I’ve personally had very few problems using aftermarket fuel filters designed specifically for the GL1000 such as the commonly available EMGO model. However, there have been some reported failures with such aftermarket filters. Fuel leaking from a fuel filter is more than a nuisance…it’s a very serious fire hazard.
Here’s a tip to prevent problems with these filters. The probable cause of leaking aftermarket filters is over-tightening of the 2-part bracket that secures the filter to the front of the fuel tank. If the aftermarket fuel filter has a diameter just slightly larger than the OEM spec, tightening of the retainer screw can put to much stress on the plastic filter housing which may cause it to fail eventually.
Remember, the OEM filter and correct aftermarket substitutes all have molded in retention ridges. These secure the filter in the bracket without putting ANY pressure on the filter. In fact, once the 5 mm retaining screw is lightly snugged, you should be able to rotate the filter in the bracket with minimal effort.
If you can’t rotate the filter within the bracket, you should put a 5 mm plain washer between the 2 bracket halves to relieve any excess pressure. This will prevent any premature failures of your filter.
I use a drop of BLUE Loc-tite to prevent the retaining screw from vibrating loose.
More fuel filter mounting tips:
- I always check to make sure the filter has no internal obstructions before mounting. I do this by gently blowing through the filter. I’ve found a few with manufacturing defects that were 100% blocked!
- I always vigorously shake new filters before mounting. If I detect any “rattle,” this means that the internal filter media is loose in the housing. This is an important test. A rattle means that fuel can by-pass the element unfiltered. If you detect such a rattle, the filter should be tossed.
- Whenever you change the fuel filter, be sure to flush the fuel pump and outboard hoses before reconnecting everything to the carbs. Debris often collects here in lightly used machines. Strongly consider replacing your hoses if there is any doubt about their condition. Be aware that old fuel hoses can deteriorate from the inside out and shed small rubber particles wreaking havoc on small carb passages.
- Be sure to observe the flow direction arrow embossed on the filter housing.
