83 venture fuel line ?

[noel cassidy]

Having problems with grit in the carbs and believe it to be the fuel lines deteriorating. What is the proper size line to use? Are NOS fuel lines available? Appreciate any input.

I think i used 3/8 from Napa when i replaced all mine. Works fine. New fuel filter will be needed and check the tank for rust particles.

 

The OEM lines have a couple moulder bends. But you can make that work just fine.

I found 5mm black polyurethane fuel hose at my local Oreilly's that works fine. Doesn't have the layered construction with the inner core wound with reinforcing cord and outer cover like common auto fuel hose that falls apart over time.

RE: the tank, I removed the fuel level sending unit so I could dry the inner withcompressed air, then used a long handle brush and shop vac to clean.

Whole fuel system completely cleansed, but didn't check the short carb fuel inlet pipes where there was a hiding grit that temporarily stuck one inlet valve.

I had a similiar problem, and I changed my fuel hose also. I thought it was fixed, but then started having problems again with the needle valves not sealing. BTW, I'd changed the needle valves last fall. This time, I decided the only thing left was the fuel filter. I shut off the tank petcock and pulled the fuel filter. I carefully ground the seam that held the filter together, and found that the filter element was only a fine mesh screen, and also that the screen wasn't retained correctly, so in effect the fuel filter was bypassing. The bad fuel filter was a NAPA type, and I think the number was someting like 3007. I went to AdvanceAuto, and the counter man came back with a fuel filter that was about the same size physically, but had a paper cartridge for filter media. The housing was also clear, so I could see that the element was retained well. I've got about 3,000 miles since I changed the filter and everything's been fine. The new filter was a little shorter than the original, so I used a couple of wire-ties to keep it in the bracket.

 

I flushed the crud out of the needles and seats by unplugging the fuel pump (the connector is under the left side cover, underneath the very bottom section. It's a 2 conductor connector) and letting the bike idle until it stalls with dry carbs. Then plug the fuel pump back in and start the bike. When this happened on the way to the Rally in Ga., I flushed it twice to make sure I got it clean and it was OK for the rest of the trip.

thanks for all the response. My plan is to replace the filter and all the fuel lines. Then try the carb flush. Keeping my fingers crossed.
