I'll check for the inline dash-12 filter. What is the brand and model of the pump ? Pace Products : BG ? CD2000 ? Compact C ?
And can you publish or send me pictures of the part on ebay, it will help me to see exactly what you are looking for, as I can't access to these pages from here (UK only).
Thanks.

The pump in question is a weaver brothers 3 stage pump,
Pace external remote oil filter and pace tank,

Nothing but the best of stuff for such a serious system. failure is not an option...lol

Thanks for the pics.
I will not find exactly the same parts, but something approaching, especially for the in-line filter. Problem is : I can't see what it the other connexion on your picture. One end is a male -12, but what is the other side ? Where do you fit the filter on your line ? Here is a example of what I can find for you :
Attachment 1276
Mesh filtering element for oil are 238 or 595 micron.
This ally part + stainless steel mesh filter are anyway never cheap. Around the £100 I would guess.
For the scavenge filter, I'll check tomorrow.
Let me know if the filter on the picture can be of interest for you.
Hope it helped.

yes i know this type of filter and they are expensive. can can get them from the states so about £75 plus P+P

See what you can come up with. thanks BJ
