I just spent a few hours researching the Purolator glass in-line fuel
filter subject, and was wondering if there was any recent news
regarding this subject. I perused several Matronics lists and found
pros and cons on the subject. I have then in my fuel lines down to the
header tank, and have been taxiing my plane with no problems so far. I
would like to install another after the header tank, which is behind
the seat, but before the auxiliary fuel pump. It seems that locally the
Purolators are no longer available, nor do they show up on Purolators
website, and everyone tries to sell me a Mr. Gasket look-alike, but
they are of VERY poor quality compared to the Purolator product. So,
can anybody shed some new light on this subject? I'd really like to see
what the filter is trapping, and don't like the idea of those cheap
plastic automotive filters.

Hi Lynn

After years of flying with the glass purolator just before the carbs, I got bored with seeing the same thing over and over. I considered the screwed together glass case to be a weak point and so now use a cheap STEEL automotive fuel filter. This filter is after the gascolator screen and is changed annually.

Remember, the more devices you have in line the more flow restrictions.

I have been using the NAPA version of the same filter -glass with a
nylon filter- just above the the header tank for 9 years with no
problems. I have done it two ways, one is above the seat so I can see
it, the other is just above the header tank and I cut 1 1/2 inch holes
in the seat back so I could pull the seat cushion back forward and see
them. I have see and heard of problems with using the paper inline type
filter. For some reason there is not always enough head pressure to push
the gas through them, especially at altitude.

Thanks, Jim-
Maybe I'll remove the glass filters a little later on, too, but for
now, after having re-Kreemed the tanks, I want to see what's flowing
down to the header tank. Just for the history of it, my 1994 IV is just
now coming together after being owned by three previous owners, and I'm
the first to get it past the "bare bones" stage. Therefore, the tanks
were virgins, and Frank Miller said last year that they should be
re-Kreemed, so I did that. So when the time came for the first splash
of gas, I really needed to satisfy myself that the system was clean,
hence the glass filters. I've always had good luck with them on
automotive installations in the past, then I began reading the archives
which revealed some folks having problems with them. Also, I don't have
a gascolator, using the header tank for that purpose, and taking my gas
sample from the bottom of that header tank. I ran a flow test and that
revealed 8.5 gals. per hour gravity at the fuel inlet to the Jabiru
fuel pump, so I'm well within the parameters for flow...way more than
that if I turn on the aux. pump. If I do install another filter (before
the aux. pump) it would be to catch anything that got by the header
tank.

Hi Lynn,

I have been uing the Purolater type glass filters since 1998 and like them.
It was by looking at the filter that I was able to confirm that the right
tank was sucked dry after a mis tightened fuel cap.

I am curious about the problems mentioned in the archives. Can you
elaborate a bit on what was mentioned. I have been on the list since about
1995 and don't remember anything that discouraged my use of them.

Thanks,

Lowell

Lowell-
My original search today came up with a thread of about Oct 27, 2004,
right about the time that I first came on board here. It was in
relation to the glass fuel filters, and you were one of the
participants.
I just got done with another search, and came up with the possible
reason that I haven't been able to find the Purolator fuel filters any
more. I'll reprint what I found under the Zenith-list at matronics
dated March 24, 2005:

Start of quote:

Very recently, I referred to a search for a Purolator "See Through" Fuel
Filter in a posting.
This filter was eventually located and found to be a *Purolator Pro-Fuel
Filter*. In the Google perusal
of articles on this filter, I found that *there is a recall of this
filter series* because the
polylmer used for the housing in the suspect fuel filters may not be
compatible with ethanol
and other chemicals sometimes found in fuel systems. If the housing
leaks, you could have
a fire. In another listed instance, an aircraft builder's filter leaked
and it was on negative pressure, sucked air
and his engine quit on takeoff due to fuel starvation. Subsequent
replacement of this item was found to
be difficult as the replacement product was re-marked as Made in USA and
it was obviously made in Taiwan.
The latter didn't even exhibit the necessary quality found on the failed
original filter made in the US.

So much for the Purolator Company and their filters. I didn't want to
have misled anyone into using this
filter on their plane just because the basic concept embodied what I'd
like to have found in one..........

Pleased to have found this, but immensely disappointed that the trend of
once good products are
disappearing and being re-mfg as similiar, but inferior items from
offshore that could get you killed.

Please be aware and *do not use the Purolator Part Numbers 804, 805, 806
and NAPA
624804, 624805 and 624806 part numbers*.

End of quote.

So you see, Lowell, this is what got me to worrying again today, and
also explains why I haven't been able to find the Purolator filters
that I like so much. I bought a Mr. Gasket filter, and it was
junk...very inferior glass tube body, with rough edges where it
contacts the rubber seals, really poor imitation of the filter that
Purolator made, and it incorporated plastic end-nipples that screwed
into the end caps, rather than the one-piece, barbed end caps of the
original design, and it was made in China...(not that there's anything
wrong with that : ) )

I did it for the sames reasons. Now that I've washed all the Kream out a couple of times there is nothing left to look at...so they have been removed.
