66 lemans...fuel pump question

Jun 04, 2006 11 Replies

I have a 66 pontiac lemans. I just removed the gas tank so that I can work on replacing the trunk pans (rotted through in areas).



Well, now I need to be able to move the car in and out of the garage. I can hookup a small gas can using gravity to feed the carb for this purpose. The question I have is will I damage the mechanical fuel pump by running the car without fuel running through the pump??



Should I be considering anything else? Any info is appreciated. Thanks.



It will not be damaged. Its just a diaphram and 2 valves. No expensive motor to burn out.

Your point is a good one, however, I must quibble with your conversion from feet to PSI. Unless I'm mistaken it would take a little more than three feet of gasoline head to equal one PSI.

It should work because the gas is sucked out of the bowl. Hanging a can on the hood is how we used to run carb cleaner through the system. Gas ~0.28 psi/ft.

WHOOPS! You are absolutely right! When I typed it I got my formula backwards! Believe it or not I use that calculation every day in my job, sizing pumps and valves for industrial companies.

That's OK, Keith. You are forgiven. Thank goodness the rest of us NEVER make a mistake like that ;-)

Thanks to all for the replies. The pump is an original type mechanical pump. I will try the gravity feed first, and if that does not work, I will hook up my remote gas can to the pump (I only need to be able to move it in and out of the garage periodically.

Just pay a little kid a dollar to sit on the radiator and spray starting fluid into the carb for as long as you need the car to run.

JUST KIDDING!!!!! PLEASE DO NOT REALLY DO THIS!!!!

When you dropped the tank did you happen to find the build sheet. I have read that its a common place to find it on 66s.

I didn't find a build sheet....of course I was preoccupied with trying to keep 40 years worth of dirt and road grime from falling in my face!

But seriously, no build sheet was found when I dr> When you dropped the tank did you happen to find the build sheet. I have
