Great information--especially about the pictures of the senders/trasnducers. THe Floscan lit makes them look much larger than your actual pictures.

I thought they had told me you couldn't get the dual display gauge if you were running Floscan on EFI engines with a return line to the fuel tank. Is that not part of your fules system?

fuel return lines are found mostly on diesels. FloScan has conquered that now also, from what I understand.

They are available. I have the 525 EFI's, stock. I'm connected at the senders from the tank to the sender (In) and from the sender to the low pressure side of the fuel pump. (out) It was a B*%^h getting those brackets mounted! As well as getting the fuel lines back on.All I have left to do is connect the port/starboard ignition wires and rest switch. Then a little tidying up with tie wraps.

I've looked at adding the FloScan to my engines--they are MarinePower EFI 454's with the Arizona Speed EFI system. MarinePower's fuel system has the lines that return unused fuel from the rails back to the tank. I knew Floscan had modified the diesel system for this sort of application but I thought they said you were restricted to the single disply--the dual display wasn't compatible with the duel sender config. I son't have enough real estate on dash for two more big guages -- that's why I' really interested.

Call 'em direct. They are very receptive to questions and such. I now understand your dilemma.

I installed a set last year. Very straight forward. Like it has been mentioned it will take a couple tanks to get them dialed in. I interfaced mine with the GPS. Gives me real time MPG. I should not have done that. I knew it was bad but I thought it was much better than .75 Nautical MPG!
Oh well it's just money.

Using a Flow Scan you can slightly change your crusie RPM, and trim settings to get the best fuel economy possible.

Troutly,
That's what prompted me to install one. I felt it would give me the ideal trim settings at cruising speeds. It can also show if an engine one engine starts to run bad compared to the other. It was less than $500.00. I could probably recoup that this summer in fuel savings. (Maybe)

The other thing I forget to mention is that it will give you a very accurate reading of fuel in the tank vs. guessing. It should be accurate within 2%. I have gone across the southern part of Lake Michigan from Benton Harbor to Chicago, and it would have been nice to know on a couple of occasions for a little extra piece of mind.

I personally like to see the analog gauges. I have never seen the Smartcraft, but I wonder if you have to page through to see different functions or if you can monitor multiple one's at the same time. There's probably + and - to each. Personally though I like analog. Have you seen the digital one's?
