So my car's been leaking diesel lately and it's very noticable. I tried to fix the problem with new o-rings today and discovered a more serious leak where my supply line enters some device near the engine. Whenever I twisted the device with the hose in it, it was like a faucet

. Also discovered that the faucet had some bolt-type things in it...which were stripped. So that means either his mechanic or the owner knew and didn't tell me. If it were the mechanic, he would have said something to earn himself some cash. Or possibly maybe it was my mechanic who caused it to bag some cash!
Moral of story: used cars and diesels suck
