Advice needed on changing fueltank senders.

Hi, I have a '74 Trojan Tricabin with original senders in the tanks.

I re-did my dashboard with new Teleflex gauges. The senders don't mate up, reads 1/2 tank at full, and then does weird things from there on out (like goes backwards towards F, etc...).

The Teleflex senders seem cheap enough, but how much of a PITA is it to switch them out?

Any issues pulling them out? (they are directly under the salon floor.) Hoping I don't have to cut the floor to replace them.

Any advice would be appreciated! (Like do the holes line up? Any tricks or tips? etc....)

P.S. They're 77g galvy tanks, if that makes a difference....

Is the boat in storage now? If so remove the old sender and compare with the new. You likely have an inspection hatch above them or with any luck can get access alongside the tanks. Hopefully a Tricabin user can give you specific answers.
I would not expect the flange hole layout to be the same.... things have changed too much over those 35 yrs.
Once you have the old and new gauges it should be quite easy to make a transition plate to support the new bolt hole layout and cut gaskets to suit.

Hi

Just noticed your post from this past January regarding fuel tank sender units.
I too own a '74 Tricabin. In the floor of the galley cupboard, to the right side under the sink, there is an inspection hatch just above the fuel tank.

I'm not sure about the starboard side fuel tank, but I believe it might be accessed through that hinged riser, built into the steps leading from the aft cabin to salon that swings up to allow access to the front of the fuel tank?

Thanks
