got a pretty good leak going on, apperantly at the return tee at the back of the block. i have gone under the truck while the engine is idling but cannot see it leaking. it is however soaking wet. the fuel is coming down and hitting the front drive shaft and is being slung all over the place. when i park i leave a small puddle of diesel and can smell it pretty good. since i cannot see it leaking i am assuming the engine needs to be under load for it to leak.anyway its going to be a pita to work on. so anything yall know to make it easier would be appreciated. i am going to buy a new tee and replace it while i am back there. is there anything else that ususally fails in that area? iam pretty much going to be committed once i take it a part. no spare vehicle and no gopher.
