I didn't say it was cheap...

And just so it's clear, a return line must be used with it I believe.
 
Correct. For me I think its a waste of $$$. Reason is if the EFI pump quits then you are out another $100+ and you have to buy fittings to adapt to the existing feel and return lines which are about $20 each then AN fittings, hose, and more AN Fittings. All in I would say you will be in the $600 range to do this. For that kind of $$$ I would just get a pickup for the tank like this:


Then get the size of fuel lines that you want to run so that would depend on how much hp you are trying to make. I would say AN8 for the feed and 6AN for the return but you might be able to get by with 6AN on both and you will need fittings. Good place to get Teflon lined hose and fittings:


The you will need a filter, regulator, and pump. Depending on what you buy and how you shop you might get out of it for around the same money as retrofitting the EFI system for a carb and you will have a better fuel system.

I do not believe you can unless you switch to a standard rotation water pump as the covers are different. If you go this route you will need a ribbed water pump pulley and I think ASP makes one but you would have to call them.

 
Yes . Best idea is to cut only the red wire and loom tape it right at the tank . Then your gas gauge still works. Install a marine fuel pickup and run a 5/16 fuel line to thhe engine bay and run a electrc pump to the carb . Be advised that in wreck you will have to turn off the ingnition or it could pump fuel to enggine
