Newbie
So I have a 95 silverado..I stored it many years and since bringing it out it naturally needed a new fuel pump .I put in a new tank with preinstalled fuel pump...Since then the vehicle has had an issue of running rich...after firing the parts cannon [ new coolant sensor,injectors,map,distributor and module fuel filter]I started thinking about the fact that almost all replacement fuel pumps have too high pressure for what there advertised to fit...I put snap on fuel pressure guage online and sure enough the pump is putting out around 30 psi..according to chevy the correct pressure is 15 psi...even though this may not be my issue..I think I should try this.the factory regulator in the tbi may not be able to return this much excess to the tank.so two ways to fix.....1] fuel pressure regulator....or 2] drop tank and put in pump with 15 psi....here is question does anyone know of a fuel pressure regulator that will drop into 15 psi? Most of the regulators seem to only go down to 30psi from higher...the round carburetor style ones with no return outlet only go up to 5 psi..second question does an y one know where to get an in tank fuel pump that puts out 15psi? Chevy discontinued them and they are offering those cheap fuel line mounted thumpers..that usually burn out after a month...thanks for any help!@
