You need to check your fuel pressure.

You need to drill and tap the banjo bolt on the injector pump inlet. Use 1/8" npt tap and get the appropriate fittings. You will also need a needle valve to dampen the pressure spikes from the injector pump. Youre setup should look like this:

This can sometimes be a sign that its not putting out the correct pressure but in order to be 100% sure you must check the fuel pressure with a gauge.

Never seen one. This is an easy thing if you do a little research. -

your fuel pressure should be around 45 psi at wide open throttle if i remember right -

Yes, that should be for the wif sensor. No big deal.

if you installed a permanant fuel pressure guage in the cab and you would know when its time to change the fuel filter.


Whats youre idle at in gear or in drive? That can make a difference too -

I bought my FP gauge from Kenny at Ken's Performance. We went though some trials and got everything worked out. Isspro now sells the needle valve that is needed to dampen the pulses and Kenny should be able to put all that together for you. On my '98 I could uses the 24V boost bolt in the stock fuel filter housing but the '95 has a different housing IIRC....anyway....I'm sure Kenny can fix you up with a kit. -

Here is the link:

diesel, performance, dodge, ford, chevy, gauges, fass, smarty,edge, S&B Filters

He doesn't have it on the site but if you call him he'll know: (707)580-6782

I started with a mechanical gauge and we had some problems with the 12V beating the hell out of the gauge.....I put snubbers and needle valves on and even had Isspro send me different size pistons for the snubber.....I ended up with a EV2 electric gauge and the snubber and all is fine. Kenny was fantastic as well as Isspro to work with through the entire deal. I promise you will find NO ONE goes as far as Kenny does for his customers. -
