replacement fuel gages

Post by akholland »

Does anyone know of a boat fuel sender and gauge that will fit in the tank? maybe off eBay...? or a replacement guage that will work with the maule senders ? I have a pile of 8 senders here and a few work but none match the gages from the factory dash cluster. the best I can get is a half full reading from my tip tanks senders in the m5 wings . I think I need a 30-230 ohm...
Guess I'll go rob some gages out of the junk boats out back and play with it some more.

Are you sure the float arm is bent such that the slipper gets full travel on the winding.
Low wing old Pipers use same sender but arm needs adjustment

Sometimes the windings are worn through and it is hard to see, so the slipper connection only works on a portion of the travel.

it did this with multiple senders. Did maule ever have more than one ohm range for their guages? I know the gages in my 63 model are different but they are individual guages. I'm curious if all the m4 and m5 guages that are part of the 3 Guage cluster are the same ohm range. and what exactly that ohm range is supposed to be.... this particular m4 is a 64 model I think

In the 60's AC made the gage and senders, in the 70's Stewart Warner made them, in the 90’s Rochester made the and now UMA is making them, and none of them work with each other.

we have ours sent off and overhauled/rebuilt. If interested I can try to get the name of the company that does this.

Got it fixed for less than 10 bucks! Sight Gages!!

Step 1. Grind off the old broken sender from the steel circular plate and drill a hole in it and install a AN 1/8" aluminum tubing fitting. Stub a tube out.

Step 2. Install a Brass T inline with the forward fuel tank supply line.

Step 3. Rob the visual sight gauge system from a wrecked super cub. There's diameter reducers in the clear line to keep the level from sloshing. Making sure NO sags in line that would give false level and that the bottom elevation is no lower than the tank fitting in level flight.

Step 4. Add measured amounts of fuel and mark flight levels and on ground levels.

Step 5. Never worry about a failed guage EVER AGAIN! and enjoy the increased accuracy and SAFETY!

Debated using the rear tank supply line, but decided against it as the forward would represent empty before the rear would. What do you think?

For this to work accurately you need fitting bottom middle of tank and another a top middle of tank. If I remember right, isn't the sender access about half way up tank side? So in level flight, you indicate a full tank when over 1/2 tank in tank? Not exactly legal either?

not legal for certified use I'm sure but it's experimental.
but it's about 7/8 or better up the side. more concerned with the accuracy of empty. I'm pretty sure 43.13 says only empty has to be accurate anyways.

To signal empty, you have to have a fitting at BOTTOM of tank and halfway back to front.
