Well first off the motor hasn't been starting very well and the primer bulb dosen't stay hard like it used to, so I decided to start with replacing the bulb and fuel line. <br /><br />The factory OMC primer bulb I am replacing has part # 328492 on it and no one around me has one in stock but one place sold me a 5/16 OMC one part # 174511 and said it should work as a replacement.<br /><br />Could someone check primer bulb part # 328492 for me and see if it is a 5/16 bulb? I thought it was a 3/8 bulb but the guy said since it was a factory bulb on it now it was probaly 5/16.<br /><br />The motor is a 1999 Johnson 90 hp model J90PLEE<br /><br />THANKS
