I've had two and one of them I installed myself. I really like them but just never seem to justify to put them on my boat now. Granted I wish I had the money to do it. I think it can really show you alot of information "live".
The install I did on my MACK E9 included all the pressure snubbers and sensors. I think I added something like 8 or 10 fuel connections which made me think about doing it again.
I have had friends that could never get them to work on certain installations, they went back and forth to no avail. These people were professionals too, so I have heard of that too. Some people put alot of money changing all their fuel lines out, full flow fittings etc to them, to get them to work. Its not a simple plug and play, although you can get lucky.
Chet they work excellent. Plus a great company to deal with. Get the basic unit in the photo it is all you need with a mechanical motor. Get a piece of jacketed 8 lead wire from Freeport Marine. It makes for a neat install. You need to wire two senders one on the return & one on the feed side. Once calibrated you are done. I did nit myself not a hard job.
I have to say just quoted one out at $1100 or so for the 5500 series. That I think would pay for itself with fuel at $4/gallon. Why do I think I paid $2000 or so for the 5500 series for a Mack E9 back in 2002.
Larry, did you have to put in those snubbers/dampers in yours? I know on my MACK install they told me I had too. Looks like for the Cummins I dont have too.
I doubt it has changed but by DIP switches on the back... It can be a pain in the ass doing, but actually I think I lucked out and got in the ball park with my MACK, I didnt do the install on my first one, so not sure what was done...
I know on the MACK E9, 900HP, showed how ugly it got at about 22knots...
Yes I needed those damper cans. See photo attached in the upper right corner. Just a little more plumbing. Calibration was not hard. It was done in 2001 and have not been touched since then. Make sure when you mount the display that you can get to the back of the gauge easily. The instructions gives you a very close pin adjustment. The one thing that will drive the gauge wacky is any air leaking in. Our diesels will run with minor air leaks just fine. It can go without notice. But the flo scan will not adjust with even a minor leak. If you see very small air bubbles in you Racor when under load that is an easy indicator of air.
