Default Fuel transfer/polishing pump

Steve,

Thanks for the pics of your system. Any suggestions on TP vs PT
filter?

Doug

IMHO the only benefit is that they soak up a lot of water. They probably

do
trap a lot of particles but also shed them.


That hasn't been my experience with them. My experience is that they do
not shed significantly (they haven't clogged the 2 micron Racor behind
them yet) and that they do trap a lot of particles. I guess they also
make good water separaters but I wouldn't know that since I've never had
a problem with water in my fuel even before I put on the GCF filters.

.... The Racor 2 micron filter that's past the
TP filters is now 2 years old and is still clean.


That's like bragging about how many times you can use the same condom.

You

lol, not quite. Otherwise, we'd be changing Racor elements every time
we start the engine. Unlike condoms, the Racor elements are safe to
keep using until they get dirty.

could have spent the same amount of money on filter elements instead of

the
TP filter system, and have cleaner fuel.


That also hasn't been anywhere near my experience.

A lot of boats have their primary fuel filter in a difficult location.
That's not an excuse to try and stretch the filter, it's a reason to

either
1- buy a different boat or 2- remake the system so that you can change

the
filter element easily & quickly.


My Racor is very easy to change. The engine mounted filter a little
less easy, but it's still only a 10 minute job. Changing either of them
required bleeding the fuel system though. With what I have now, I can
change either the GCF filter or the Racor and not get any air into the
engine. I can shut off fuel to the engine and bleed the part of the
system with those filters with the walbro pump. I can even change the
GCF filters and bypass them to keep the engine running if it's
necessary. I do have to shut off fuel to the engine to bleed them
properly, although filling them with fuel before putting the lid on
really helps there so if it was really an emergency, I could probably
keep the engine running.

BTW if you buy filter elements by the carton, you can carry a lot of them
and not pay much.


The main problem is that I had to change 2 of the Racor elements when
the engine died after operating only 20 minutes each. And with the
amount of crud in the tank, that trend was likely to continue for a long
time. That's totally unacceptable no matter how cheap you get the
elements (they're still expensive even by the case) or how many you
carry. The GCF 01-Jr filters before the Racor totally solved the
problem and cost me about the same as having the tank cleaned and the
fuel in it polished. Now, I have that accomplished and still have the
system installed for future use.

I know a lot of people here will tell you a lot of bad things about the
GCF PT or TP filters. But probably none of those people actually used
them to solve a specific problem. I have first hand experience and for
me, they're working great.
