Bought this 90 F-250 7.3 idi and this gauge was in it guy told me it's a rare and hard to find gauge but IDK many somebody can tell me what it worth and if there is a market for it it does work and all wires are there 2 standard wires the turbo line and the line that goes into exhaust included the diode that screws in

 

Probably more rare because of that strange line of text at the top that says "Made in USA" don't see that very often..

Hypermax lists the newer version for $228 so I don't know what yours is worth.

Westach sell dual gauges in that style, $305 for boost/pyro. I'd say that gauge is worth up to $75-$100. It needs restoration. Time is money and there are other options available for those that want dual gauges.



I have their boost+pyro, oil pressure+coolant temp, voltage mounted in a triple pod on the pillar and am very pleased with them. It was the only solution I could come up with to keep the important gauges easily visible at a glance and appearing clean and factory-ish.

 

Bigger question is, does the gauge still work? That'll impact the price

Just keep it commissioned, for the cool factor. Old truck, old gauge, "Made in USA", it's classic....
