I modified the fuel tube today with the addition of a fuel filter. Photo #1...I cut the fuel line back 1 1/2" and installed the fuel filter. Photo #2 and #3...I installed two 23/32" X 4 1/2" X .072" coil springs(from Lowe's) over some 5/16" fuel tube to create a tight "S" shaped bend with electrical tape(about 10 wraps) and zip-tied the electrical tape together in the middle to prevent slippage or stretching. I then installed the bent tubing onto the fuel filter.(a little grease is a big help on the connections) Photo #4...Final connection to the petcock. The coils springs "just" fit over the tube with very little to spare and are there to prevent the fuel tube from collapsing with the tight bends. Changing that air filter is going to be "much" simpler in the future and the added fuel filter protection will prevent any chance of clogged carb jets.     |

What happens to all of that once you push the tank back down?

The tank goes down easy and the "S" lays flat. Swinging the back of the tank up or down...no problem. The next time I lift the tank I am going to re-jig the wiring in that area a bit so it is easier to reconnect the fuel guage wire.

Don't be surprised if you think you are out of gas at around 90 miles when you no longer have fuel weight to push gas through those s-turns

Now, as a test you need to take the fuel level down to just above reserve and make an extended high speed run.

Been around the block more than a couple times with many vehicles.... The tubing is full round end to end guaranteed!!...no restrictions...and the bends lay flat...if a problem crops up this board will be the first to get a heads up....And if it works this board will be the first to get a heads up  ...The weather forcast here is starting to look better, so it may not be that long 'till I can take a "wide open throttle" rip up the highway...the reserve light is flashing so it will be the perfect test of my little mod...nothing ventured, nothing gained as they say. |

That's one thing I miss on the Valkyrie, a fuel gauge.

Fair enough, looking forward to the results. |

OK. I put my warning against bends in the line out there, and no vertical dips/rises. Good luck with that. I tried the same thing using soft copper tubing shaped on a bender with coil springs to prevent collapsing. Didn't work for me. Promise I won't say "told you so". If it works I will be puzzled why for you but not for me, esp since you will certainly have air bubbles in the line. Incidently you can get more usable length out of the OEM fuel line by replacing the plastic T with a brass one with screw-in barbs - supports a Dan-Marc right next to the T and leaves enough room for a filter the size of yours (which for me, the filter also impeded flow), and some line to connect to the OEM petcock. You can see the "T" in this shot. That's the bigger 121 Dan Marc with 1/4" orifice. Needed if you have high fuel draw like I do, hauling a Timeout camper.  |

The copper might be the issue, the "air" you speak of is likely vaporized fuel...the copper may have transfered engine heat to the fuel in the tube and vaporize it. It is anybody's guess, and like I said, I am going to see what happens once the weather warms up.

Neat idea putting the springs around the fuel line. Hope this works for you.

Went for a rip up the highway today to check out my fuel tube conversion.
I wound the bike up to around 100MPH full on acceleration with no hesitation or sign of fuel starvation. There was about a gallon of fuel in the tank. I continued on for about another 20 miles at about 70MPH and filled the tank and added some fresh stabilizer and injector cleaner to clear out any possible varnish from the gas I filled up with back in October...the real test for the fuel tube mod will come when the hot weather arrives, as that is when vapor lock might happen.

I have never had a motorcycle vapor lock, I live near Galveston and have had over 70 of them.
I would think a bike with a flat six would be really hard to VL , exhaust is on the bottom and the heads are are far right and left.
Glad your mod worked out for you...

Some here will recall that I modified the fuel tube a while back to make access easier. Well it worked great until the hot weather arrived...sure enough...vapor lock when under half a tank, so I had to switch over to reserve to carry on riding. I replaced the mod the other day with a straight tube, but kept the fuel filter in place. I know I know...I was warned. |

I hadn't heard back from icandoitfaster yet. He posted earlier in the year, with fuel starvation. In the end, someone mentioned inline fuel filter. Turned out he had one. It was removed.
He wrote me last week. He had gone through Death Valley at 54' (C?, 140'F), and no problem.
He seemed to have trouble in the desert heat, but also the elevation. So far, so good.

Hey Gordon...good meeting you and all the other fine people @ Valhalla. The fuel filter that I installed has a metal casing so it will be interesting to see if it is the cause of the problem. I have some foam pipe insulation, the kind you use on PEX water pipe, and will install some over the filter to shield it from engine heat if it is the cause...if that is not enough I am going to replace ALL fuel tubing and clamps this winter anyway as the bike is 17 Y's Old. |

I have been using a Golan Inc - Peak Flow Mini Fuel Filter - 5/16in. fittings, made of pleated, 304 stainless steel, 10 micron (.000392"), 1.000” diameter totaling four square inches of effective filtration area for over 25,000 miles with an electric fuel shut off valve. Made runs of 70 - 80 - 90+ for over 6 hours in hot and cold temperatures with an Interstate north of 1300 lbs. I have also run the mountains at altitudes above 12,000 feet and never a fuel problem. Fuel filter elements are washable and reusable indefinitely, cleaned with air and or soluble rinse. This works for me!

I have had no reason so far to suspect the filter of vapor lock, but I just removed the other mod so I will do a hot day ride soon to find out. |
