Is there more than 1 port on an L6 engine for a temp sending unit? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm hoping to keep the temperature idiot light in the fuel gauge working after I install my tach gauge cluster....

If there isn't another port, has anyone tried this some other way?

There are a number of usable ports on both heads that can be used for sending units. If it is a pipe plug... you can use it.

It's an inline 6...and I haven't been able to find another obvious port...

Oh...sorry. I miss read your title. If not, I have seen Rad.hose slice thingies that the tuner crowd uses for extra temp senders. Look on Fleebay

I have a thermostat housing off a later 292 that has two outlets, on for the bypass and the other for whatever. Look around, they are out there.

On my 292, I have a thermostat housing that the parts guy at Pep Boys said was for a Toyota L6. [Old Landcruiser, maybe?] The OEM GM was aluminum, and one hot day while in South Tucson, getting my radiator repaired, I overtorqued the housing and it snapped. So off to Pep Boys, the closest FLAP. with the broken part. He didn't have the Chevy part in stock, so we size matched it with other Mfrs' parts and found the Toy unit. It worked and is still on there, maybe 15 years later. This one is cast iron.
Anyway it has a ~5/8" tap on the top for an input.

Sorry, I can't reconfigure the pic. They used to upload OK.

Some of trucks with 8V92s we work on have multiple sending units in one port. I'tll be a short straight pipe with a three port brass fitting.

We call it a tree and it isn't unusual to have temp, pressure, and a sending unit for a piece of test equipment out of the same hole in the block.
