank, a leaking sending-unit O-ring, and rotting fuel lines near the tank, often under a plastic shield on the driver's side. Safely siphon fuel into an approved container, drop the tank if needed, and inspect the tank and lines on a lift.

Conversation Summary

The owner of a 1990 Honda Accord reports fuel pooling under the gas tank after the car is parked, with no fuel smell while driving. Experts suggest a rusted tank, a poor sending-unit seal, or rotting fuel lines near the tank, and recommend a cardboard leak test, checking for a vacuum sound at the filler cap, and inspecting the tank and lines on a lift.
