Strange you’d come on a forum rather than ask the question directly to get the correct answer the first time…
The Borgeson box operates at a high pressure than the original box. Most Saginaw pumps are fine. The Saginaws we sell have the target pressure and flow set already.
Your 67 can have either pump. You didn’t mention which one you have.
If it’s a Saginaw, you can try removing all the relief valve shims.
If it’s a federal, we’ve sold new ones with some luck. If you are to convert to Saginaw, the only tough part is the pulley is not reproduced and can be tough to find.
