What does the thing do

Postby spencerdiesel » Sat Jan 02, 2016 6:28 pm

That plug that goes into the fuel filter base, what is it? My friend and I both have a small leak right at / beside that plug and don't know what caused it

You mean the bottom of the filter? That is the water drain / water in fuel (WiF) sender.

If looking straight at the filter from the driver side fender, attached to the filter housing just above the filter and slightly to the right is an electrical plug. Don't know what it does.

Mine and my friends truck both leak right there

Oh ok. What could cause a leak to appear there?

There is an O-ring on the top of the fuel pre-heater. Sometimes when you remove a stubborn filter it can loosen the stud holding the pre-heater...allowing fuel to leak. But be careful tightening it up...you can crank down too much and crack the pre-heater. But it could also just be a tired and worn out O-ring. They are a special square sided O-ring, and I believe you can buy new O-rings from Geno's Garage.

And while on the topic, why do people do fuel heater deletes?

Yes.

Because they're often too cheap to fix the thing. (IMO, of course).

I noticed my drain was leaking one day and went to my local case ih and picked up a dual fuel filter setup (off of a magnum tractor) works great for me. Uses an ff42000 and an fs1221.

As an FYI:

If you'll notice, the part numbers for those filter elements:
FF42000: FF = Fuel Filter
FS1221: FS = Fuel Separator.
