Does anyone know what the difference is between the 2.0 LSJ fuel filter (ACdelco #GF824) and the 2.2L/2.4L fuel Filter (ACdelco #GF821)?

I ask because Hastings makes a fuel filter (GF372) for the LSJ for $23, and it looks exactly like what I have on my car.

I've read the only difference is "the internally regulated fuel pressure."

I thought we had a fuel pressure regulator in the fuel rail or the tank to do that?

Can someone educate me please....................and yes...........I've searched and am confused by conflicting statments.

Thanks

 

hmmm. i would think that both filters would be identical...

i just got one from a friend who works at the dealer. 50 bucks.

 

The lsj's fuel filter is different then the 2.2's fuel filter .... the internal fuel pressure regulator is what makes them different.

 

Ok..........so is that the only mechanism the regulates the fuel pressure up to the injectors?

 

the autozone filter is the same for all three

 

The LSJ filter is designed to handle more GPH of fuel flow.

 

I gotcha. Since it's less restrictive than my stock filter, it wouldn't matter which one I used?

 

The last time I changed a fuel filter, I was in the er for 5 hrs. Hopefully it don't happen on the Balt

 

What happened?

 

the autozone filter blows. i have heard of alot of people that have had problems with them on the lsj. just buy the stock replacement filter. yeah its expensive, but you only have to change it every 25-30,000 miles so its really not that bad.

 

no problems with my autozone filter. but im not boosted or have high pressure fuel systems

 

hmm.. thats interesting, i just bought the autozone filter and ill be putting it on the car in another month.. ill keep you guys updated lol..

 

^ same here..just picked it up tonight, got the tool for it, will be going in this weekend

 

forgot to completely depressurize and gas got in mouth, nose, eyes... broke both lenses in my glasses. was sick as **** from the fumes b/c i was covered in gas for so long. my face was all burned for a couple days b/c gas is so harsh

 

Don't listen to the uneducated voices on this forum.

The AZ filter is FINE and is identical to the excessively marked up filter you can buy at the dealership.

 

I got mine in. Process wasnt too bad but its a messy one for sure. Replacing the fuel filter fixed the starting and hesitation problems.

 

haha, I'm far from uneducated, but you buy what you want .... it's your car not mine.

 

I bought the Hastings filter.

 

How much for the OEM filter?

 

i got mine for $30 at my dealership ....

 

i've been using the Autozone filter for 10k miles (or more), no problems.

 

exactly, i never had a problem with my old filter and i just changed my filter about a month ago and i've had the engine power reduced cel!!!! i guess it's because it fits all 3 cobalts, but the AZ filter does blow, i'm getting the ac delco right now!!!
