olympic Posted April 1, 2018 Share Posted April 1, 2018 We sent Eddie's vacuum tank off to be rebuilt. It took 7 months but we finally got it back and it doesn't work properly. At first, we thought it was a leak at the Gascolator bowl because of the little bubbles but closer inspection revealed that the vacuum was not shutting off and fuel was still being drawn in from the gas tank. We contacted the rebuilder but he wanted to know what the engine vacuum measured. We did that yesterday and the 11A's reading was 16 inches of mercury. To be sure we measured vacuum on my 27 11B, it was the same. We have had all sorts of opinions from AACA members but I would like to hear from some Franklin members. I am guessing that the problem lies with the valve that shuts the vacuum off when the inner tank is full. We are getting gas into the windshield wiper hose and the vacuum line from the intake manifold. There shouldn't be any gas that high up in the vacuum tank. Any ideas?

Steve Braverman Posted April 2, 2018 Share Posted April 2, 2018 A vacuum tank is a very simple device. The upper chamber has a float and a snap valve. Either your float is stuck, the valve is leaking, or the rebuilder used springs that are too strong. Take off the top, and take a look. Link to comment Share on other sites More sharing options...
olympic Posted April 4, 2018 Author Share Posted April 4, 2018 Steve, the rebuilder has told us to ship the tank back to him and he'll figure out what the problem is. I hope it doesn't take 7 months. Dave Link to comment Share on other sites More sharing options...

amxny Posted June 1, 2018 Share Posted June 1, 2018 Make sure that your gas tank is vented or it will build pressure and push fuel to the vacuum tank. Link to comment Share on other sites More sharing options...
