Perkins 4-108 Fuel Leak

anyone having any dealings with these type of engines, i have a fuel leak, i can feel the bottom of the injector pump it seems that the 2 fuel lines that i can see are not the problem the other 2 are pretty tough to get to, the inside bottom 1 is not impossible to get to, the other 1 on the top next to the block looks to be the hardest maybe with the manifold off i might be to get at it, if not am i correct in saying the pump will have to come off any input would be helpful...........thanks

As I remember when I had one of those beasts in my boat, I had to get a couple of 10mm box end wrench's then cut a slot in the box to slip over the tube to get to the nut. I also had to replace a few gaskets on the pump. Eventually I got everything dry only to loose the tranny 200 miles later in the middle of nowhere.

the hex nuts that mount the pipes to the pump should be 17mm. your best to pull the manifold where everything can be visualized.

I think what CelestialSailor is talking about are "flare wrenches". They have an open end to go around the tubing. Easier to buy the correct thing than to cut the end off a box wrench I think.

I had a 4-107 with a CAV leaking pretty badly, ended up being the upper body gasket, pull it and reseal.
