Man oh man. I'm finally going to be giving my car some overdue attention. I've had a hard start problem I've been failing to address for several years.

I am going to replace the accumulator, which I believe to be original, or at least super old. I may have multiple issues contributing to my hard starts, but the accumulator appears to be a major contributor. Also, the flexible hoses on the accumulator all appear to be trash. I've read several threads of some adventures and mishaps with this replacement job, and one common theme is that I should replace both flex lines now.

64449

Are these two hoses the right parts, and if so, is DMCH the best source? I already have a new accumulator in hand.

Yikes! The outer sheathing on that one hose has disintegrated away. You can just use standard fuel injector line like this: https://www.rockauto.com/en/moreinfo.php?pk=3861654&jsn=3

Another option, includes new clamps on each end.

Note it is the same hose and clamps for the two flexible lines up at the pump. Same hose, same clamps, same pressure rating, just different part numbers.

The high pressure rating is overkill for the relief line off the back of the accumulator as well as the return line up at the pump/tank. That line has very little pressure in it. It's easy enough to just put the same high pressure hose in all four spots though. And if you order them all at once, you'll get them thrown into the same bag so you won't know which one was meant to be which anyway. So there you go.

Love this. I like the hose clamp style that's included with those hoses too. I'll be ordering this today. Thanks!
