Fuel Pump Catastrophe

[pvcar]

Well I had to get my brother to drive my Opel from El Paso Texas back to California, he made the trip back with only a few hot start problems which are common in my car. But then this last weekend he took it out and drove it Friday but when he went to park it he left the fuel pump switch on all night, well in the morning he gets in and goes to start it and the battery is dead and it had no gas, well what had happened was the fuel pump had run all night and had just enough pressure to continually pumped gas thru the Weber carburetor into the intake and into the engine and filled the engine from the bottom of the oil pan to the top of the valve cover. the only good thing was he didn't try to start it after he had checked the oil and noticed the gas in it. So he flushed the entire engine with clean oil and then put a new filter and some new oil in it and it started right on up. He got lucky I can say. Thats my story, and I'm stuck in Alabama with tornado warnings and no Opel.

There's a thread or two around here dedicated to electric fuel pumps. Lots of good info in there, some even beg our friends to wire it through a relay which will stop the pump if the ignition is shut off or the engine loses oil pressure. Safety stuff. Not that it would do any good in a tornado, though. I heard you should stay in a basement, or at least a storm cellar like Auntie Em and Toto did. Under an overpass is a bad idea, according to a TV show we watched the other night.
Anyway your engine is cleaner inside now. It probably wouldn't hurt to change the oil again soon.

If a safty relay is to much at the moment change the wire to/from the electric fuel pump to a contact that has a switched 12V so that if you forget to switch the electric fuel pump off, it will stop when you switch off the engine/ignition

time for a really good pressure regulator, like the Malpassi filter king. We have those.

Absolutely, positively do at least this.

I've played around with the idea of using a 555 timing chip to prime the carb.Say for 5-10 seconds.Then a three wire GM oil pressure cutout switch.
No oil pressure no fuel pump!!!!!
