Well i was getting 65psi at cold idle for the first 60 secs, then absolutely zero. i tried it several times. Needless to say the engine hasn't run long enough to find out what its like hot.

4wd hp pump and pickup, 2wd sump on a 200 block. I measured the clearance between the pickup and the sump - its 6mm. Well it was untill i cut the pipe into 3 bits and had just the two brazed back together. Should have around 15mm clearance now

Will find out in about 3 hours if its worked.
