Fuel leaKS lift pump & filter housing

OK so the guy I bought my 12 valve from for some reason put a holly blue on it.Why idk.What I do know is I hate them.I replaced one over the end of summer& it's leaking from weep hole again.So my question is how do I go back to the stock manual pump?
Also my fuel filter housing has been leaking for awhile which I can only imagine could damage the engine if I don't fix it soon.I cannot seem to find where the thing it leaking from Even though it pools up on the cover so I was going to go to Geno's garage & order a pretty 96 housing.What all will I need?Any help would be greatly appreciated.All of a sudden the past 2 months this truck has given me more problems then I would have ever thought.I have a 9500k check on the way which I can throw about half into the truck but don't want to.As it's not everyday my broke **** gets that kind of a check&I have other plans.Anyways any help would greatly be appreciated.Thanks...Also when I start truck when cold if I give it some go pedal I get white smoke.Which I'm guessing &am hoping is normal with what all is going on.

I can't be positive but it sounds as if you may need have a head gasket starting to leak or possibly a cracked head. Just went through that with my 94.
Another possibility may be the banjo bolt on the top inside of the injector pump, it has a spring detent inside that maintains back pressure on your fuel system

the white smoke I figured put was just because of the cold,just got to figure out the fuel leak.What would make you think head/headgasket?

The white smoke can indicate a head or head gasket problem as can the banjo bolt not holding enough back pressure in the fuel system. Does your truck start easily or do you find that it is a little difficult after it sets for several days?

Your fuel leak could be the bonded metal washer gasket under the fuel lines. That is hard to comment on without seeing it.
