general problems of the 1998 Oldsmobile 88

I just bought this used car on Jan 1, 2013. I noticed a smell from the car but wasn't sure what is was and bought the car anyways. Well a couple weeks later my boyfriend was checking my fluids on the car and noticed a fuel leak under the hood, so we went to auto zone and bought a fuel line that cost around $30, he put it on, still leaking, well we figured since the fuel line that we bought wasn't precrimped it wasn't going to work, so we went to the junk yard and got the exact same part off another 1998 Oldsmobile 88, figured since it was precrimped it would work, not the case, fuel still leaking under the hood, so we went to the chevy dealership in nashville and bought the very last fuel line in the state around $120, which the difference between this one and the other two is that it is 6 ft. Long, so we put the new 6ft fuel line on, well it stopped leaking under the hood, and discovered 1 week later that my vehicle was leaking fuel under the car by the back passenger wheel, so we put a fuel pressure sensor on the vehicle figuring that would control the fuel, because we heard that if that goes out it will cause fuel to leak from weak spots, well almost 4 mo. Later my vehicle is still leaking gas from under the car by the passenger back wheel. This is my daily driver back and forth to work. I found a recall on this and would like my issue to be addressed.

While entering my garage at a slow rate of speed and my foot on the brake, the car suddenly surged forward. This has happened 3 or 4 times when coming to a red light or stopped vehicles over the course of the year. I remember the Audi that had the same problem. I really thought I'd end up in my living room. I quickly put the car in neutral on all occasions. It seems like the transmission isn't dropping down to it's low range. Help.

Consumer indicated recall on the fuel pressure regulators failed. Dealership indicated to consumer they were not no responsible for the problem.
