I set up my "bean Counter"
designed system based on the articles in Passagemaker magazine. I used two
Racor 500 filters in parallel followed by the pump. I put a lot of valves that
allow me put either use one or both filters online and to use the pump to transfer
fuel between tanks and or polish the fuel. When filling the filters I turn on
the pump and divert the output back to the tanks. Once the filters are filled I
change the valve to direct the output to the engine and start her up. Based on
Captain Wil's advice I purchased a vaccuum gauge to install after the filters
and before the pump, but this won't go in until the spring snice I was
considering where to locate the gauge face. I also have to install the optional
"water" alarms, on the Racor's, but again I didn't determine where
the alarm units should be mounted.
To make a long story short the pump is a
Jabsco Vane Puppy, model 45710‑000. I chose it cause I was trying to do
the same thing you are and this was the only one in my catalog selection that
seemed to fit the bill. By the way it is rated for continuous duty so I can use
it for the longer polishing times like Captain Wil speaks of and it has a
bronze pump body and a Vectra rotor. In reading some of Captain Wil's posts I
don't think he used this pump. It even sounded like his pump was less
expensive. The one I purchased is listed on page 435 of the West Marine Catalog
at $173.99 but I got it thru M & E Marine Supply Company for $149.95.
I have never considered it as a back up
"fuel pump". I did not know my engine had a separate fuel pump other
than what they refer to as the lift pump and the Fuel Injection pump. It is a
Perkins 4‑107 if anyone wants to comment on this.

There is an article on page 28 of the fall
1996 issue titled "Fuel System Management" which got my interest. On
page 23 of the same issue is a picture of the system used on Traveller which is
what I started to duplicate. The are also some other photos similar to this,
like page 21 in the premier issue. But when you see most setups they use the
dual 1000 unit's, which I think you can purchase like that. The 500's are
plenty big for my system so I had to design my own. I have two tanks and
wanted to be able to run either filter or
both and I also wanted to be able to transfer fuel or polish fuel.
Unfortunately, until we attended our first Trawler Fest I didn't see the real
thing our system was
completed and Captain Wil had confirmed the
concept of polishing could work for us.
In the spring I will take a photo of the
system and put it on our web page but a sketch will have to do for now. I am
separately e‑mailing you an attachment that contains the drawing I used
to design my system. I will forward it to anyone else interested. I can snail
mail it to you if you can't read the file.

Subject: Diesel Fuel Pump
In your discourse regarding the F‑1
filter, you referred to a fuel pump which was used intermittenly during your
cruising. Apparently, this pump has a
flow‑through capability when it is not running, enabling you to use it at
will on a push‑comes‑to‑shove basis without restricing normal
flow when it is off. I have been looking for a pump in 12V with those
characteristics.
I have written Stewart Warner about one of
their pumps, but have received no reply. I am in the process of reworking all
of my fuel lines and revamping filters, etc. A pump placed in the same position
as yours to use for bleeding, priming filters, etc, and not necessarily used to
feed the engine except in emergencies really appeals to me.
One question comes to mind, however. Most
electrical pumps come with the caution of preceding it with a filter to uphold
waranty and keep from clogging. You apparently don't adhere to this (i.e, we
also have an electric fuel pump between all of the filters and the tank.) Have
there been any problems of this nature?
Will you be so kind as to identify your
electrical fuel pump by name, model, etc., so that I may look into purchasing
same for my 34' 1979 Mainship.

Hi Terry
The pump I use can be bought at any auto
parts store for about
$20 and can be installed after the filter so
it will be running on clean fuel.

General Diesel Pump Issues
WALBRO PUMP SOURCES
Pump No. 6802. Max capacity 60 gph.
Company Engineering Number (517) 872‑2131
Purchase Source : Peterson (800) 262‑8799
NON‑POLISHING SYSTEM PUMP OPERATION
The pump can normally be used to prime all
filters in the system to which it is connected. Normally, the engine lift pump
will allow fuel to flow through it and the injection pump will bypass any fuel
it doesn't need. If your system is like that, the Walbro will pump air until
fuel replaces the air and then pump fuel. If the engine isn't running, the
injection pump will bypass all the fuel and air back to the tank pumped by the
Walbro. When all the air is gone, your system is primed.
POLISHING PUMP OPERATION
When installed in a polishing system, the
pump will be down‑stream from all the filters except the primary on the
engines itself.
It may be used successfully to prime all the
filters in the system except for the primary filter on the engine. Just put the
valve in the polishing position. That will draw air from the piping and fuel
from the tank, through the filters and return it to the fuel tank.
My pump is installed in this configuration.
After I installed the Gulf Coast Filter F‑1 diesel filter, the Walbro
primed the whole system in about ten minutes. The F‑1 holds about two
gallons of air. After the filter and piping was primed, the engine started and
ran normally.
