Remove MFI stacks
 

I have a 70E and am trying to remove the MFI stacks so I can remove the engine shroud. I have done some searching but cannot find anything that describes the tools needed to get to the nuts that hold the stacks. On the outside nuts I can just get a 12mm open end wrench on there is no space to get a ratchet at least as far as I can tell. What I can't seem to figure out is how to get to the ones that are in back, toward the center of the engine. Between the stack and the shroud there does not seem to be enough room to get any type of wrench.

Any suggestions would be great. The engine is in the car but looking at the space I can't see how it would be any easier even if the engine was out.

I haven't done it on that engine, but Sears makes a set of deep offset closed head wrenches that worked with mine. I also bought a set of Craftsman swivel heads that fit on my 1/4" ratchet with a couple of extensions. They are pretty low profile so they could fit in there pretty good.

Yes sir......1/4 drive swivels should work well. At least the Snap-On style does for me.

Thanks, The 1/4 ratchet swivel did the trick.

Now that I have them off what is the best way to clean the stacks or shold they be sent out? I am also going to be removing the pump and I guess would need the same advice for that.

That is easy if you have the stacks off. Remove the six metal fuel lines and get them out of the way. Remove fuel inlet and return line and oil inlet and return lines. Loosen four mounting nuts and slide pump enough to remove the timing belt from the front pump pulley. Remove the electric connections and thermostat line as well as the throttle linkage. Finish removing the mount nuts and lift it out. It is full of oil and gas. Are you going for a rebuild or just cleaning and replacing? Pumps are not servicable by the avarage mechanic. Requires special equipment and knowledge. Search this site for storage methods or rebuilders. Check with Henry, Gus Pfister, or Mat Blast for rebuilding and there are a few others, I think.

BTDT.
