Testing Pressure

After noticing a minor fuel leak on our 1971 Jensen FF MKII, classic car technician John replaced the fuel pipe and clips. This stopped the leak and resolved the issue.

However, when John started the car, the oil pressure gauge showed low pressure. After speaking with the owner of the car, it was confirmed that the gauge normally displays a pressure of around 60 psi. John wanted to know if the issue was a faulty pressure gauge or if there was a bigger issue causing a drop in pressure.

The oil filter was removed and John ran a test using a gauge that he knew was working correctly. Without the oil filter fitted, the gauge showed 50 psi. After John put the oil filter back in and ran the test again, the working gauge again displayed 50 psi.

This was enough to tell John that the gauge in the car was the issue rather than a more serious issue which was the best outcome in this situation.

Work continues on our 1971 Jensen FF MKII and it won’t be too much longer before it is returned to its owner to enjoy again.
