The pressure is almost inconsequental in operation. The hoses probably just rot with time and heat exposure.

Yes it was a little vega station wagon that had the low oil engine cutoff circuit. I found it by accident pulling out of my driveway. The sudden left hand turn killed the engine when the oil was a little low.

That car by the way had a notorious reputation for burning oil. Mine seemed to miss that particular difficulty and was still reasonably good when I scrapped it. The floor from the front edge of the front footwells to the hatch seemed to have dissapeared though.

I actually considered the chevette a step up from the vega back then.. To make matters worse the station wagon was the gt model. One memorial bump possibly left a headprint in the roof panel. All I remember was it really hurt and the bump in the road was not that bad.
