I just installed a Walbro, here are some of my observations:
- OEM pump is *extremely* well made, in fact it appears to be much better than the Walbro. I cut apart the old pump with a sawzall. This way I could use the embedded threaded connectors --no cutting of the OEM harness-- and used large heat shrink to cover the connectors. (add an hour to the process and I don't recommend it except for folks that do not want to cut OEM wires and have a decent amount of tools.)
-My OEM had been obviously worn out at 105K miles. My occasional false starts have now vanished and I have a significant more HP. (No, really....I can take certain hills in higher gear than was possible before and throttle response is noticebly better.)
- Use vice-grips to "stage" the hose clamps on the filler neck. They are very difficult to spread from their relaxed state. Almost no room for human hands either...so use the vice-grips to grab the clamps and keep them stable until you reinstall them.
- The tank is VERY light. Easy job with jackstands on garage floor.
- Only had to remove the front side of the tank straps and loosened the rear nuts and swung the "L" straps out of the way. Minor PITA to keep them out of the way when reinstalling the tank.
- Have some undercoating spray to fill in the areas that you will knock away during the installation.
-The hardest part of the job IS draining out the fuel.
