Fuel pump or reg?
I know, ive asked this question before but i have new more clear info. (thanks for all of your patience with me) KOEO fuel pressure goes to 25 PSI and immediatley falls to 0PSI. A second try KOEO 25PSI, held for about 5 seconds then fell about 3 PSI, held, then fell to 0. KOER 30 psi, removed reg vacuum hose 40PSI. turned the car off and pressure went to 0 again. Would this be the pump or the regulator? I dont want to buy a new reg and then have to buy a pump or viceversa. Thanks again.
