Fuel Filters

Noticing on rides lately, always a punter with a fuel filter issue, blocked, broken ends, leaking etc. are these isolated or has anyone here suffered FFF (fuel filter failure) ???
i dont run one, just a big loop of fuel line around and over the carb to provide a natural trap.

i entered the BP Mallee Rallee in 1978 on a hot XL 250..konis, pascoe "peace" pipe, mikuni carb and a hot cam....it was so hot the exhaust melted the fuel filter i had installed on advice that i must fit one. Luckily, the long length of fuel line just made it to the carb.... luckily i caught a whiff of petrol as it was falling apart! and didnt loose too much juice....

Oddly JC I've never had a single fuel filter failure in 47 years!

The one on my 500 was too small and it couldn't keep the bowl full through all 4 years .
The single shocks have one in the tank so don't run another ?
My gas gas one became a restriction after 5 years of neglect

what type do you use tony?

same here...would be real unusual to have a problem. i have seen more than one street or dirt bike with the "in tank" filter rolling around in the bottom of tank or torn open/not filtering. mine all have those clear plastic units with screen inside. no paper of course!

it would appear my stats are being biased by wierd coincidences....

I think I've used most types JC.

Just unlucky?

try a filter from Zip ty. super large element, mfg from billet aluminum, washable filter. will flow nough for a big KTM v-twin. plenty for a single.

you are very correct about making sure the filter is going to flow however..a big bore can run the float bowl low for sure.

I have always used the filter provided in the tank on many bikes, I have never had a issue.

Stop the crap getting into your tank first!

I have a fuel filter funnel with a proper fuel gauze!

You will be very surprised what comes out of new fuel when you are filtering it, it is not clean at all!

A proper fuel filter funnel will not only pull out every bit of crap but water as well!

This is the cheapest one I found so far on E-bay, it is only 3.5 inch diameter though.

Bunnings can get them in,

There are plenty of cheap funnels for sale but they will not pull out water!

A quick test for any fuel funnel, pour a glass of water into it, it should stay in the funnel!

Cheers, Dave.

have had 1 instance of water/crap in the carb and that was due to filling up without a funnel in an enduro in the pouring rain. 10 k's down the rd and it was dying on the mJ. so drop the bowl nut and all good again...was lucky i had to stop as ol mate i was riding with promptly got swept away at the next creek and i would have been expected to rescue him...dodged that one!!
