Another fuel pump question

Have searched to forums and the net. Can't find a good solution.

I want to polish fuel using my 2 racor filters, and add a gulf coast F-1 filter.
I need at least 100 gph. Can be 110v or 12v.

My choices so far

Groco SP0-80-R ~$500 USD
Reverso GP-602 AC Metering Gear Pump ~1100 USD
Reverso GP-602 DC ~ 500 USD
Reverso GP-302 DC ~380
The 602 allows for adjusting flow rate to match filter size.
all are reversable.
The reverso does't have a indication on their site that these are continous duty pumps, or about ignition protection. I will call monday.
Groco is a name I know, Reverso is new to me.

Any one have a comment on this ? Thanks.

I think one of these might be sufficient for your needs fairly cheaply. Your choice AC or DC.

Several of the professional fuel polishing folks I have talked to recommend the Tuthill.

How many hundreds of gallons of fuel do you need to polish?

I own a commercial fuel polishing bussiness and I have a top of the line fuel polishing machine, there is no comparison to my machine and a make shift one. However, running a make shift one for hours on end does your fuel good periodically, especially if you can do it while your underway. While your boat is rocking, it is sloshing the fuel and suspending the contamination enabling the contamination to be filtered out at a greater degree then just your filter before the engine. You would have to put fittings on your tanks to be able to do that.

will have a total of 130 gal.
split into 3 tanks, main is 70-75 gal. and two 30 gal tanks.
2 will be new alluminum tanks (the 30's)
the 70 is being pulled asap, once I have the 2 30's to transfer the 60 gal i have now into. Once I pull it, I will see if it is salvagable, or needs to be replaced. tank is 25 years old, deep in the bilge, on a boat that is noted for bad fuel tanks . (Endeavour)

My plan is for one fill, to the 70 gal, and use the 30 gal tanks for polishing, and transfer. Used to be water tank there, but I will have 100 gal of water, and a water maker, so that will be suficent.

Trying to get the main systems in place now.

Thanks for advice.
Bob

Nice pumps and cheap, but not rated for continous duty, not ignition protected, or marineized, and not sure if this would be the rigt choice for a permanet setup.
They would work well for fuel transfer though.

Holley Performance Products 140 GPH "Black" Electric Fuel Pump*12-815-1
Not designed or recommended for use with fuel injection systems

Used for autos. A upgraded pump from what I googled.

What are you opinions for using nonmarine parts in marine service ?
My thought is its not a good idea. There is a big difference between marine service, and land or auto.

I know there are a lot of marine fuel polishing kits out there, for a ton of money, but since I have dual racors anyway, I think adding a f1 filter, and a heavy duty continous rated pump, I should be able to do a pretty good job of it, with new tanks.
I don't want to high a flow rate. The F-1 filter is rated for 2 gpm, but want the option to add a additional filter, hence the adjustable flow idea.

Model F-1

I refuse to answer that question because it attempts to establish Liability.
I recommend you use a marine certified unit if your unsure.

Bob, on Holley's website they list the "Black" pump as marine. They don't mention Diesel as a recommended fuel though. Would you hook this up to also allow for use as an electric bleed pump too? If anyone out the owns a "FilterBoss" or similar unit, would you know what type of pump they use? Thanks, Chris

I have the Reverso 302 gear pump hooked to a Racor 1000 as a fuel polishing system. I spoke at length with Reverso tech and they assured me this pump is for continuous duty. In contrast, they told me that their OP-6 pump could also be used for diesel transfer or polishing, but it was not rated for continuous duty. Reverso sells a dedicated fuel polishing system that uses their 302 gear pump. The pump works very well for me - gives the rated flow and no problem running it for hours at a time. One problem with a lot of the automotive pumps is that their flow decreases significantly with head pressure. I don't know if the Holly has that issue.

Walbro makes some of the best continuous duty pumps of all sizes. That is what we have just bought to set up our polishing system.

I have not been able to find a walbro pump in over 100 gph size. what pump did you buy chuck ?

According to a ocean navagator article on fuel polishing, at least 100 gph is recomended.

I think I am going with the reverso product line.
Thanks colemj for the review of it.
