I had gasoline odor in cabin of my '72 SIII E-type 2+2 so I started eliminating potential sources. My first was to remove the fuel pump and replace it with a cheap current pump. Didn't help the gasoline odor but performance picked up. I am thinking I want to go to a good Billet pump and be done with it.
Does anyone know the flow volume I need in a fuel pump. I know it is low pressure and think it is 4 - 5 gallons/ hour. Anyone out there know the answer?
As for the fuel odor....I am moving to the condensation tank above the fuel tank and the hoses in between. Any help on that?

Fuel pump/ fuel odor in cabin
Thanks all for your help.
Ended up doing all of it. The end result was the four tubes that come out of the condensation tank (above the fuel tank at the end of the world) were apparently original, very hard and loose on the barbed pipes at both the condensation tank and the fuel tank.
Since I could not get my fingers, much less my hand in there, I pulled the tank (fun, fun), replaced the gaskets on the fuel level indicator and repainted the areas where the paint was failing. Shiny and clean in there now though I hope no one will see it for years.
More fun times came when I got to stand on my head to reach the condensation tank (which I couldn't convince to come out) and cut the old tubing off the fittings.
The hose between the tank and the filler was good but I replaced it anyway since it was so very hard to go there (even more fun times and new curse words to describe the replacing event).
I ran the original fuel pump on the bench for a while and decided it needed a rebuild. Replaced it with what I now know to be a low volume pump that claims 30 gallons per hour at 4 psi. After everything was back together I went for a drive and discovered new horsepower that I didn't know she had. I guess the new pump will stay a while.
Thanks again, you all were helpful and correct in directing me to the issue(s). The odor is gone, power is up and life is good.

I had the same issue with my series II OTS and the problem was the hose going from the gas filler cap to the gas tank itself. Don't know if a series 3 has the same setup as a series II but it might be worth a look. Best, Pete

Replace the two gaskets on the top of the tank (fuel pick-up and float). Did the trick on our Series III 2+2. It doesn't take much to smell the gas.

The flow should be 30 gallons per hour. The pressure is not critical because it is regulated by the non-return valve, but would be considered to be low pressure by today's standards.

Might be 4 -5 lbs psi obviously I don't know.

Me again. I meant 4 - 5 gallons/ minute and the engine is the V-12.
Sorry for the error.
Great job - thanks for the update. Nice to know that's all out of the way!
