I have now tried a Wix 33042 in the CMP housing. It fits nicely with friction on the central spigot to make a seal but still slides under the pressure of the spring.
Since the one filter fits, they are all listed as being suitable for NSN 2910-00-945-2318 at
http://www.parttarget.com/2910-00-94...2318_GF12.html and some of the manufacturers' listings also confirm the cross reference I think all of the following should be interchangable: ArvinMeritor GF12, Ford/Motorcraft FG-11, GM 854425, Delco GF133, NAPA 3042 (sometimes FIL 3042), Fram CG5. Add from manufacturers' cross reference: Baldwin PF860, Luberfiner L8305F and Fleetguard FF132, White 871646, Hastings PF860/G338, Carquest 86042, WGB S224CP, Wartsila France F3229, Big A 95042 and possibly/probably others. The NSN listing seems to be mainly for aviation use, showing these filters used in B52, F4 Harrier and C17 among others.
I have also found that the spring that PeterDebella sells as "WO-A-1262 Spring, fuel filter strainer" fits the filter from my CMP housing.
When installing the Wix element, I found that I had to reduce the surface roughness of the central tube so that the filter would slide freely under spring pressure to make good gasket contact at the top of the element. I suspec that the roughness was the result of time, not a basic misfit as the original strainer element doesn't seem to fit differently before and after. Also worth noting, in addition to the gasket(s) mounted on the filter element the Wix came with the gasket between the housing halves (but not the one for the hollow bolt securing the 2 parts of the housing).
