I am the recent new owner of a 1978 diesel. As with an 25 year old car there are things that need replaced before they REALLY go bad. I have both oil cooler lines that need replaced and did a search and somebody mentioned that it's a nightmare of a job to do myself, but if I buy the wrench it doesn't seem that hard...... just messy. Is there something I'm missing???? Seems like you just take the old ones off and install new ones.

Secondly I have diesel return lines that are leaky so I'm also ordering those The precut ones with new gaskets. I'm not quite sure how these are removed and installed either. Anybody have experience?

Thirdly a PO has installed a Rayco Diesel/Water separator to my fuel system. On the door for the gas(diesel) cap there is a sticker that says do not use fuel additives and to drain the water daily. Well I have no idea how to drain this water... or even what this water is. anybody know what this is about?????

Long post but I'm a newbie to owning a car in general let alone a diesel. It's my first car that I'm paying for. Any help from someone older and wiser is greatly appreciated. Thanks!
