I’m not sure if this is an old topic or a new one or maybe I just need to search but is there a fuel filter out there that has increased flow or not are they all the same I installed the lift pump in mine and I was just wondering if they made a higher flow fuel filter for the stock filter housing

There are no high flow fuel filters.
And it’s not something you should want.

Most here want better filtration to keep the injection system healthy.
Something in the 2-5 micron range.

with your lift pump, even the finest filtration elements will flow far more than necessary for this engine, even under full throttle.

totally agree with posted reply
The lift pumps generally used are also rated at fairly low pressure around 4 psi though i am sure the flow volume is more than adequate .
Even if you assume a maximum fuel usage of say one gallon per mile at full throttle start and make the mile in 30 seconds which you won't that would be 2 gallon per minute flow .

When I roughly checked my fuel flow through original type filter and additional 2 micron filter it took about 7 seconds to fill a quart jar which would be equivalent of about 1.07 gallons per minute. That is just from a kennedy lift pump and did not include whatever aide the suction from CP3 fuel pump would provide.

So my conclusion is there is way more than enough fuel flow even through stock and add on 2 micron filter to fully supply wide open throttle.

However, if there is no lift pump or it isn't functional ( even with flow through lift pumps like the kennedy) I can also guarantee you won't get enough fuel to injectors for wide open throttle if you have 2 micron additional filter.

Guys and Gals: when talking about fuel flow in the CRD, do not make the mistake I did: I did not change the fuel filter separator until the flow was so poor that the car did not start. If you can believe it, not one of the Chrysler dealerships where I took the car for oil changes from the moment I bought it new in 2006 until now, made the change of the fuel separator and I was so stupid as to not read the precise recommended changes at 20.000 km as per the manual that came with the vehicle.
Finally, last month, it was done and the car has a pickup that it never had for many years. My mileage now: 156.000 km!!
Just in case I bought another cartridge on eBay for the next time, 20.000 km from now.
