Its not that hard to put in an inline pump , but you might have to replace some of the line at the same time.With my setup I am running an EFI pump(to handle the pressure) and it works fine.I had a regular pump that had the right pressure , but it wouldn't keep it constant for the TBI , so I had stalling issues until I got the right pump.If you do a search under my previous posts you will find out more about what I did.The pump is a Holley by the way , good up to 35 PSI.
