Can any one tell me if a push pump will help my stock 7060 at the pulls we farm with the tractor and the injection pump is turned up all the way and it just seems it needs more fuel

Probably not, unless you have a blockage problem of some sort. I've run DM-4 Roosa pumps like that at approx. 325 HP for pulling and never had a pusher pump of any kind. It won't hurt but, it may not (probably not) make any difference.

Their is a lot more to turning a DM4 pump up, than screwing the leaf screws down, the roller shoes, need to shorter for 1 thing. Your pump probably has a delivery valve stop leaking. That will leak the fuel back in the pump that should be going to the injectors. Take it off & let a pump shop help you out. GOOD LUCK

We run one on our 7050. Back when it was about new and it was pulling 6 bottoms every fall, grandpa said that it did help it out some.

Big Orange can you explain more on the delivery valve leaking? Ive got a 180 that seems the fuel bleeds back and takes forever to get it started/smokeing, what needs replacing?

So if a delivery valve is bleading off it will be hard to start right? My 7060 is not hart to start

Im just guessing here ; but seems a delivery valve would leak back keeping the fuel to deliver to the injectors as fast

That's what I would but there talking bout it bleading off and I would think stuck ones would be hard to start or many no start

A leaking delivery valve stop is an internal leak. It isn't that they lose prime with it leaking, it just doesn't deliver the required fuel. The delivery valve stop is basically the "cap" at the end of the high pressure passage in the rotor. A pump can be turned up slightly with a little know how, but it takes a lot of know how, and a complete teardown to really crank one up.
