6.2 detroit diesel
Hi yall,

I noticed a wet spot under my RH fuel tank the other day, and got down there to investigate. I noticed a small diesel leak, coming off the underside of the tank. I tried to search for the source, but to no avail. Anyone have some tricks for tracking down a fuel leak? Or any specific places that I should be looking? It's not a terrible leak, only a few drops, and I had been parked for a few hours. But I'd still like to nip this in the butt before it becomes something I really have to worry about

I'd try putting some fluorescent leak dye in the fuel, and maybe you can follow it with a UV light.
