New Mechanical Fuel Pump..... Hummmm that looks different

Post by San Jose Steve » Tue Feb 19, 2019 11:51 am

I removed a leaky fuel pump this weekend. Upon inspecting my replacement pump, I noticed that it looks a little different. I'm sure it will bolt right up and pump fuel, but looking at its actuating arm, I'm wondering if I may be creating a headache for myself down the road. The arm is much thinner than the original. I'm wondering if this "slim" arm will put excessive wear on the shaft. Seems like the load will be concentrated on the "narrow" profile of the arm compared to the "wide" profile of the original. The wear on the arm of the original looks to be really minimal, just a little dark streak on the finish after 45K miles.

Did a quick search online but couldn't find a rebuild kit for my original pump so I think I'm married to this new design. I think it's a BCS brand Anyone ever have a problem? Thought I'd ask before I bolt it up..... I got 18 years out of my last pump. Hope to get the same from this one. Thanks, -Steve

I've had both types, never had an issue. Knock on wood.

Activating the pump does not take the same amt of force as a valve. So, if the aux shaft and lobe is of similar property to the cam, it should not be an issue.
