Gasoline transfer pump

I have two 500 litre (120 gallon) gasoline fuel tanks on my new Power trimaran, one forward and one aft to aid in balancing the hull. However I am gaving a difficult time buying a fuel transfer pump. All I can find is fuel pumps for autos which are no larger than 100 litres (25 gallons) an hour and that is too small.
Has anyone got any ideas.?

How goes it Beau,

I was looking at using a Walbro pump

Walbro Fuel Pumps - Flexible Drive Agencies Pty. Ltd

local to us as well.

Got onto the Walbro pump from this article

Ariel - Cape Dory 36 - Projects - Fuel Schematics

And another of interest

Trawler World Features: Diesel Fuel Polishing System

these are Diesel, but i'm sure unleaded works in the Walbro as well.

I'm also sure I read an article from Bob Norson from the Coastal Passage, where he used a pump from a Suburu that he got from a wrecker.

I can't find the article so don't hold me to it.

Hope this help's

Dave

You probably won't find a pump for gasoline transfer

A pump rated for diesel is just that. Rated for diesel.

A customer of mine put a Walbro Diesel Fuel Pump on his gasoline powered vessel....the ethanol in the gasoline here "killed" it.

Depco Pump Company has a brand called Fill-rite it is the only gasoline transfer pump....it is designed for portable tanks

I work on fuel sites and the fill-rite is your best bet. They are rated for gasoline. They have a vaned impeller with fiber vanes. Anything that can make sparks or static is trouble. The pumps should also be grounded to the tanks. The flow of fuel can also create static.

Delmarrey...thanks for backing me up

Gasoline Transfer on a boat !

Sparks/static/grounds/miswired grounds/ bonding issues. Sheesh!!!!!

There is no way I would do this.......If I was that concerned about trim, I would look at moving potable water....not fuel.

Then again....fuel managment via a dipstick might be a good way to go...

I hate fuel gauges......

I'm a big fan of the magic stick as well for checking fuel level's.

I have to ask though, plenty of cars have electric fuel pump's, and the walbro pump's are sold to knob's with 500hp rice burner's playing doof doof music, who need to burn more fuel than the standard pump supplies.

Walbro fuel pump - Walbro Intank and Inline Pumps*

Those lil' pumps are usually a little diaphragm or fish tank pumps, not much to create a problem. But when you start moving lots of gasoline quickly, things become complicated.

First one has to deal with fumes. A recovery system maybe necessary under certain conditions.
Second the pumps have to be able to move the fuel without creating heat but usually kept cooled by the gasoline.
Third the seals and parts have to withstand 100% saturation 100% of the time. I can go on.........

But take a look at a tanker truck that delivers gasoline and see all the safety equipment that's aboard. I just had to work on one ours tonight. Fortunately it only carries bio-diesel. The upper management refuses to be responsible for a gas truck, thank you!

255lph isn't too bad for a sealed unit, though.

Holley makes several pumps for this application. These have flow rates greater than 60gph.

Thank you all for the help, I ended up buying a Walbro 320 liters/ hour which is about 9 US gallons/hour fuel pump for about USD$100.00.
I must admit I was surprised that there was not more choice in larger volume pumps at a reasonable price.

I must also admit I am surprised at all the paranoia out there in regard to gasoline on boats and from people who should know better. For christ's sake there are probably more gasoline boats on the water than diesel boats. As long as proper precautions are taken, as when refuelling, I do not see the problem.
This is an outboard powered boat, not an inboard.
You all drive gasoline powered autos?

No comparison!
On Cars the tank and motor are completely open from the bottom side with plenty of ventaltion. Boat are only open from the top side if the cover is pulled and usually closed in a confined space, with the exception of OB's. But I've seen picture where OB's blew their covers off, just as well.........................._/)
