Fuel Filter Questions

Fuel Filter Questions
I am about through with the restoration of my '71 442. I drove it around the block this evening for the first time in many months. The engine has less than 500 miles on a major rebuild. I had the carb rebuilt too. I put an inline fule filter on the rubber fuel line that leads to the fuel pump. Under WOT the car takes off strong but then falls flat-as if it is completely out of gas. Do you think the placement of that fuel filter could be the problem? Float level? Also, the little rod that controls the openning of the secondaries has been removed. Perhaps this lets too much fuel into the carb, causing the big stumble?
Thanks for any thoughts.

I doubt it is the filter...not knowing details on the motor re-work ( cam etc. ) I can only guess your fuel pump is not re-filling the fuel bowl fast enough. There is a high volume mechanical pump made by Airtex that usually cures the symptom you describe.
As far as the Secondary to Choke pull-off rod, I would add that back. Secondarys opening too quickly will manifest itself as a stumble right out of the hole. But without the rod you mentioned in place, the secondary Air Valve tension spring is probably set pretty tight to offset the momentary lean bog.
Just my $.02 worth

I will likely try that Airtex fuel pump.
