I was curious, what is this shimming procedure to up the fuel pressure? My truck runs ok I guess, but would doing this gie me better throttle response? If so, how do I go about doing it? Thanks!

 

Hey Mongo. I bought the shim kit from I think Diesel site. It's pretty easy to do also. It takes about 15-min or so to do. I made a pressure gauge to monitor the fuel pressure. It stubs in a port at the back of the fuel pump. My pressure started at 58 psi. There are 4 shims in the kit,045,055,065,075. I started with the 65 shim and it raised my FP to 65. I then removed the 65 and installed the 75. My fuel pressured didn't change. So I left it. Im pretty sure My fuel pump is not up to the task. It's the stock one and when I push my truck hard it kinda falls off on the top end. I know of a few other guys on here that have used a BB to get the same results. I did take some pic's of the gauge I made and also checking my fuel pressure. They are in the link below.. In my Shoe Box Pics.. My truck seems to run alittle quieter too. It could be just me though. Take Care..Country

 

Ive heard about the bb thing also ,but were does it go ?

 

Inside the Fuel Pressure Regulator between the cap and the spring. The FPR is on the right side of the fuel filter housing with the return line coming out.

 

Thanks for the Info Is this worth doing ? an whats the gain. Thanks

 

The extra fuel pressure can smooth the idle a little and give more responsiveness in the pedal. But raising the pressure can send a weak pump to a quicker afterlife.

 

this is some great info. any one know where to get the shim kit

 

Try this out. This is where I got mine from.http://www.dieselinnovations.com/tec...structions.pdf

 

Thanks country- I'll probably be getting a set this pay day (bills...)

How can I tell if my OEM pump is on it's way out? Will a pressure gauge indicate if it's dying?

 

Here's another option. The price of a screw.

 

Hey Mongo Sorry about the delay. UHM well I assumed that my pump is bad or better said week, because I've read in other posts where some of the guys have had to replace one shim for a smaller one because the F-Pr is to high. Like 75-85 psi. Well mine wouldn't go above 65 even with the biggest shim in place. I left the gauge in place, in the engine compartment to continue to monitor the Fuel Pressure. I did the mod about 4-weeks ago. I took pic's also, they are in the link below.. Take Care. Country

 

Yeah Tenn is right. This method works as well. Thanks Tenn. Is this what you did Tenn?

 

No, not yet anyway. I just bought a gauge to check mine and will get it on there eventually. I neet a longer section of hose to check it under load. Been doing a lot of work on the boat. Anyway, I want a baseline before I make any changes. Besides, my truck is running very well right now. To answer the question, I will be going the DIY route if and when I get ready.

 

Sorry guys Bump

 

Sounds good. I saw that you bought a guage. I was gonna offer yah mine for loan if you didn't want to buy one. I know if you buy the glycerin filled gauges they get alittle pricey. Mine cost me $30.Plus the SS hose and fittings came to about $45 bucks. Not bad for a tool. Hey that goes for you too Mongo. If yah need the gauge, let me know, I'll mail to yah. Just mail it back when your done.Take Care. Country.
