My 78 has had what I thought was a noisy main pump since I?ve had it. Recently it started having a noticeable drop in power, so I figured it was time to do pumps. (The car came to me 2 years ago half put together with 2 el cheapo pumps) I figured the in tank died and was killing/killed my main. Well, I was half right, the in trunk fuse had popped, but the pump was still alive. I had them so I replaced them anyway with a fresh sending unit. Started up, and she sounds the same. Confirmed power at both pumps. The noise is louder towards the bulkhead than rear floor, but too noisy with the hood open to isolate. It I put my hand on the filter and lines, I can feel the vibration more strongly then on the main pump. Does the accumulator act as a dampener? I?m not sure where to look next.
