OEM Fuel Pump Replacement with After Market Pump
It was a breeze. I used an Airtex E8371 pump and a Carter STS-8 screen. Cost: around $70 for both.
There is a vent hose that connects to the stock pump. You will see it as soon as you lift the pump up. There is no clamp, just gently pry it off with a screw driver. (no pic of that..forgot the camera for the first 10 minutes)
Old Pump. (http://www.st-riders.net/aow/AOW%20-%20ST1100/Fuel%20Pump%20Replacement%20with%20Aftermarket%20-%20ST1100/Pic%201.jpg)
I made sure to leave plenty of wire to reconnect to if needed. The rubber sleeve needs to be reused. I found that rolling it off the old pump worked better than trying to stretch it off, less chance of tearing.
Stock Rubber Mount and the one that comes with the new pump. (http://www.st-riders.net/aow/AOW%20-%20ST1100/Fuel%20Pump%20Replacement%20with%20Aftermarket%20-%20ST1100/Pic%202.jpg)
You will need both.
Pump with both rubbers installed. (http://www.st-riders.net/aow/AOW%20-%20ST1100/Fuel%20Pump%20Replacement%20with%20Aftermarket%20-%20ST1100/Pic%203.jpg)
If you notice at the bottom edge the rubber has a rather large "notch" This goes on the bottom where the pump sits on the bracket. I reused the stock gas line because it was of a different type of matieral as the new stuff I bought, and I m guestimating the old line is meant for being immersed in fuel. I originally had the inlet and outlet of the pump towards the bottom to utilize more of the fuel, but I turned it so the connections were on top so I could use the old gas line.
Pump installed. (http://www.st-riders.net/aow/AOW%20-%20ST1100/Fuel%20Pump%20Replacement%20with%20Aftermarket%20-%20ST1100/Pic%204.jpg)
Make sure to get the positive wire(blue) to the + side of the pump. The pump came with crimp on connections,nuts and washers, which I used. I am allergic to the act of soldering.
Completed ready to install. (http://www.st-riders.net/aow/AOW%20-%20ST1100/Fuel%20Pump%20Replacement%20with%20Aftermarket%20-%20ST1100/Pic%205.jpg)
The nuts are 1/4" Like I mentioned before, I left the wires long, in case I want to reinstall the old pump.
I made sure it ran before bolting back in. After installation was complete, I jumped the pump again and let it squirt into a container. It seemed to have more pressure or volume than the old pump. I started it and let it idle, under the assumption that a leak will occur while idling,since it is using the least fuel. I didn't smell or see any leaks, but I was desensitized from the smell, so I will take it for a ride to-nite and report back.
Heres a link to the instructions I followed, it explains the vent hose I forgot to get a pic of.

All in all, a simple..hopefully permanent fix for the "hot fuel pump seizure syndrome"

Here's some more info if you shop at a part-number challenged place like Advance Auto Parts:
The E8371 pump has applications for:
HONDA ACCORD DX (1986 - 1989)
HONDA ACCORD LX (1986 - 1989)
HONDA PRELUDE 2.0 S (1988 - 1990)
The STS8 strainer has applications for a lot of GM, Honda, and Toyota vehicles, so I will include only those that use the same pump above:
HONDA ACCORD DX (1986 - 1989)
HONDA ACCORD LX (1986 - 1989)
HONDA PRELUDE 2.0 S (1988 - 1989)
You can use any of these as applications if asked.
Advance Auto does not carry Carter brand parts, but they do carry Bosch and Airtex, so I crossed over the STS8. The Airtex part # is FS9, Bosch is 68003.
The total shipped was $64.37 at Advance (for the Bosch filter & Airtex pump with a 15% discount on their site) or $64.74 shipped at Rock Auto (Carter filter & Airtex pump with a 5% discount code you can Google). The Rock Auto total dropped to $55.66 by using the Airtex filter (lower cost & less shipping from the same warehouse vs. 2 warehouses).

The next issue discovered was the 5/16 fuel hose in the tank. I did some research, and the line needs to be SAE spec J30R10. Most rubber fuel hose the parts store sells is 30R6 or R7, which is not rated for immersion in fuel. There are some alternatives like Viton or Tygon, but they end up costing as much as the 30R10 when you get the correct size and O.D. The 30R10 hose can be found as Gates # 27093 or NAPA H209. It runs $17/foot for the Gates (Amazon) to $29/foot at NAPA online.
