BIG, I assume you've bled all the air out the system?
That can cause the 'bumping' you describe.

I'm also sure you're aware the F*rd rack and Chevy pump operate at different pressure/flow rates.
Has your pump been adapted to suit?
Just a thought......

You might want to take this one over to the Hi-Po section for more input/advice. (If you haven't already) [/quote]

Thanks Jock,

I hadn’t thought about the air in the lines. If bleeding them doesn’t work I’ll move this over to HiPo.
