Fuel pump question

Also if your going to do a installation like Frank you have to get with us, because the pumps are configured special for that application.

Hi Guys...I will post pictures of my system as soon a I get a minute.

I bought the presure relief valves from Don and I used NAPA pumps.

Built a pump/filter/pressure relief set up. Each one of these i instaled in each wingroot.

To run the left tank you run the left pump and vice versa. The Van's selector valve is used but it plumbed as an on/off valve...The valve has an extra port which allows you to do this.

To make the pump/relief manifold I simply welded a few fittings together from my local hydraulics store.

Pumps are rated to run continuously and have been doing so for close to 300 hours.

You will need two Andair non return valves from Van's and filter for each pump.

You could put both the pumps on the floor if you wanted to, but the engineer in me wanted a "hydraulically correct" solution...I.e pumps as lclose to the tank as possible.

I think Don and I were talking about specially configured pumps at one stage but I did'nt end up going that way...I.e I just used a standard NAPA pump.

I'll post my system pics ASAP...

I do not want to hijack this thread, but it is certainly related!

OK, call me stupid,...... I know!, I know! it is clearly stated in the manual that if you undo the electric wires to the pump, the warranty is void, but considering that these pumps normally do not break down and I am not going to send a pump back from Belgium to the USA to be repaired and the fact that I am stupid, I still undid the wires to make the connections without a splice, directly to the pump. Guess what happened? Right, I snapped one of the studs right off, beyond repair!

So, for anyone reading this, do not undo the wires, but make a splice. I thought my inspector would not like to see the splice if it is not really necessary, but this is going to cost me a couple of hundred $!

I hope this keeps others from making the same mistake.

Regards, Tonny.
