I believe I resolved the issue with my carbs but now it's back to the original issue. Took the bike for a test ride and it died. A ways into the ride, it lost power and eventually died. It was the problem at first. Question is how often do the vacuum petcocks and fuel pumps fail and is it possible to bypass them and go to a manual fuel petcock.

Start a new topic. We are in the dark....Tell us about your bike.

Vacuum petcocks are used on the '84-87 FJ's and fuel pumps are used on the '88-'95 FJ's.
Vacuum petcocks are not used with fuel pumps.
Proper fuel line routing is important on the vacuum petcock bikes. (see my sig. line)
Fuel pump bikes can have the fuel lines tied together to bypass a failing fuel pump.

3) Replace your old stock rubber brake lines.

If your bike is gravity feed its sounds like the classic kinked fuel line .If kinked you can ride about 3 km before it begins to sputter then bogging then stopping=)
Make sure you route the fuelline as the sticker on the airbox

I had the similar symptoms with sticky diaphragm in the petcock if the bike sat for a long time.
