If not their must be a distinctive difference in appearance between the two??

We just had one go out and the other mechanic in a different location coverted it over to the 2cyl pump.

Since it was changed out after 2-3 weeks ago the truck still stumbles whenever it wants to, cuts off for a sec then the driver has throttle again.

Light comes on fuel rail pressure codes. Could we have bigger issues with this truck???

I know for a fact all he did was convert it over to the 2cyl style.
He didnt do anything else or what some of you are stating needs to be done

Sounds like the same problem I had last couple of weeks. You probably have air in the fuel system... you need to find it asap before truck starts to shut down and harder to start.
