Easy high pressure piston lift pump question
How would one know if they installed a HP piston lift pump by accident? How bad would the IP leak?
Just curious because my IP leaks pretty bad now. I got like 8.5 mpg city last time I topped it off.

Outwardly, they look the same. The low pressure LP will have a bronze bushing in the piston bore to accommodate the smaller piston (left).

I was given a brand new piston lift pump from a friend. He has no reciept and no idea was application it was for. Basically it was part of a master rebuild kit for a marine 12 valve. I have not opened up the pump to see if it is a high or low pressure. The pics BC847 will help me determine that. My question is: Can a person interchange the internal parts from HP to LP, or vis versa? I really would like to know this, otherwise I might have a HP pump this is useless to me.
The 2nd gen LP piston (left) is bigger in diameter than the low pressure LP we commonly use (right). The springs are different as well.

Also if you were to run a pressure regulator with return line, would that help to level out the fuel pressure to the pump and make more power because there is no pressure drop?

I personally want to convert my HP lift pump to a LP..........can I do this?
I am assuming you can buy a new spring, piston, and bronze bushing? I realize you can regulate, but I prefer it to be a LP pump from the get-go.
