[TR] gage question

[Rye Livingston]

Dave,

As I’m putting my rebuilt engine back in my 1960 TR3A, I’m also installing all new AutoMeter gauges, and the oil pressure gauge will be electric.  I’m also adding oil temperature and volt gauges, so I have 6 gauges. Greg Solo in Santa Cruz who races a TR4 and I think he services Baby Doll, the blue Morgan that races in vintage, he’s made a bolt and banjo fitting that is along the oil journal downstream from the oil filter and oil pressure adjustment, believing it’s a more accurate source of oil pressure measurement being downstream.



I bought the fitting and the metal pipe which is pre bent to the correct shape with a tab that attaches to one of the bolts on the fuel pump threads which you can see in this photo, even though I’ve blocked off that spot and am running a Hardi electric fuel pump.

Also in this photo I temporarily hooked up the original oil line to the original gauge just to check oil pressure when I started the engine for the first time and had 70 lbs.



This is the transition. The left side in the photo is the old oil line pipe which I’m not using but has the same female fitting so I’ve included it for this photo.  Next is an adaptor to go into that female fitting, then two brass male slip fittings.  That hose is rated for oil up to 300 PSI, then to the electric sending unit.  I went with a 12” hose so the electric sending unit will be under the dash away from the heat.  Not that I really needed to do that, but why not.
