I recently tried installing a fuel pump I purchased rebuilt but it seems the the arm that goes inside the engine is too long, am I doing something wrong?

Hi Gunny,

I, of course, haven't seen your pump, but I can hazard a guess as to why you are asking. The first thing is make sure you have the right pump. If you can't figure it out by looking in the manual, post a pic here. I'm sure someone will be able to positively ID it.

I've found that the pump can be a bit of a bear to get in. You can't just put it up against the block. I thought that I had the wrong pump when I first tried it, too. First, I'd make sure that the cam lobe isn't in a position to be actuating the arm, i.e. you don't want it pointing at the pump mounting hole in the block. Then, in order to get that actuating arm spring to compress, you have to get the pump as close to the block as you can, then start the bolts. Using the proper mounting bolts helps this process quite a bit, as that spring is pretty stiff. Now you can draw the pump up tight to the block using the bolts.

Good luck...

I've never seen a mechanical fuel pump that was easy to install. Overcoming the spring tension on the actuator arm while trying to line up the bolt holes with one greasy hand and install the bolts with the other greasy hand in a confined space can be (and often is) a real b!tch. When you get it in there and snugged down, though, it's good to hear the engine run while you do the "Miller time" thing!

Rebuild from T&N

as for trouble in the confined space, remove the passenger side fender and accouterments. Makes it a lot easier to get in there.

A kit or something of the sort to rebuild the pump without that vacuum pump thing. I suppose it's off a WC or something. Anyway, Sid sent me the parts to convert mine and I am a hell of a lot happier without that vacuum pump on there. Mine leaked oil from the day I brought it home...
