Leaky fuel pump

[Ryan123]

Hey guys My fuel pump on my 1970 am gen m35A2 seems to have a small leak (nothing major) just enough to kind of be annoying.

I haven't tore into it yet just wondering if there is anyone on here that has. It's probably just a shot o-ring i would assume?

any input is greatly appreciated

Picture?

i dont have a picture but it looks like its coming from where the throttle cable goes into the pump itself.

Have you downloaded and read the TM's ?

 

[Ryan123]

not yet that was on my list i was just wondering if someone knew what it was because it seems to be on just about every duece ive seen

You mean, injection pump?

 

[Ryan123]

Yes sorry injection pump right under the air comp.

Check out TM 9-2910-226-34 for the injection pump. It will give you a good working understanding of how the pump works and where the seals and "O" rings are located on the different assemblies. If it is coming from the fuel shutoff rod assembly I would think it is most likely from a bad “O” ring on the fuel control lever assembly or a bad cover gasket.

If oil is coming out yes. If fuel is coming out then its either the fuel control rod o ring or one of the HH o rings leaking.
