Hey guys, i have a 2004 lb7. It has an aftermarket lift pump in it already, but does not have a water seperator, do they make inline water seperators? I only ask because the lift pump works great and i figure i can just add a water seperator instead of buying a whole new lift pump kit. Also what brand of lift pump is this? Thanks

Most all major filter mfrs offer a filter head base, for $30-ish.
Baldwin FB1311 is one. Add to it the BF1212 FWS filter. There are others that use the same 1-14 Cat thread style.
You'll want to plumb the FWS in, before/on the draw side of the pump, having it pull fuel thru it.

It appears they plumbed in a small lawn mower gasser type of canister filter there.

Ok so where that small filter is, the fuel water serperator will be put in its that filters place after it is removed correct?

Also, do they make a base that i can use for 2 filters so i can have a regular filter with the water seperator? Thanks

What side is the filter on?
Needs to be on the intake side of the pump.

How do you tell? Follow the fuel lines, which one comes from the tank?
Which one goes forward to the engine?

Filter heads are singles.

Here are some ideas;

Yes it is on the intake side. And unfortunately i am unable to see any of the pictures from that link. With this base and filter you recommended, will that be able to mount to the pump, or will i have to make a mount myself?

Check it out on a PC?
I can't tell much from your pics as to what pump that is, how it's mounted, or where.

There is nothing high pressure on any of this stuff, it's all high volume/low pressure. So it doesn't take much more than hose barb fittings, clamps, and 1/2" bio-fuel compatible bulk fuel line to plumb in your own kit.
I'm not saying my kit is the only way to go, I just put that thread together for a reference of ideas on the basics for DIY design setup.

Filter head bases are either top mount or side mount fixtures. The Baldwin I mentioned is a top mount (common Cummins use). In the link (detailed with lots of pics) I used the Hastings KF-33 aux filter head base, which is a side mount. They also differ in where the inlet/outlets are placed.

Depending on where you mount the filter head, and where the pump is mounted, you'll have to create your own layout and fab your own bracket of some type to mount the heads. It doesn't have to all be jumbled up together in one tight spot, hose length used doesn't matter, as long as you have the order of flow as; FWS -> Lift Pump -> fine particulate secondary (if you choose to add one)

Read thru that link, it's mentioned how adding just the FWS/pump, changing the stock filter to a secondary (with a quality filter used) is a good mod too. I added the 3rd in the original design/concept, just because.
Testing after the fact shows I didn't really 'need' it, but it makes changing the filters easier down low and together. And if they both are doing as designed, the tertiary stock filter virtually never needs to be changed again (still testing on that theory).

Search the forum, many have done their own design, some top hang the filters, some side hang, some on inner side of the frame rails, others on the outer side of the frame.

Some are mounted to the shield wrap on the fuel tank, others use the shelf in place (unused for gasser emissions stuff) that hangs out on the front of the bed/cab area.

Let the creative juices flow. :wink2:

Take some pics and post back what you did/came up with.
May help others later on who are on the same quest.

With either the Racor PFF50216 or the acDelco TP3018, will have better filtration than the Cat filter specs do. And, they'll offer a backup for any water that gets past the FWS.

Ok, another question, with the baldwin 7633 fuel filter screw onto the FB1311 base ?

Tell me again what the ratings are on the racor and acdelco filters and why they are better? Cuz they have a water separator?

Yes. Any 1-14 thread filter will work.

Efficiency ratings.
4mic absolute @ 99.4 and 99.9%
Current ISO testing standards has the cat @ 4mic/98%.
The 2mic marketing claim is at a lower % rating...and based on old outdated testing standards and is not a true absolute rating.

Possibly.
I pay attention to the absolute ratings, as nominal means nothing IMO.
