Fuel Leak...can't determine the cause...Help please

[Monroefiredog1]

I have a 02 Dodge CTD that has a fuel leak that is mixing with a little oil leak and looks bad. I have checked all over the engine and have yet to determine the location of the leak. It appears that the left rear side of the block is washed clean and looks wet but I can not determine the location. I have checked all of the lines, lift pump, and injector nuts, but don't see any leak, but it is showing up on the bell housing like a rear main seal leak. If anyone has any ideas, please tell me....I have been looking for this leak for over a week but can not find it. Please Help!!!

Check the fuel return tee on the back of the head

turn tee, but no


I did check the return tee, but I cant see the fitting on the rear of the head. Do you by chance know what size wrench it takes to tighten the fitting?

Don't know the size but it is a banjo bolt with washers so don't go overboard tightening or you may snap it off. Maybe the same size as the one on the return overflow on the side of the VP.

There's a single banjo on the back of the head and a tee fitting about 8 inches just below it. The banjo is notorious for leaking due to the constant changes in temperature, and the tee fitting is rubber seals which can leak if they get loose over time. The banjo is 18 ft lbs but the tee fitting is more just snug them up.

Here's a diagram that hopefully help identify them.
