No pump needed on L5P, comes with in tank pump, stout one at that.

This VSE unit IMO is best since there is filtration AFTER the WIF sensor. Single filter L5P aftermarket units the WIF sensor is on the 'clean' side of the filter....if the water light comes on then it's too late. Stock filter has 2 sets of filter media in it, main one before the WIF and a secondary filter bit after the sensor.

Now, the durability if the stock filter....do a search of the troubles @blythkd1 had....pretty good reason to switch.

Great pics and write up. Those line clips really are a bugger. No way they'll be flexible enough to work when these trucks get old.

Powertrain or emissions would cover fuel system.

@JonM21Ltz , I think the filter minder will work fine with your VSE. The truck runs the lift pump to maintain 60psi.....it will ramp the pump up to help try to overcome a gelled filter for example. It's a hunch but, it likely knows how much the filters are used up by how hard it has to run the lift pump in a given situation.

Since your VSE doesn't really alter anything electronic, I think your filter readings will work.

Stock filter isn't a problem....until it is. Then it's expensive AF.

I haven't rushed to complete my solution, but totally get the folks installing the VSE. I'd use it if I hadn't put in a bigger fuel tank and used up all the space.

You can set alarms for any parameter in the iDash. I believe, fairly sure, you can set an alarm for a parameter even if you don't display it. I set one for oil pressure (full screen flashing) and am toying around with one for fuel rate as an economy coach.

Just a heads up, Donaldson only rates those bowls to 30psi. Twist drain is good to 90. Not sure why but noticed it in the catalog. I'll try and print it in here tomorrow.

I was close, 30 bowl, 100 with Twist drain. Don't know if it's the seals or what as those bowls seem pretty solid, yours obviously is okay seeing ~60psi......but that's the spec.

Attachment is from their current fuel filtration catalog.

Totally get you wanting to take it off...but it would be interesting to see if it held up. Guess it would be a pain though if it failed on ya on the road.

L5P Filter and housing see ~60psi while engine is running and the in tank pump keeps it there at all costs. Whatever psi you see on a readout, the filter hsg is seeing at least that, never less.

The pressure bump at startup is a programmed function designed to circulate extra fuel from the tank up into the engine and return back to the tank to help warm the fuel up. How long the extra bump runs is decided by the ECM based on temp and other factors. It doesn't always do it either.

Quality piece, and if you have doubts about the factory fuel filter this is the best replacement solution by far.

The VSE has another filter AFTER the water sensor (just like the OE has with the center bit). The single filter set ups have NOTHING after the sensor but your injection pump and injectors.
