BX lift pump issues.

[farmerNick]

Welp, the 3rd lift pump is now doing what the 1st two did...stops working after about 5-10 mins of work. Work = just driving.

1st Lift pump quit intermittently.
I have removed the in line filters. I installed a larger inline, water separator type bulb filter. Installed 2nd new lift pump. Took about 30mins of work before it happened again... SO, No changes. (I'll put another in-line before the lift pump, after I solve this issue.)

I installed a 5" cleanout/access in the top center of the tank. Siphoned empty. Dried, and vacuumed inside the tank. Installed a screen around fuel port. Also added strainer to fuel fill opening. Tank is clean. Installed 3rd new lif pump. Worked for about 20 mins. So, Still no change.

What is killing these lift pumps? Or is it that they are Chinese crap?

I think you nailed it on the head with your last statement

Heck my BX23S ran for weeks without a lift pump.... only noticed the connector off of it when I crawled under to see 'something'. Saw the connector unplugged, reattached it and naturally forgot WHY I was under in the first place.

If Kubota pumps ,from Kubota.... I'd go back and ask. A good dealer WILL refund/replace AND look into WHY you have THREE bad ones.

How is that possible? The fuel line would be separated.

no, it just didn't have any power.....

His electrical wiring connector was unplugged, not his fuel hose.

You're buying the$12 pump online? They're only good for twenty minutes.

Where did you purchase the pumps from and are they OEM?
Did you apply another source of dc voltage to the pump? Maybe it's the wiring.
