Since I got my car back from DPI 3 weeks ago I've clocked just over 200 miles. A few days ago I started to get a fuel smell inside the car. At the same time I noticed the fuel pump got VERY loud. Outside the car I can't smell the fuel - only inside. I've taken the cover off inside the trunk and I can't find any leaks. When the engine is running and I'm sniffing around the fuel pump, the smell is present but it's much less noticable than it is inside. Today I heard a very strange liquidy squishing/gushing noise from the centre of the car while driving. It made one loud SPLORSH kind of sound which lasted maybe 2-3 seconds. Is it the accumulator?

The car drives fine, accelerates fine, revs fine all the way up to about 6,000 rpm. I have Hervey's pump & baffle.
