Sorry to ask the question that's been asked too many times already. What's the manufacturers name of the recommended fuel tank sending unit. Thanks.

Terry

Terry-If you have a sending unit in your tank that is presently non-functional, before you buy a new one check the grounding on the one that you have. If you DO have to get a new unit, if I am not mistaken the bases and screw configurations are standard. I found on my 20, just the removal and re install of it made it functional again. I'm sure Patrick or someone will come back with the exact specs. All the best for the New Year! Walter

Terry,

Isspro is the manufacturer that I always recommend... http://www.isspro.com/

Br,

Patrick

Thanks Captain Patrick. I'm on it. Tried another type today. Because of the float and the tanks baffles it's a no go.

Walter, thanks for the advise and salutation. Happy New Years to you and yours.

TRY WEMA THEY HAVE A FLOAT THAT GOES STRAIGHT UP AND DOWN

Capt. Patrick's suggestion are right on! I have three of them in 3 different tanks and they work great.

I got hooked up with Isspro looking for a good quality guage maker and have not been disapointed.

I turned Pat onto them and he liked them also.

I was tired of the cheap Teleflex, Faria and other crap on the market.

I always believed if your gonna put guages in, might as well use ones that read accuratly otherwise use idiot lights.

All my surveys over the years have showed just how far off the cheap crap guages are.

Bruce,
do you have the model # from isspro for the stock tank sending unit. I'm not sure on the length of the sending unit. Thanks and Happy New Years to all. Aloha

It should be a ISSPRO - RA9517-ISS UFS, 17" fuel sender STW MATCH, that one is for a 180 gal Bertram tank, fiberglass stock.

Anyone know which ISS model will work with the 230 gallon tank?

I put Wema's in the B25 and they've been great. Vertical orientation takes up less space...

Giff,

Pull your old sending unit out and measure the inside depth of your tank and the Isspro length should be 1/2" to 1" shorter than the depth of your tank.

giff i have the exact tank you have and i used isspro part # RA9521-XXX ,tube lenght 21" . built april 15,1973--231 gallon for oem.504 cummins diesels.

To all, thanks for your replys. I am on this. I orginally use the Faria unit that was supposed to be for the guages I bought *Had I known about ISS then, I propbabaly woul not have put in Faria guages*. I cut the lever arm so it would clear the baffles. Worked for about 1 day underway. This is the only thing that did not work right after my rewire job.

Bob sounds like your boat and mine were manufactured at close to the same time. Mine is a 1973, though I don't know the month. 231 gallon tank for a Cummmins 504 right out of the factory. Hull is 315-1297, could be that our boats are crib mates.

giff my boat is 315-1301 it stands to reason they were at least in the same yard together. both being 504 they probaly we build side by side mine was sold to a capt in mass.and had a bluefin tuna permit.all in the log with the boat.
