i own a 04 rx8. lately occasionally i give it gas and it wont go. 77000 miles. fuel pump seems to make a noise of and on when this happens. so i turn off car for a minute then it will drive fine. used to do it more only when the low fuel light came on now it can happen anytime. can it be fuel pump? and where can i buy a fuel pump . they dont look bad to install. just dont have the tool to remover the big ring.

 

Try these guys below fast shipping and cheaper than some competitor, I just got a Walbro pump for my 93 and it works awesome.
