I'm pretty sure I need to replace my fuel filter as I've seen some fuel dripping from it, but my question is that I noticed fuel puddled on top of my filter housing, could that just be from my filter and being pushed up there by air, or something?
Also I did my return lines and "O" rings and noticed that they run from the passenger side front twards the rear, crosses over to a fitting on my return line, out the other side into the rear drivers side injector to the front, and ended at the from cylinder. The metal return line that connected the rear injectors on both sides ran to the front and connected to the top of the injection pump. All the schematics I've seen show the line jumping from the right rear injector over to the left rear injector to the front and then into the injection pump. So I added a brass "T" coming off my front left injector joining that metal return line and then to the injection pump. Does that sound right?

 

Sounds like your fuel heater is leaking fuel out

 

I deleted the under hood fuel/water seperator and now I am running a Bio- glass 5 micron filter instead .... it has solve manny issues for me and the truck .... as I was continually have issues with filters and the housing .....

 

So is the fuel heater needed in Sacramento region? We rarely see freezing temps overnight in the winter, and is the heater housed in the top of the water/filter housing?

 

it is not a fuel heater ... its a water indicator for the fuel/water seperator ... dont worry about it .. those filters will pass water either way ... just change the filters with oil change .. I do mine @ 10K along with oil .. and I buy fuel in only a few select places to minimize bad fuel possibilitys..
