Well it seems I get one thing fixed a one more breaks. My fuel heater is leaking. Will a simple fix like silicone work or do I have to take it apart like I've seen in other post. Also will getting a fass system get rid of the fuel heater/filter all together?

Get rid of the fuel heater.......it's only 300 watts; combine this with a fuel flow of 30-45gph and you will find it raises the fuel temp less than 1 degree (c or f). Check out Infidel's posts; he has some info on the delete for it; you already have everything needed, just get rid of the heater and the big hex-fitting in the middle.

Chariotdriver thanks for the reply. I have looked through 20 pages of Infidel's post and could not find what you where referring too. Could you point me in the right direction, on how to do this fuel heater delete. Thanks. Jdw123

Replace first-gen heater with second-gen

Go into the firsst-gen forum's sticky and look around. I couldn't find the heater delete thread. I think it is a 1036 NAPA oil filter, that you can use the square-cut o-ring out of to replace a bad one, on a first-gen.

It's overheating wires that makes them leak, for preventive maintenance unplug the heater and leave it unplugged before it leaks.
You really don't need the heater as long as you are certain the fuel you are using is winterized for your climate.

Man I wish I would have known about this fuel heater problem, before it became my problem. Thanks guys for all your help, and thanks infidel for the link on how to fix it. I think I will replace out my lift pump and fuel filter and just get a fass system. I have already replaced my lift pump twice, and I don't want to mess around with faulty parts any more. Let me know if that would be wise or not. Thanks for the replies.

So I had fass fuel system installed, and I am happy with it so far. It is a very solid fuel system. Mostly it gives me piece of mind knowing that I will not have to worry about lift pump failure and leaking from filter housing. Well worth it.

You don't say what year truck you have but if it's a 12 valve with mechanical pump you can't get much more reliable.
As long as you get an OEM from Cummins, which also is the cheapest place.
Generic auto parts lift pumps don't last.

Sorry, it's a 99. The stock one was replaced with an OEM. And that one again four months later. I had a warning light installed that would light up if the fuel pressure went below I think 5psi. This was after the first one went out.
