RE: Fuel Leak Perkins 135
Hi Max,* I think there is little chance of fuel leaking into the engine if it's leaking on the outside of the injection pump.* My Perkins 6.3544 had a leak I couldn't find until I cleaned off the pump completely with something like brake cleaner.* I then dusted all suspected areas with talcum powder, started the engine and watched closely with a bright light for the first sign of fuel.* Once the leak started, it was very clear what the problem was (loose injector pipe nut between the pump and block where I had a hard time tightening the nut after replacing the injectors,).* You can also get a flourscent powder to put in the fuel that shows up under UV light, and it works great.*
Quite likely Phil is correct, the new low sulfur fuel has caused a seal to start leaking.* There was a recent thread about just this problem on another Perkins.* Try the search function..............Arctic Traveller
