Fuel pressure regulater shim mod?

[444ornothing]

Hello again, I want to get some off idle response out of my 99.5 powerstroke so i heard that by shimming the fpr I could accomplish this. Is this true and how big of a shim shall i use. I know i need to get a pressure gauge mounted to the fuel system but can some one with some tech tips give me more advice on the location of the regulator and necessary steps to do the mod.

What MBRP said. I did mine by those instructions and didnt have any problems! I dont know if your 99.5 is like my '03 but the regulator is on the driverside of the fuel bowl with the two torx screws and return line attached to it.

did it help as far as performance?

It made it idle a little quiter and smoother. Maybe a little better seat of the pants feel.

it may actually help with the Edge that you have too.

I could only find brass #4 washers. Is that suficient? Also where is an ideal location to mount the fuel pressure gauge. I'll give this mod a try and let you all know how it reacts.

Brass washers would work but are usually a soft brass. Wear issues ?

Gauge location is up to you. Many FP gauge kits come with bracketry for various location options under the hood.

Mine is in the Cab, via an isolator. (no diesel fuel in the cab due to a leak or failure)
