Restoring !ate Grandparents 1958 Oldsmobile 98 4 door sedan
Hi everyone. I obtained this car when my Grandmother passed away over 35 years ago. If has been in storage for that long. I have a brother- in- law that is a mechanic who is helping me with the restoration. We were hoping to have it running within 2 weeks but as you know one thing lead to another and another. We are now in 3rd week and not even close. I will post pics when I have some. I am learning slot and have already got info from from this group.

Well it’s been a year and we finally got car back together; however we are having issues with fuel system. Starts up and idles for awhile. Drive about 2 miles to start break in. On return stopped getting fuel to carb. We have checked everything. Even put on electric pump in case fuel pump was bad. Ran great for short time and stopped getting fuel. Any ideas would be appreciated. We are stumped.

If this car sat around for 35 years, all sorts of crud may have accumulated in the tank.
Best to remove and clean it toughly.
Also, any rubber hoses in the system may have collapsed internally. They should be replaced.

We checked all lines and fuel tank. Today ran great until got hot. We determined we were getting vapor lock when engine gets warm. Gas we were using was winter blend with low boiling point. I thing we are going to have to put in fuel injection system. Thanks for all the ideas.

WHOA! Why would you want to do that ?
Installing fuel injection in these cars is a lot of trouble and expense.
In the first place, winter blend gasoline will cause vapor lock in warm weather. Get rid of it and get fresh gas . 91 octane or better.
Are the hoses in the fuel system new? Old hoses will cause you grief.
Have you checked the fuel pump with a pressure gauge? A good pump will put out 5 PSI.
I think you will be a lot better off fixing the fuel system properly, and saving the $2500 or so and spending it on other things . JMO

I believe it something else, not vapor lock. AS a cheap test string(cover) all the gas lines with a pool noddle to insulate them from heat, see if it doesn't do the same thing again, I bet it will. A fuel pump that is on its last legs will often run well at first, but when pushed will fail because it can't keep up the volume needed to run the engine. Lots of ways to test a fuel pump or fuel pump issues without spending big bucks.... Tedd
