Fuel Gauge/Sender Question

[daniel123]

Actually, he's trying that right now (my boat's at my electrician-buddy's place). Meanwhile, the question we have is, does the green sender wire need to go to the fuel filler ground AND the battery ground - or does it just need to go from the sender to the filler ground? Do all three need to be tied together -- the sender grounded to the battery AND the filler?

To quote a fellow member (BA),

"Ground is ground"

OK then,
You'll want to keep the fill bond wire (green) connected to a ground. Often that bond is attached to the tank bond (on a metal tank) and attached yet again to a metal (usually bronze) sea cock. They all end up to ground either at the negative battery post, a ground buss or maybe even to the engine ground so....

Green "sender" wire?
Your tank is poly, correct? No need for a tank dedicated bond (again green) but the sender does indeed need a ground. That could go to the battery post but in my case that ground wire (black) terminates at the ground buss up in the helm.

Photos.......please.

Problem solved: apparently it was the fuel gauge itself that was bad, for when we hooked it up, the new WEMA gauge worked fine -- if showing fuel levels a little lower than they really are. What threw us was the faulty gauge showing full when the key was turned, allowing us to think it was working and it was the sender or wiring of same that was bad.

The Osprey's fuel lines and filter are replaced and working as well; we think that the problem might have been an air leak at the manual shut-off valve at the tank, which when removed allowed for fuel to reach the primer ball and the engine.

Thanks for all the input, guys!

Congrats Dan!      I am glad you identified the resolved the problem as a working fuel gauge is not underrated!   I always tell myself that any project on my boat will never be easy and will always take twice as much time and three times the cost that is should normally be.  :sunny:  Good thing I love working on her and the guys here have been invaluable resource over the last year...  

PS - I use photobucket to upload pics.  It’s a free smart phone app that you can upload directly to from your phone.  When you want to imbed the pics all you have to do is copy and paste the IMG link which photobucket provides and you are done.. Just another way to skin that cat.

Calm seas and tight lines!

Congrats Dan!        I always tell myself that any project on my boat will never be easy and will always take three as much time and five times the cost that is should normally be.  :sunny:  Good thing I love working on her and the guys here have been invaluable resource over the last year...

Bob...

You crack me up!  I am an eternal optimist... what can I say!  :sunny:

BTW - My stock bait well / wash-down pump finally bit the dust yesterday when I was out fishing with my son..  Kinda glad it did - this weekend rather than next as I have several guys coming down for a weekend of offshore fishing...  Replacement (shureflo) ordered.  Found a decent deal online but I'm optimistic that the install will be smooth.  Well optimistic but not holding my breath..  haha..
