Default mechanical fuel pump on a 95-99 crate motor

Im trying to install a mech fuel pump on my crate motor, it has everything machined out for the pump, but I tried to put the push rod in and it wont go in more than an inch, I looked inside the block and there seems to be some kind of sleeve inside the block, is this normal? is there an easy way to remove it?

Thats the push rod. is it stuck down, or can you pull it up? If it is down, the cam shaft has it that position, and you will have to "bump" the engine over till it is off the cam. Raise the rod up, and I use some bearing grease (little) on my finger to wipe across it to hold it up so I can install the pump. This isn't a fuel injected engine is it?

it's not the rod, it looks like a hollow sleeve. It was originally a FI engine but it is now carbed. It had a block off plate originally which I removed. Would there be a push rod in there if it was originally a FI engine?

also, the rod im trying to put in is one that I purchased from summit because I assumed there wouldnt be one in there.

If you're sure it isn't the push rod you will have to tear it partially down to replace it. I cannot believe it would have anything there if it was fi.

it seems to be a sleeve with an OD of 1/2" and an ID along the lines of 7/16"

I was able to insert a piece of stiff wire all the way in until it touched the cam.

anyone know the purpose of this sleeve and how to go about removing it?

I would assume it would removed the same way as the push rod. It probably is an oil tube for upper lubrication. Not needed with a reciprocating push rod? My perception.

You can however install an electric fuel pump.

too expensive to get a pump and regulator.... also, I know a few people who have run electric pumps and they never seem to work quite right.

I'm talking about an inline pump. I put one on my 82 1/2 ton years ago.

thats what I mean, even the inline pumps rated at 6-8psi seem to provide too much fuel without a regulator with a return line
