Since I have built this motor (which has maybe 5 hours on it) I have went thru 2 fuel pumps, It is currently being ran on E85. I purchased a new fuel pump from one of the site vendors after the old one locked up solid and the second one only lasted about an hour. I tried shocking it loose with 24v and all the other tricks I could think of. I sent it back to the vendor, I get a report back that they shot some compressed air thru it and it took back off and that they were sending it back (which I also tried). I received the pump went to put it back on the machine it is locked up again...GRRRR! After some tinkering It took back off, now after sitting for a few minutes after shutting the motor off it will lock up again and I have to thump it with my hand to get it to take off. Has anybody had issues like this with these stock pumps.
I have talked to another local member that is running E85 also, he said that he hasn't had one issue.
Fuel pump keeps seizing.

I went out today to see if it was still working, when I came in last night it was still working as it should. As I figured this morning it was locked up again and I beat on it to no avail. This pump was a brand new one, only has an hour of run time on it. I guess I'm a little grumpy at the thought of having to pay over a $100 for a new pump already. All the connectors are either new or are clean.
