    Thinking my Traveler has Covid...
    So it's been running well enough until yesterday. The fuel pump started getting loud then the motor started to cough under acceleration. It got worse and worse on the way home. By the time I had limped home it would start and barely idle in drive for a little bit before stalling. Feels like it runs out of fuel but I still have over half a tank. I haven't had a chance to check for codes yet but the light was flashing. Ideas? Thanks

    That was my initial though. It is possible though unlikely as it is the pump that came with the HFI kit. Less than 100 miles on it so far.

    I should add that I realized I used 5/16 rather than 3/8 fuel line on the supply side. Not sure how this might be my issue.

    I'll bet it doesn't help as you can't get the required flow needed.

    Im sure it doesn't help but I don't know why it would get worse over time if it were the only issue.

    check for codes? Do you have a modern engine swap here? Or a Hamilton FI kit installed? Something else? Not sure I fully understand your situation, but I'm speculating non-stock somewhere.

    Not sure what you're looking for if you know there's a problem and haven't provided any definitive info to go by.
    The pump will NOT set a code.
    Poor fuel flow causing a lean condition will.
    The SES light does not flash on and off but will come on at a hard fault and remain on until the fault is cleared or the problem goes away.
    It will do a rapid flash that will not go away if you get an error 51 which is the chip or the ECM.
    Instructions state 3/8 from pump to engine and 5/16 return.
    Smaller will restrict flow.
    I would start at the filter, if it is not still clear and clean then it needs replaced.

    Replaced all supply lines with 3/8. New filter. Starts off running fine but after about 10 minutes the flow through the filter is significantly reduced and the same sputtering and dying occurs. Thinking the pump is toast.

    Could your pick up in the tank be plugged?

    It is possible, but I would think I wouldn't get good flow of fuel at all if this were the case. Seems to get worse with time. The pickup was new when I installed the poly tank a few years ago.

    Did you leave the gas cap off?
    Did you flush the poly tank prior to install?
    Did you install the sock on the pickup?

    Never leave the cap open
    Didn't flush the poly tank. I did ensure no loose injection mold pieces or other debris prior to installing.
    I did install the sock.
    I'll try dropping the tank after trying a new pump. I'd honestly rather spend $100 for a new pump before dropping the tank again to check the sending unit. There is no drain plug and it is mostly full. Ugh.

    What is the part number used on the HFI pump?

    Leave your cap off and drive it.
    Then if it still does it, leave the cap off and then disconnect from the pump and blow back into the tank.
    See how hard it is to blow back. It should get easier once the fuel is pushed out of the line.
    Use a light and look at the hose going to the sender and ensure it is free and not pinched.
    If you can, also look at it while idling and see if it is getting sucked flat.
    May need to remove rear wheel so you can see it.
