Question about Honda Motorcycles
82' Honda Magna fuel pump does not pump. I hear no clicking where I used to hear it a lot. How do you test the pump?
Hi, Allen the following is a systematic procedure for diagnosing fuel pump issues designed to keep "DRACHMA" to a minimum. If you need parts check with Amazon and eBay first to keep costs down.
1. If your pump does not turn on check the pump fuse and relay and all wiring including connectors for corroded, broken, or loose pins/sockets.
1. Normal fuel pump pressure is 3-5 PSI.
2. Check any rubber or plastic tubing for age-related pinholes by removing and plugging the ends that connect to the fuel valve and then turn on the ignition switch and watch for fuel streams exiting the pinholes, if any exist, replace tubing as necessary.
3. Check for a clogged a primary fuel filter that comes off the bottom of the pump to screen out big rocks and clean as necessary.
4. Check for a clogged secondary fuel filter that's outside if applicable by removing it from the system and replace it with a short splicing tube turn on the ignition switch and recheck fuel pressure if pressure increases to normal pressure you need a new secondary filter.
5. If all the above check out OK and the pump is not functioning properly then you need a new fuel pump.

Just disconnect the main fuel hose from the carb rail. Ensure that you have switched the fuel **** to reserve and this will allow the reserve tank to empty. Not all the fuel is going to come out unless you blow air into the fuel tank filler, this will then get a large percentage of the fuel out. Hope this helps, let me know how you get on.

Your model 95 or 96 VF750 Magna does not have a fuel pump. I believe the part you are talking about is the vacuum fuel petcock assembly. The part is only sold from Honda as an assembly.The part number is # 16970-MZ5-003 and runs about $120.
