Well, after having exhausted all means of finding the rightful owner, I have decided to turn the lost tool into a charity auction. Details can be found here: http://www.vansairforce.com/community/showthread.php?t=33099 I encourage everyone to check out this thread and consider bidding/ donating.

When first starting the electric fuel pump,it did not draw fuel from the tank.I had to blow into the vent line to force fuel through to the pump. This means the pump is not self priming.This is a concern because if I run one tank dry,and switch to the other tank I want it to draw fuel. Have others noticed this? I have fuel injection and Van's Airflow performance boost pump P/N3090050. Instruction with the pump say-- "Ideally the boost pump should be installed so that under normal flight conditions the pump inlet will be gravity fed from the fuel supply" I installed it per Van,s drawings. This shows the pump on the floor of the cabin,but the filter is mounted vertically above.So it would not be gravity fed. -- George H.

Try draining the line to the pump, hook everything back up and then hit the pump switch again.I bet it will be ok...........if not...........call AFP? We also use these pumps here at work (same MFG) and have noticed that some of the pumps take 20~30 seconds to build up their pressure.

Then, while doing fuel flow testing, I inadvertently sucked the tank dry. I poured more fuel in the tank, and the boost pump reprimed just fine. I don't know what is inside these pumps. Is it possible that there are seals that dry out after awhile, and this prevents the pump from priming? Maybe the problem does not exist when the seals are damp. I will do several flight tests, overhead the airport, where I run a tank dry and then switch tanks. I will do the tests with increasing time delay before switching tanks.

I have them both mounted as low as I could on the lower firewall (below the level of the bottom of the wing tank). I have found (as you did) that once "primed" they draw fuel just fine from the tanks. Most of the EFI pump cautions will tell you that if no fuel to lubricate the pumps can quickly result in damage to the pump. So to address those concerns, I installed a small ("Van's" ) low pressure Facet pump between the wing tanks and the pumps. I turn it on before switching tanks. Once primed my pumps have never had to have the facet pump on for starting and sucking fuel. However, even the smallest air leaks in the line anywhere between the pumps and the tanks could cause loss of prime. I use the facet pump on start up (to keep possibly dry pumps from damage)and as mentioned - whenever getting ready to switch tanks. Its worked from me for 10+ years.

(It has hexavalent chromium in it as do some primers - strontium chromate, I think - which is a carcinogen.) The process involves adding sulphuric acide and something else.
