Hello family....I bought some of the 914 Rubber round relays when they came out but also have about 20 of the original round relays. For some reason I am having intermittent relay failure in my engine compartment relay board. When I realize that my fuel pump is not going on I swap a few relays and then the pump will run again. The primary theory is that the pins are not making good contact in the board sockets. I have cleaned everything and tried spreading the pins open a bit but still having an occasional failure. I am thinking that using brand new relays should be a better idea than trusting 50 year old relays....what say you?
Thank you very much,

Try the 914 Rubber ones. I had a prolem with the ones I bought until I spread the pins on them. Carry spare relays. Don't keep playing musical chairs with your relays you will never be able to narrow down what the problem is.

Good move I had a bag of relays I purchased from a member on here and they all tested fine ,also recieved spare ones when I bought the car ,slowly but surely the number of good ones is reducing.
Pulled a few apart and most had burnt/worn out contacts,took one and removed the guts and bridged the pins as a test relay which turned out to be handy.
