It would cost hundreds $$$ and perhaps more grief to replace the SVT filter assembly. I moved the assembly 1/2" away from the chassis frame and after some hours surfing the net found an
oil filter, with a bi-pass anti drain valve, that will fit (Wix 57007R) racing filter. It is much larger than the FL-1A type filters and more expensive but it will work. I will order 6 from Ebay and will most likely have enough filters for the next 5 years!
