Fuel Sender
 

Guys,

I know fuel senders in boats can be horribly inaccurate. My port fuel level sender is way "happy" compared to my starboard. So, I just use the starboard as my indicator to get som go-juice.

However, is there anything I can do to remedy the existing part. Or, do I need to buy a new sender?

Thanks,
Zack

Don't they have a calibration screw on top? At least to get them in line with each other, not make them accurate.

To be honest, haven't even looked. Just one of the small items on my "to do" list for this yr. Will be getting it out of storage in next couple of weeks and do some more investigation. Just thought maybe I would do some research and be ahead of the curve...

By they way, where are the access ports in a 35' Founatin to the fuel senders?

Can't answer that one. My 27 and 32 both have the access covers in the rear bench seat storage.

The simple answer is yes there are much more accurate fuel tank senders. The one in your tanks is probably the old mechanical type with a float on the end of an arm which moves a rheostat and sends a signal to the guage.

Newer ones are electronic, not mechanical. They use induction to induce a signal. They have a tube that has electronic circuits sealed inside. There is a donut shaped coil surrounding the tube that moves up and down and induces a signal whic is sent to your guage. They are less subject to sloshing and splashing and a lot more accurate. See the WEMA page http://www.wemausa.com/tank_sensors/...el_sensors.htm

There are others but most senders are made by WEMA

I am replacing my fuel gauge with a lowrance LMF-200 multifunction gauge this year. I'm hooking it up to a fuel flow sender and the existing fuel level sender with an adapter. The LMF-200 has an option for a 5 point calibration in the gauge to get it right. I plan to use that along with the fuel flow meter to try to get a good handle on my fuel situation, and improve my efficiency at cruise.

Any one know how long the sending unit should be for a 1998 fountain fever?:cool-smiley-027:

35 inches (Really 33) Sorry I couldnt resist LOL... I will measure one at the shop today and post it a little latter

1999 42 lightning
 

how about the length in a 99 42 lightning. That seems like a great inexpensive fix. Thanks Daryl

The 98 fever had a universal type in it the 99-35' has a part#7824 if it screws in, if it has 5 screws Its a universal type can be had at west marine. the 99-42' would be a #7825 or if it has screws the same as said above Hope this helps
