Fuel leak on second Fuel filter housing

I've got a drip on second fuel filter housing. The small one by the oil filter. It's hard to tell exactly where it's leaking from though. There's obviously the cap that's a prime suspect, but don't think it's that. Then there's the lines in and out that could be the problem, and then there's the cover on the front of the housing. Looks like it's held on by two bolts with a gasket. This looks like a prime suspect, but didn't know if there was a notorious spot that they leak. If the cover turns out to be a suspect in your opinions, what's involved when you remove this to replace gasket?

CLICK HERE and see if this is the piece you are talking about.
If it is, I would recommend installing that kit anyway, sine it was released to address a known issue with the stock fuel pressure regulator spring. The stock part weakens over time and could allow your fuel pressure to drop below 45psi. Injector damage can occur at 45psi. This kit will raise your fuel pressure to right around 70psi at idle. It comes with many of the o-rings you will need to cure your leak.

Yes NYC that looks like the cover I was talking about. It seems from what you've said I need to replace anyway, but are they notorious for leaking? Like I said it's hard to tell where exactly the leak is coming from. Thanks.

No, not really. When they do it is usually the keyhole shaped o-ring that failed.

Got the kit coming. Now as far as installation, can I install it in place? Do I have to remove housing? Just looking for any info I meet need to know to install correctly, and I don't get offended I mean any info. Thanks.
