Stainless fuel filter cleaning

Recommended Posts

Since switching to E85 a couple years ago I have been running stainless fuel filters.  The 100 micron is easy to tell if it is clean.  The 10 micron is tough.  How are you guys cleaning stainless filters.  Ultra sonic, hand cleaning with a solvent, blow out with compressed air, ???

I've never used E85, but I do have a 100 micron prefilter. I've always just sprayed solvent through it from the backside until it looked clean. I'm sure if I used an ultrasonic cleaner with the filter sitting upright so the crud could fall out of the opening, it would come out even cleaner. 

ETA I also have a 10 micron, but those are (paper? fiber?) and I just replace those whenever I see a slight drop in fuel pressure.

Ethanol base fuels will eat and degrade the paper filter.

I run E85 and a microglass 10 micron fuel filter. I swap it out every other trip. Fuel filters are cheap, engines are expensive. Also, I don't have a 100 micron pre-filter because I have the Holley Hydramat so it's not necessary.

Throw the 10 micron stainless away and replace each season with micro glass. Done. https://aeromotiveinc.com/product/10-micron-microglass-replacement-element/

What is wrong with the stainless 10?

I will have to check if Kinsler injection has micro glass filters for for their housings.  
 

i have a ultra sonic cleaner that I am going to try with the stainless filters.

I called Aeromotive at some point a few years ago. You simply can't get it clean enough.

Small ultrasonic jewelry cleaner will work just fine. We have a large industrial one that works great.

I bought a 6 liter ultrasonic cleaner and solution off Amazon.  It worked really well.  Filters look brand new and got a good amount of debris out.

One thing to know about these ultrasonic cleaners. They can be dangerous. 

Do not stare into them while they are on and do not put your fingers or hand into them while they are running.

They will destroy the bones in your fingers.

What type of solvent did you use to clean the filters?

Well that is scary.  Good thing I didn’t put anything in there while it was running

Kinsler paper element I just replace it.  I use SS prefilter but with the hydramat I don’t think it will be needed.
