brian89gp Posted January 15, 2003 Report Share Posted January 15, 2003 I am planning on getting a walbro 255lph pump soon and i got a few questions. How will the stock FPR react to boost? If i were to get an external FPR that states it flows 10gph (way too low) would that cause the fuel pressure to spike? And the 85-92 GM universal walbro pump is the right one? Thanks Quote Link to comment Share on other sites More sharing options...
brian89gp Posted January 15, 2003 Author Report Share Posted January 15, 2003 also, do you think a 190lph is enough? I don' plan to go over 70psi or over 4~500hp ever. Quote Link to comment Share on other sites More sharing options...
RedZMonte Posted January 15, 2003 Report Share Posted January 15, 2003 I am going to run a Vortech FMU in line with a ZZP Mini AFC. that should be perfectly fine for the fuel pressure. it should not spike. but i will worry about that if it happends when the time comes. As for the fuel pump timg and myself are going to run the Walbro 255 HP (high pressure) for the 85-92 GM's. it is a direct bolt in. Tom Wright did the same one in his L67 Lumina Euro and said it was a direct bolt in. RedZ Quote Link to comment Share on other sites More sharing options...
