Adding inline fuel filter

[cannondale27]

No way to install a inline fuel filter without clamps? I understand the molded plastic fuel line and why they did it. But how else can you install a filter?

They make a tool to install that hard line on filter using no clamps. It’s just a reminder to not trust them. Since this happened to me I look for leaks before every weekend ride and if I smell fuel will stop and fix immediately or let sled sit.

8 AN O Ring Boss to 5 | 16" Hose Barb Fitting

These unique fittings feature a -8 AN o ring boss port on one end | and a 5 | 16" hose barb on the other end.

I'm about 99% sure theses are the ones I used on the ends of the fuel filter itself.

So the input and outlet holes on the filter are not machined with tapered pipe tapped threads which requires the oring? I would have thought it would have a tapered pipe thread in it. That would allow you to just thread the fittings in with thread sealer

I do not recall. And to be honest I was slightly unsure on what fittings to use.. I used the one I linked to.. No leaks this season on it. .. But I was definitely checking and keeping a eye on that filter and fittings.. I even drew a paint line on them so I would see if the fitting loosened up ever so slightly.

Machined threads w silicone o-rings. Filter made for race car applications, some up to 100 psi EFI. I wouldn't trust that plastic fuel line even though it's used allot under the hood in modern automotive applications. Be careful using clamps because clamping could crush hard plastic out of round and cause it to leak or break.

The straight fittings with an o-ring will handle higher pressure than tapered pipe thread. This is why you never see tapered threads for high-pressure hydraulic fittings. If they ARE threaded and not a JIC thread, they typically are a straight thread with a copper or rubber/steel crush washer.

The only way would be to find a filter than had the -AN male fittings machined into it. Then, you would need to order pre-made lengths of hose that have the -AN female fittings machine crimped on the ends. At least that is the only way I can think of.

Just a heads up for you guys adding a filter. Dont trust clamps. Any clamps. I believe mine failed from corrosion jacking. Dont know but think of all the newer vehicles. No clamps. No issues. Just saying.

Recalled Fuel Line Leak

Not good! Knew I smelled gas last night daughter said she didn’t.

You do realize that the fuel hose is clamped on the fuel pump outlet, right? At least that is the way it is on my 17 Sidewinder.

I think he is saying don't trust them over time.. The newer Plastic like fuel line is cut and sealed/crimped so to speak to size and length. It has no clamps of any kind on it. And is not flexible at all(its got the proper bends built in). This was what they went to on the newer sleds.. Not sure what year it started but when they went to another gas line material with no clamps they eliminated the fuel filter(from viper) (sidewinder never had one).. Me personally I will take my chances with clamps and value the inline fuel filter protecting the injectors from build up and loss of efficiency.. I think a guy could replace the fuel line and clamps every 2-3 years? That may sound a little overkill but when your dealing with a gas bomb(potentially) its money well spent.. Buy 25 feet of the gas line and a bunch of clamps. Its not a big job at all and maybe some peace of mind?

That leak in the link was also on a steel filter. The Viper fuel filters are steel. The filter you installed and the fitting are anodized aluminum. Those anodized fittings are not going to corrode unless they get scratched through the anodizing.

I agree. But inspect religiously. That’s all.

Did the Apex/Vectors have any secondary fuel filters? These machines are racking some very high mileage and I never heard of a fuel injector being blocked or a fuel filter needing to be changed.

Just a little bit overboard,

If you run them tuned 17+ psi. on cold days(o degrees F) they are maxed out on injectors. Below zero is even more critical. Maxed out injectors that have any restrictions(dirty) will throw a smaller percentage of fuel and in turn raise your AFR numbers = possible lean deto and engine damage. Guys are running a lot closer to the edge of safety then they think especially in colder weather.

Absolutely positively.
