99 200 sws2 hp fuel pump

[rolrandy]

1999 200 sws2 high pressure fuel pump issue.
I had a fuel starvation issue for several months in the VST tank.
Ended up being the vent line was plugged into the wrong port thus pressureizing it starving the pump for fuel.. fixed that issue ran great maybe 4-5 weekends in a row, last weekend it quit .. ended up that the high pressure pump quit. My question can repeated fuel starvation eventually kill the high pressure pump. pump is under warranty just want an warm feeling that was the issue.

Not sure that I really understand your question.

But, if it is "can an electric fuel pump be damaged if it is run without fuel available to cool and lubricate it" then the answer is yes.

Warranty covers defects. Running a pump without fuel available is induced damaged and would not be covered by warranty. That is, the pump was not defective. It was damaged due to an external event unrelated to the quality of the pump.

Take a brand new engine for example. Works just fine. It gets run without oil. The motor seizes up. That is not warrantable damage. It is induced damage.

yep I fought a problem for a couple of months starving fuel ..pressurized vst tank was found .. onced that was figured out worked fine for maybe 10- 15 hours run time maybe 4 weeks out and running perfect..
high pressure pump covered under warranty, just want a warm feeling 2weeks down the road same crap..
can HEAT? kill a pump or do I have a electrical issue .. that returns every 20 hours or so??

you can get a warm feeling by peeing in your wet suit while wearing it,
I know people to do that while cold water diving.

Not sure why you keep saying the HP pump is covered by warranty, there is a very good chance it will not be.

If there is no flow through the pump due to low fuel level in VST while running there is no cooling or lubrication in the pump as the fuel is suppose to give it the necessary lubrication and cooling. It will overheat among other things

There has to be testing to see if there is a electrical problem

The 1999 engine was bought 6 months ago from a dealer as a rebuilt good as new. the VST tank issue they worked on for a while after I bought it, the hp pump was replaced in that process 1 year warranty on the pump.
The hp pump was fuel starved quite abit in the process of trying to find the fuel starvation issue. So i think and hope the pump just degraded over time due to heat and lack of fuel

If you bought the engine and it was incorrect then(the venting issue), IMO, yes, I would expect that pump to be replaced under your limited warranty.

Now, if you had earlier assembled it incorrectly, causing the vent problem, that boo would have caused the pump failure. Your mistake, your dime...

yes it is covered have spoken to the dealer

but my original question was could fuel starvation kill the hp pump
boscoe99 seemed to believe it would.
it did take 10-15 hours run time to eventually kill ithe pump though

Good!

I agree 100% with Boscos post/ belief.

I can say re the Yamaha electric pumps (or any in-tank or surrounded with fuel, electric pump) for FI motorcycles, they need fuel around them to help cool them.

On a Yamaha motorcycle forum I'm very active on, most electric fuel pump issues are from guys running their tanks low on fuel, sucking up crap in the tank (fuel pump is in the tank), and the pumps getting noisy after running low on fuel.
