liquid in the valley
A few days ago I was going to drain the fuel/water separator and happened to notice a pool of liquid in the valley. I removed it by soaking paper towels and removing them, probably getting out a half cup or more of liquid. I couldn't tell by looking at or smelling the liquid if it was water with some fuel mixed in, or fuel with some water mixed in. There was a fuel smell, but it looked more like water on the rags. It could have been rain, since we had rain the day before, but I thought water would have evaporated fairly quickly. Also, I rechecked the valley again and found it again had liquid in it after driving around for a week or so. This isn't oil, and there is no antifreeze coloration to the liquid. Does anyone have any ideas what this could be? I know there are fuel line fittings in that area. Could they be leaking, or perhaps the fuel filter housing?

the fuel bowl has a tendency to rot out on in the bowl under the fuel filter, i have a 96 psd and had to replace the fuel bowl because the bottom was ozzing fuel in the valey, i used JBweld temporaly on the inside of the bowl till i could buy a new bowl, I know it made out of aluminum but it still rots. mine was leaking where the drain is under the bowl, very hard to see, only leaking with engine running had to have pressure to leak.

not too bad, their is hoses on bottom and fuel lines to remove mark them so they don't get mix up- if you don't have a fuel bowl you might want to use jbweld on the inside bottom of bowl, it should last 1 year=tha5t way you don/t have to take it apart= bowls cost about 300 dollars around that price. if you get your jbweld at any autoparts store comes in two tubes per kit= sugjest you get two kits. make sure you remove the heater plate before you jbweld and use steel wool on bottom of the bowl or some wire brush in drill on bottom before you jbweld/ good luck.

i'll try to open it up and look into the fuel bowl tonight. i have some jbweld and have used it before, just never in contact with fuel. It sounds like the fuel heater may be causing the water/fuel to oxidize the aluminum. Thanks for the tip.
