I have a couple of questions concerning fuel filters. Basically I am
interested in preventing some very small rust particles from reaching
the carbs on my 76 TR6. The rust is originating in some of the metal
fuel lines. I have decided against replacing what I think is the main
culprit, namely the long metal line along the frame. All other lines are
replaced (thanks to all the help with bending lines and compression
fittings! - I sure learned a lot from that discussion).
I currently have a Fram G2 fuel filter ($4 at Walmart) which is a close
approximation of the original AC filter I'm sure. I have heard (can't
recall where( that the normal auto parts store filters are good for
particles down to ~70 microns in size. Is this correct?
In any event, it seems the particles which are getting through are
smaller than whatever the Fram screens out. I have a Truchoice catalog
which lists a nifty looking Earl's filter good down to 35 microns. Cost
is $30 US but the element (sintered bronze) can be cleaned and a
replacement, should it be needed, is $7 US.
A local speed shop claims to have a K&N filter good to 4 (that is indeed
four!) microns but the cost is $105 Canadian and I haven't seen it yet
so I can't say if it will be a good fit for my car (I don't really want
to get one of the larger racing type filters).
Anyone have any ideas on which filter (or another perhaps) would be the
best candidate for filtering out the really small particles (assuming
the Fram is indeed only good to 70 microns)?
Thanks in advance for any tips.
