Is it possible to add a pressure gauge to a tire pump that has no pressure gauge? I was googling for pump hoses with built-in pressure gauge but couldn't find any. I was also looking for pressure gauges that can be attached to either end of the hose of the tire pump but found none.
You should be able to add one by adding a t-piece into the high-pressure line and adding a gauge to the T. I'd have hoped that someone would have made a ready-made one that wouldn't involve modifying the pump, but I can't find one, so I think you'd have to make your own.
On that basis, you'd need:
- a t-piece with the same internal diameter as your pump's air line
- another bit of hose with the same internal diameter
- a suitable gauge
Something like this Draper gauge with it's own flexible hose would provide both the latter two, so you'd just need a suitable t-piece (I'm not sure of the correct internal diameter, I'd guess 5 or 6 mm, but don't have anything to hand to measure)
