5-10 Micron Fuel Filters

[Roy]

So how long do these Earl type cleanable fuel filters last before they need a clean?

Currently running a Bosch motorsport 5 micron filter and about to replace it... Not sure it's worth paying twice the price for reusable ones as they look a ways smaller

You only need to change the throw away one 3 times before the reusable is the cheaper option

Not worried about the money as much as do i get to run one of these filters for 2 years stress free? Does their smaller physical size mean i need to clean them at shorther intervals...do some brands leak thru o-rings (or is that internet chatter BS?)

Mostly i cant find a 5 micron filter as the Bosch one i run is 5 micron and good for years.. I am guessing 10micron is fine given its all they seem to be offered in?!

I haven't had one leak on cars I've done work on, but if I pulled it apart I changed the o-ring while I was in there just to be on the safe side. We use to clean them every service just cause we could but it definitely wasn't essential to do so

I wouldn't waste your time with a skinny earls filter- too small, get clogged quickly, fuel seems to have to move to fast through them... I've have a couple and they just get thrown out.

I prefer a larger body with a bigger screen area, especially at such fine filtration. My injector manufacturer mandates 10mic.

I use Weldon filters in my GTR, big body- big screen area and very well made. Unlikely to come apart (compatible with meth, nitro meth and all race fuels)

Saying that, I'd just buy another couple of Bosch MS filters and be done with it... at least that way you don't have to change anything and you know they work.

It's likely I'll go that way with my gts-t build.

Cheers
