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.

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.
