How important is an after market fuel filter on a FI setup?

Like if i were to go with

Walbro Fuel Pump
Paxton FPR
AEM Fuel Rail

would it be worth it to toss the aem or other fuel filter on in there?

 

I was considering running an aftermarket fuel filter on my car. I've noticed a lot of people here run pretty good hp numbers and not have to run them though. It's an option since some are cleanable. I wouldn't say it's vital for say 300whp less. I would think it depends if you see your pressure drop off because of the filter being a restriction.

 

hmm helpful insight. thanks

 

I do recommend changing/replacing the fuel filter. Aged filters can cause a good pressure drop.

 

The only advantage of an aftermarket filter is the ability to just change the filter element with one from your local parts store rather than the whole piece from the dealer.

Which isnt a big deal when you figure that the OEM filter is like $25 or so, and shouldnt require changing TOO often.

 

As I see it the fittings to the filters and to the fuelrail is the restriction..

 

The fittings, lines and fuel rail are NOT a restriction till around the 550+whp level. The stock fuel filter is sufficient for more power than most of the people on this board would use.

 

so your saying that shooting for 300whp, and possible up to say 350whp to 400whp, the stock fuel rail, pump, fpr are more then sufficiant,

still recommended for upgrade tho right?
