Matt, If there is a crimp in the return line somewhere that will create a higher pressure back from it and the car will have trouble running. The accumulator does have a moving diaphragm, but not enough to normally make a noise. I would look for return blockage or something like that. Call if I can help John Hervey www.specialtauto.com 972-564-9321 -----Original Message----- From: denverdelorean [mailto:denverdelorean@xxxxxxxxx] Sent: Monday, February 21, 2005 9:59 PM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] Fuel Accumulator Can the fuel accumulator make noise? I just replaced the fuel pump because it failed but now I am having similar symptoms again. I pulled the pump and ran it out of the tank but the noise seems to be coming from the transmission tunnel area. the pump seemed fine. The car emits a high pitched groan that seems to strain to pull fuel. It just started out of nowhere. I didn't think the accumulator had any moving parts. so where could the noise be coming from? The car also sputters and stalls like it is out of gas unless I keep the revs really high.(thats how i limped home) Matt To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
