Kevin;

My ’54 also dripped/squirted fuel onto the ‘gas door’ and subsequently all over the lower portion of the fender. When I bought the car it came fully optioned with an aluminum ‘tuna fish can’ over the gas cap, but I just knew cars didn’t need such nonsense so I ran the car for a while until I realized the wisdom of the TFC option. Tobs also had the same experience, and solved the issue with essentially the same method, that is, a means to direct the errant fuel away from the gas door and ultimately down to the ground. Perhaps Tobs can tell us if the third cap he had ‘on-order’ solved the problem.

I can’t believe back in the day all cars without baffles in the fuel tank leaked fuel on turns, but I guess before the environmental awareness anything is possible. I think HH56 has hit on the true cause in that the original fuel cap may have had a feature(s) that helped knock-down the fuel for the very short period of time required to be leak free. My cap, and one of Tobs’ caps appear to have the worst design possible . . . that is, a hole straight through.

My experience is the same as others in that the cap leaks when the tank is near full. Physics suggests a right turn, especially off-camber, would also be part of the equation, however anything that would initiate a ‘slosh’, like abrupt terrain change, would also create the possibility of a leak. So we may not be talking about a high-g right hand turn is the only case, since I can attest that since I’ve owned the ’54 it has not been used in anything that could be described as ‘high-g’!

I went back to page 59 of Tobs’ project blog and tried to open the attachment I included in post #581. I was unsuccessful downloading and viewing the PDF attachment. Seems the extension of the file has changed to PHP. I found that if I open the downloaded file with an Abobe reader application the file is still intact and is viewable. The process I used was to download the PHP file, after ‘right clicking’ the file select the ‘Open with’ option, and finally select the Abode application. Seems to work but I suspect the extension was altered somehow and should be reset to PDF on the server.
