That vacuum spring in a double action fuel pump is so strong that it makes getting the pump back on the engine hard. What's a good method to fit the pump to the block? I'm talking about a '49 straight 8.

It sounds like you need to buy a shop manual for this car.:rolleyes:

Find a couple extra long bolts of the same thread size. Start them in, then push the pump flush with the gasket pack. One at a time put the correct bolts back in. Essentially the same way you would install the transmission/bellhousing to the block.

Also, keep in mind that the position of your camshaft can make this harder to install. Try rotating your engine by hand to see if it improves while you're installing the pump.

Exactly. If the cam lobe that drives the fuel pump is up, rotate engine 180 degress or so. The pump should go in w/ minimal effort. Make sure you have the correct gasket stack and you should be good to go.

I'm on my 2nd one in 5000 mi and the air pump crapped out 2 yrs ago. I'm back to a simple single one which I can replace diaphragm's in m'self. If I hit a hill in the rain, I just let up for a wipe or shift down. The late 8s and big 6s take the same pump by the way.

Is anyone using a rambler pump with a spacer ?? If so where can you buy a spacer.Would not be too hard to make just ought to be a cheap item if avaliable ?

You can use the AMC pump with a spacer. The stock pump should have used a spacer.

Thanks for the tips on Fuel Pump Installation. Getting the cam lobe out of the way and using guide studs helped alot. I think that by putting the right hand bolt in first might have streamlined things. And next time I'll take off the wheel to make access better.

thanks Again.

Marker, I hope you reused the gasket stack that was on the original pump. If not don't run the car as you will break the new pump.

Speaking of "guide" bolts - here's a tip for installing cylinder heads that use bolts that I'm sure somebody has already used.

Get 4 long bolts the right thread size. Cut off the heads. When installing the cylinder head put one bolt in each corner, then lower the head down over the bolts. Start a few cylinder head bolts, then remove the 4 guide bolts.

I took a hacksaw and sawed grooves in the tops of the guide bolts I made so I could take them out with a screwdriver.
