Help me pick a D1

Brad, that's all just preventive maintenance never had to replace the vacuum advance?

Truer words were never said! Nope, vacuum advance is in tact for now. Of course since you brought it up I better go order a replacement!

Also, as the fuel pump goes, it overloads and melts the contacts in the fuel pump wiring harness, which causes a loose connection causing it to cut out or stumble, even after fitting a new fuel pump.

On my '96 DI, the (2-3 feet long) connection from the fuel pump to the main harness had a plug/connector going bad (at the fuel pump side) and the fuel pump would cut out for seconds (or minutes) at a time. Was "fun" to diagnose and I was -that- close from replacing the pump (i.e. "fuel pump out of the truck, new one on hand....") when I realized that the connector looked pretty bad. REplace the connector/extension/whatever that small wire is called and re-install original fuel pump. Still going strong now (4+ year).

Exactly. I think a lot of fuel pumps are replaced without replacing the plug/wiring and the problem carries on down the line. It's easy to diagnose this by running power direct to the pump, bypassing the harness completely. The fuel pump relay can malfunction too, though I've never had one fail myself.

Honestly, fuel pump problems are the only thing that has ever left me stranded beside the road since I started driving Rovers.

Got stranded in a friends d1 on a logging road in BC an hour from civilization and no cell service and needed to catch both the ferry and then a plane back to Toronto. It was the connector at the fuel pump and I got it going and made all my connections. This area gets a lot of dirt, road salt, etc and it's good preventive maintenance to pull the cover off and clean it out once a year.
