Cereal Box? Are you checking materials with a micrometer?

Yes, Micrometer. Tis gasket is between charge pump and valve body, might make a difference if I used .032" which I have. Thanks for all the thoughts.C/CT

My local fastener store, called Hokel has high quality gasket material in various materials by the square foot. I know the national seller McMaster-Carr has a wider selection. Some good car parts places and maybe Fastenal also carry sheets of gasket material that you can select by thickness and survival in the presence of oil or water or fuels (probably more than one variation for different fuels).
www.mcmaster.com likes to think its purely an industrial distributor so you have to make up a "company" name, but they take credit and debit cards and take orders on line or by phone and don't waste much of your long distance phone charge. But to do a good phone order you need to have a catalog and getting one of those takes ordering by the bushel each month or each week. Its all on line now too.

Copper Seal is great stuff to use....that thing of a gasket you could probably apply the copper seal, let it start to set up a bit and install it....it would be stiff enough to not all smush out and put you pretty close.

if it says .010 you better get a paper gasket about that size. this is a close tolerance pump. put it together with no gasket or RTV and it will lockup when yout tightne the bolts. Normal computer paper is about .003 , you need 2 layers of the heavy duty stuff or brown construction paper. How about a brown paper bag from the grocery store?

IBM cards were .007" thick. Brown paper or IBM cards may not handle hot hydraulic oil at 3000 psi well though. I checked the Fastenal catalog a bit ago. No gasket material there.
The only .010 material at McMaster Carr is Gore tape, like 1/2" wide by 5' long catalog number 95705K21 for $32.75. Its rated at 3000 PSI and its mostly Teflon with fiber reinforcement. Might be an application where the manufacturer's product is the handiest solution, no matter what the cost.
