Author Topic:   Rochester fuel gage for 1982 Outrage 18

I know there have been threads on this before, so I apologize for adding to it. When I bought my 1982 18-Outrage, the fuel gauge was missing. Through the threads on CW, I found the proper gage (I think)- Rochester-dial #5-1792.

I put it in place, seems too small for the space, very loose, and won't match with both holes for screw down.
Also needle stays at roughly 2 o'clock postion either way I put it in.
I added 5 gallons of fuel, and no change to needle.

Do I have right Rochester gage?, or is the float bulb stuck?

Hi Stefan, when you purchased the gauge, did you buy the jr. or the sr. gauge? The sr. is the proper gauge. You can verify this by going to the e-components website and looking at the schematic diagram/drawing. In the drawing, measurements show the distance between screw holes both diagonally and from one hole to the adjacent hole. If you compare those measurements to those on your boat, the size will be confirmed.

you were right, they sent me the JR size, instead of SR, so I ordered SR, but not sure if that will solve problem, may need to see if float arm stuck .
will let you know what happens

thanks again.

fuel gauge arrived- CORRECT # is 5-062B(B=Brass)
fits perfectly, so ignore CW post that said dial # was
5-1792 (at least for classic 18'outrage)

needle set at 3:00 postion either way I put it in, so either it's 1/2 full, or beyond full.

needle is at same postion as smaller gauge, and when more fuel was added, no change in needle.

I'll add more fuel over the weekend see if it changes, if not, then I'll have to see if float arm stuck.

At its very best, the fuel gauge in those tanks is approximate. It takes awhile to get used to what the dial is really telling you. It is consistent, which is its most useful feature. Once you do get used to it, you will know what it means.

The first thing you need to know is the gauge will be almost useless unless the boat is level. If it is sloped one way or the other it will over-read if the tank is anything more than half full.

On my Outrage 18 the gauge would be pegged at Full anytime the tank got more than 3/4 full even if the tank was adjusted to dead level. It would thus take a long time for the needle to come off the peg.

But it was very accurate in the lower ranges. I never ran that boat dry. Ever.

Try your gauge with the fuel tank well below half a tank and see if it does not respond.

Having said that, I will say that I have seen cork floats become totally waterlogged (fuellogged?) and need replacement. Not a difficult task at all.

thanks for info. how do I know when fuel is below 1/2 tank, if I don't know needle works?
can you stick a marker down into fuel tank?

If I were you I would just drain off the fuel from the tank and then see how the gauge performs. If the fuel is not pre-mixed with oil, fill your car or truck up a few times and that should get you below half full no matter where you are now.

I tried to respond earlier but posted in wrong spot...
I had same problem w/ gauge and found it was because needle took quickest route around the dial. Tough to explain but if you play w/ dial putting it onto the assembly and rotating it you should be able to get it to read accurately.
Also ensure the gauge is clean as a minor build up of salt / corrosion was all that was wrong w/ mine to begin with. (Before I broke it). Play w/ it.
