fuel dripping from injector pump

Gary Hunter · Apr 28, 2010

I have just bought a super Dexta tractor and when I had it running there was fuel coming from a pipe on the bottom of the injector pump. It was dripping pretty good and when I shut it off it continued to drip,not as much but still dripping and I was wondering if someone could help me find out what is wrong.I also noticed that the primer on the fuel pump doesn't work and didn't know if that could be the problem.Thanks for the help!

I'm not familiar with the Dexta, but I have a Simms pump on a Major with the same issue. The local pump shop had a look inside and told me the plunger-barrel assemblies are quite worn which allows the fuel to get past the plungers. Apparently this was normal even when the pumps were new, but to a much lesser degree, hence the drip tube. You may need to change the oil in the pump sump a bit more often to maintain adequate lubrication.
