I need to upgrade my fuel pump for the 175 shot im running, will my stock fuel pressure regulator work ok with a 255lph pump and a 175 wet kit? last time I went to the track my fuel pressure dived to about 35 psi and I had a nasty backfire. Fortunatly no damage but it kept me from making a clean run, any other suggestions?

 

mine works fine with a 255 and stock regulator with my 175 shot.make sure the filter is in good shape also.

 

thanks I appreciate your help.Im trying to get this thing sorted out.
