Your pictures are great. It looks just like my fuel pump. The picture of the Precision M20021 on the oreillyauto.com web site is very different at first glance. I realized my mistake. The Precision photo shows the underside of the filter. Daaaaah. I will order it for my 305e. Thanks for bearing with my quick observation mistake.
Question: Is there any position the pump’s cam area has to be in when you remove and replace it? Can I just pull it out and stick the new one back in? Does it go in guided or do I have to be precise when sticking the cam arm back in? Sorry - so many questions:-(
