I have a ranger. it is our familys third vechicle and it has a bad head gasket so until it gets fixed we dont drive it much. but i go out every few days and start to keep the cobwebs blown out. YEsterday i let it run out of gas on its own. But today i noticed when its running gas starts running down the tank underneath it

im not sure if that just started or it was doin that b4 yesterday. it onluy leaks whiel running. Anyone know what it is? im woried for fear its the fuel pump ...
