The cowling over the stand pipe area, that provides fresh air to the engine compartment has no dorad, which seems to be the norm on T30s that I have seen.
Bill, when I got my T30, the blower was actually mounted just forward of the A4 down by the base of the mast with the ducting running inside the chase in the head where the original standpipe was located. When I changed from a waterlift back to a standpipe, there wasn't enough room in the chase for both so I went back to original ducting under the settee and out the back. The '77 model has two dorades, one in the head and one in the saloon. I have a day/night solar fan pulling air out of the chase over the standpipe that does a pretty good job of keeping moisture down. Since my blower exhausts into the cockpit, I know right away if fuel fumes are present.
