Oil Pump Info
This site gives some useful information on how to fit a type I pump into a type IV, so you are not limited to the cast iron Melling pump as a replacement. http://home.att.net/~airdoc/T1oilpumpmod.html

Chris,
Truth be known the iron Melling pump a replacement fior a type 1 pump. Melling tells you to check the drive flange for clearance before installation. I have heard of oil leaks because people don't check this and the pump doesn't seal. It's also very hard on the cam bearings. neil |

Here is some info I located and the reason for posting. Through personal experienced using a cast iron pump I show extremely high pressure when cold and very low at idle when hot.
" 3. We do not sell or ever recommend using a cast iron body pump (such as Melling etc.) in the air cooled VW due to improper expansion rate as compared to the magnesium case. It normally provides far too much pressure when cold and not enough pressure due to leakage around the case hole when hot. It is common for them to suck air around the pump body from the cam gear area. This air in the oil radically reduces oiling ability, yet will not turn on the warning light."
