Yet another '84-'85 fuel pump weirdness thread. What I mean by that is the fuel pump won't run unless the trailing coil is something something. It's a relay that turns the fuel pump off for safety reasons.

You'd have to see the other forum to understand. It seems to pop up there like once a week.
Got the Walbro in place where the old pump was...now for fittings and new hoses. All the hoses under there are exhibiting dry-rot!

With the Haltech, am I going to need anything else to make the pump work?

Can I not just get the fittings I need for this pump to hook up to what's already there?
Would it be worth it to run new fuel lines?

pump to suck through. The GSL-SE pick up is much larger.
The existing steel lines running to the engine compartment are probably ok -
if you want to upgrade, just run a new 3/8" line to the front and use the old
feed line as the return.
You also need to run new wires to the pump - the stock wiring harness isn't up
to the job. I've even had problems powering a 6 psi pump for a carb. Use about
12 gauge or so from the battery (fused) to a relay (haltech may have provided one)
to the pump. Also don't use the harness ground wire - it's no good either. Just
run a wire from the pump ground to a conventient chassis bolt.
