elementary Posted May 19, 2021 Share Posted May 19, 2021 How do I fit a new gauge to an old engine? Do I require copper pipe & fittings as well as a gauge? Quote Link to comment Share on other sites More sharing options...
RobPearce Posted May 19, 2021 Share Posted May 19, 2021 What you need depends on the type of gauge. Most viable cheap gauges are "mechanical" and require a capilliary pipe from a take-off on the oil light switch fitting. The gauge will probably be supplied with some flexible plastic pipe. It may also come with a fitting but probably not with a T-piece. There are electric pressure gauges available but in my experience the affordable ones are rubbish. If you decide to get one of them anyway, it will have a "sender unit" that screws in in place of the oil light switch. To have both, you will need a T-piece. The T-piece (and pipe fittings) obviously need to be the right thread. I don't recall what it is off the top of my head but it's fairly standard (certainly the same as a classic Mini so there's plenty of supply of the right parts).

Tim Bancroft Posted May 25, 2021 Share Posted May 25, 2021 Try LMA, brilliant company. I am sure a call to them would bring some assistance. https://www.lmaautoparts.co.uk/Motorsport/Gauges_Gauge_Fittings_Pipelines Quote Link to comment Share on other sites More sharing options...
