Gas pressure goes bye bye.

So after drilling my primary plates last night I was read to test her out.

Well, I started her up in teh garage and she ran.....in the driveway she ran.

I noticed that my fuel pressure gauge was reading like 1 psi.

Ok, now its a $18.00 deal from Pep Boys and first thing I thought was "stinking gauge went bad!" because the car was running....never looked at the see thru gas filter.....well, the car ran and made it about 5 miles away to my kids daycare.......on the way home from daycare, right as I pulled onto a major highway (of course) it dies.....wait a bit and eventually it runs enough (almost no idle) to get into a parking lot......

I find the fuel filter is running itself dry. Shut her down and gravity lets some gas back into the filter......

Does vapor lock do this ? I dont think so but ...maybe?

I ran home with the gas cap off but barely running....

...all that would be left is either the regulator is bad or blocked (brand new, installed yesterday), or the fuel pump is taking a crap, right? Couple days ago it was pumping 6.6 and 7 psi....hence the regulator...now the guage is reading 1 psi when its running......after shutting it down, the pressure creeps up a bit.....

Once the engine cools down I will remove the regulator and see if that changes anything.....

Glad I was only a few miles from home............:angry7:
 
Well, my issue seems to be simpler than yours.....

I removed the regulator and hooked everything back up...pressure is back at 7 psi.

So bad regulator. Far as I can tell.

What makes a regulator fail!?!?!

On top of that I figured my gas mileage to be a whopping 6.4 mpg.

Of course, thats a lot of idling, testing and running poorly.....as well as one drain of the carb and a couple of the lines in the engine bay.
 
did it look like this. these things are garbage, they go bad all the time.

That's true. Back in the 80s and 90s I didn't have problems like I'm having now. I had a big block too with cramp room in the engine bay with headers and stock radiator. I think that stupid ethanol has a lot to do with it.
