I have gasoline leakingfrom rear by drivers side althought gas tank is on passenger side. What can be cause and how much should I expect to repair

You could have a line break or a bad connection to a faulty fuel filter. Driving the vechicle would be dangerous till this is taken care of. Need to locate the leak first. It could be here

Fuel pressure lines and return lines may follow the right side going up to the fuel module that is on top of the tank. If it leaks only when the engine is running I suspect that one of the lines could be damaged. Suggest you have a professional shop check it asap for safety sake.
i agree on both very risky to drive and get it looked at asap
