It'* doing well. It fixed half my issues with the car, and got me 600 miles into CA all night last night. That'* where I am right now.

Idle is smoother, and it killed half my KR. I still have minor KR issues related to running lean at the top end, and there'* 5 different solutions I need to choose from.

ok, next Q. You think it might be possible that a working stock fuel pump might not be enough, specifically regarding KR?

Looks like it is working, I ran out to check my car and I'm at 42 psi with key on, 48-9 psi idling with vac line disconnected.

Bill did a lot of research, and in his application, the stock wasn't keeping up with his other mods.

However I think in 9/10 (aka mods that are not as extensive as Bill'*) a stock (assuming it'* functioning correctly) pump will do the job just fine.

Did the Walbro strainer hook up the same way to the fuel pump as the OEM? It looks a bit different. 3 people would have been nice to put in my gas tank. I was so drunk I don't remember even putting it in, but I did it by myself.

Glad to see that you got your fuel pump replaced and have fixed some of your problems.

Though, /me cringes at the spliced pump wires.

Sorry for the late replies. I was in CA all last week.

The fuel tank drop was slightly more difficult than most, but only due to the reduced ground clearance. Not too bad considering I was able to do it without help.

The Walbro inlet and strainer are a larger diameter, and just press on. Similar to the OEM, but they're not interchangeable. You must use the Walbro strainer with the Walbro pump.

Spliced wires in the tank are not a concern, considering all the contacts on the pump and strainer are exposed to and immersed in fuel anyway. Fuel does not conduct electricity.
