Thanks to the info here on the idi forums, i have chucked the old 1g alt and the mechanical lift pump into the nearest dumpster. Im not a mechanic but combining these two swaps was pretty straightforward. The thing that was tough was cranking out the air in the stock return lines, had to recharge the 4 yr old batts 2 or 3 times. But the new alt keeps them above 12 volts. One question tho: how does the wif sensor ground to my wix fuel filter? PO had it on the old alt -post.
