High/Low pressure pusher??

[merryman]

I am ready to add a pusher fuel pump, but I am puzzeled/confused about one issue.

Why use a low pressure (ie Ted uses a 7 PSI ) pusher? Why not a 15 PSI?

From Steve's article in issue 34 of TDR, it sounds as if he used a high pressure pusher?

I do not mean to suggest I think one should, just puzzeled and want to be sure I understand what I am doing.

What is/are the reason(s) for going one way or the other?



Thanks for the help/opinions.

Oh, I am not in trouble yet, I have about 12-13 PSI at idle and can pull it no lower than 6 PSI at WOT.

The pump I used was a low pressure, high volume pump.

Use a high volume low pressure pump for a booster like Steve did. The idea is to guarantee a steady flow to the original lift pump. The volume has to be enough to maintain this stead flow. Kind of supercharging the lift pump.
