1.77cal BB bumped mine to 69psi.

Tell your girl that you are wearing a new Manly cologne called Rudolf(for Rudolph diesel) ....LOL....It sounds good on the surface but I don't even think my wife would go for that and she is a diesel enthusiast.

Ouch! $300


Man, you need to post stuff like that on here. I have a fuel bowl sitting on the bench lonly. It missing being in a truck to keep it company. We could have struck a deal.

That's cool but unfortunately my truck was in Maryland and i live in Pa. and didn't have the luxury of waiting!! Trust me if i had the time for the truck to sit i would've posted it up!! That's just the way it goes i guess.

i just took a Bolt and grinded it down to were the head was the height of a nickel which is .060 and the thread part fit inside the spring i didn't get a chance to get a Good reading do to the fact i had to clean the fuel off the floor.

how are u guys hooking up your gauges???

i just put clamps on the drain valve from the bowl to the copper tube then hooked a tube to the bottom of the drain valve then hooked a gauge to the bottom of tube and opened the drain valve then i turn the ignition on and looked at the gauge and all i saw was diesel shooting at me.

does that sound correct?

well what were the heights of the shims u guys used??????

and what r the benefits of this mod???

[pipelayerjdh]

That should work.

When I did my gauge that wasy I got more fuel all over the place than any other time in my life. The darn hose kept sliding off he smooth nipple on the valve. I ended up taking it off and grooving the nipple to keep it from sliding off. Then I got the alternator mounted fuel pressure gauge from DI and that fixed that problem.

how does the alternator mounted fuel pressure gauge hook up????

i checked the pressure today and after i checked it i moved the truck and it was spitting fuel out the drain tube with the valve closed. did i blow the O-rings out or something????

and what are the benefits of raising the pressure??

[strokin_early_99]

Raised pressure helps the throttle response. It also helps keep fuel to the injectors while under high demand.


The gauge mounts to the back into a #4 ORB hole that is plugged from the factory. You would need a #4 ORB to 1/8" NPT fitting to go in the fuel bowl. Then you need a hydraulic pressure gauge with a 1/8"NPT fitting on it and 10" #2 hose with 1/8" NPT swivel ends on it. Then it mounts to the alternator like this. DI use to sell this but I have not seen it on their website for a while now.
