argue I have always welded the pickup to the pump.I have seen friends not do it and the pick worked it's way up so that it was out of the oil
leeving them with a problem with oil pressure argue
But I'f you don't have access to a welder you should make shure that it has a support that you can bolt to the pump.
And if you weld it use a nickel rod idea
If you try brazing it you need to get the housing to FKIN hot in order to braze It will distort the housing burningm
