Are plastic fuel filters really that bad?

[zf>allison]

He'd to go get my brother last night because his truck wouldn't start. Pumped his filter head pump and fuel gushed from the head and where the filter met it. Tried to tighten it and was already very tight. So it was suckling air, no lift pump. Switched to a microguard as no parts stores around here have ac delco now it's fine. And i had one wix plastic leak fuel as I have a fass.

The delco filter has been changed a few months ago to a tp3018 just FYI.... And I also will not use anything but Ac delco filters at a 15k interval I have changed hundreds of filters and have yet to have an issue with the gm filters

I heard a rumor the ACDelco filter is now down to 5 or 6 micron from 10. Either way the cat filter is great, I can get the 0750 for $9 each so I change them quote often, cheap insurance if you ask me

So why do you all THINK its better to change the filter more often? Because it isn't. The longer a filter is in service the more it loads up on particles and better it filter out finer particles. Up until the point it restricts flow decreasing power is when a filter is doing the best job possible at cleaning your fuel.

Rust isn't a problem its the water in the fuel that is the problem. I don't mind seeing rust in my filter. It means the filter is doing its job and catching the water before it trashes my injectors and pump.

I changed the filter this morning. I thought it was Napa Gold but it was actually Carquest brand. Back to OEM now. Thanks all.

I never change mine . Cat filters on the fass have 15ish thousand and the o.e. filter has over 20k

The cat is 2 micron, I would rather have a clean fresh filter then a partially clogged filter making my cp3 work harder.

Its not going to be working any harder until there is a significant pressure drop.

Well, you guys can keep running your high mileage filters. When you pick some bad fuel up and suck your filter down and rip it and let all the particles youv been letting collect into your fuel system, have fun replacing stuff. You may as well only change your oil filter every other oil change too.

I have a supply pressure gauge. Hasn't changed. 4psi @idle and about 1.5@ wot 0-100.

I blew a brand new plastic fuel filter out at the track one day on a 11.80's pass. Hot day+hot fuel on the manifold is not a good combo. It just blew the seal out.

Have you ever seen that happen? I only ask because I have seen stock trucks drive in, sometimes even towing trailers, that will suck a 12" vacuum gauge flat at idle. Trucks go into derate (except early lb7s) and those filters are never damaged. Come to think of it though i don't recall a plastic filter ever pulling high vacuum. Always o.e. style. If you've seen it on a Duramax I stand corrected and chalk that up to the now I know file.

At any rate, I am not concerned about a filter coming apart. Cat filters are tough and the o.e. filter is my last resort catch all. That's why I installed a fuel supply pressure gauge. When my pressure becomes low or erratic it's time to change filters. I am by no means picky with the fuel I put in my truck either. If there's no water or big pieces of shit in it down the hatch it goes. For 40k miles the filters have done what they do.
I do also go 10-12k miles between oil changes too

I change all 3 filter which two of them are 2 micron every time I change my oil which is usually no longer than 2k miles :roflmao:

I do the exact same thing, every 2k-2500mi. I do trans spin on with the oil and fuel filters also

I do the trans filter too. Grease the front while I'm under there as well

Lets just say I have pulled 30" and I have a liftpump... filter was fine... Another reason I don't get fuel from other peoples dragup tanks any longer and he had a filter on it.

That don't really prove much. Did you cut it apart and what kind of cheap filter was that? Fuel is pulled up through the center so as long as the pleats are still in place that filter didn't "fail" to badly.

I do my Cat filter at 20K and my stocker at 40K. I should be ok to go 30K and 60K, but I don't feel the need to go that far due to a possible lose of power.

I have no proof of this but I believe wix/napa/purolator and all other plastic filters are the same thing with different stickers

PUROLATOR switched over to the metal filters from RACOR now. Friend of mine told me about it about 6 months ago. He raised hell at ADVANCE because they were his parts supplier, and he had to have 3 trucks towed in within a month of each other because of there plastic filters sucking air. He said about 3 months later they switched to the metal filters. I also noticed O'reillys is selling the metal filters as well now under there brand, and CARFQUEST has went back to metal filters in there red line.

Couldn't have said it better myself, I will only install the factory A/C Delco filters on my trucks and customers trucks here in the shop.:thumb:

Mark, just curious I only run luber finer filters lff-6012 have you ever compared them the ac delco tp-3012 is rated at 98.6% effiencent @ 4 microns and the luber finer is rated at 99.4% effiencent @ 4 microns I've been running them since 2006 and I have to say the truck runs smoother and quieter the rating is better as well as the price difference at the dealership where I work the ac delco tp3012 is 50.00 and the luberfiner from a semi truck dealership up the road is 31.65 would you give me your opinion and views on this filter or try one for your self and tell me how you like it I also only run Baldwin filters on my Kennedy pump setup there again a local truckpro semi truck parts house filter is only 35.xx dollars rated at 3 microns thanks in advance mark take care and God bless
