Red armstrong fuel pump relay caput

[SNOWBIRD]

HI,I have a red armstrong TWIN PUMP system with his hot wire system and hobbs switch for the second pump......MY PROBLEM is the fuel pump relay in his system has become defective 3 times ...the relay will usually last about 100 miles and then i have a no start condition....plug in another relay and it will start up this is on the primary pump ,i have no problem with the second pump side or hobb switch...help also no fuses blow.

I just ordered some fuel pump relays from caspers just in case the local auto parts is selling defective 40 amp relays ,i tried to speak to john spina but he is out for a couple of days..I also ordered a fuel pressure guage (autometer) to mount on the hood to see if my fuel pressure would fluctuate just befor the relay would go...I NEED it anyways
