KB is it just a matter of gage readings? Or do you have some power or suspicion of loss of power problem you are chasing...

Most of the time automotive gages are not very accurate at all but are still useful for general relative reference. In other words it isn't too meaning full if the Gage reads 200 degrees (or what ever) if the true temp is 208 degrees and each degree of raise or drop is within 1 or 2% of a real degree. To make an electrical gage real accurate requires a adjustable sending unit or gage movement spring setting. Also my experience is that the most accurate portion of all electrical gages in in the mid scale area and gets very inaccurate at either left or right max or min portion of the scales. So for a 32-35 psi up to 47-50psi desired spread you need the 30 to 60 PSI in the center and thus should have a 0 to 90 psi gage preferably a full 270 degree sweep type.

Most of the time mechanical are much more accurate...but caution... mechanical fuel pressure gages are very expensive and for my money are not worth the added expense

Is your regulator Accurate? Adjustable? Years ago I over pressurized and used a regulator for feeding Holly carburators... needed to reduce 35 psi (high flow) down to 11 PSI... I finally found ( after several fixed pressure styles that did not have any accuracy) a Acell(sp?) brand variable unit that did the trick

 

I'm experiencing a slight loss of power, slight enough that most people wouldn't even realize it, but I do. I have too much money invested in this thing to have it not producing the power it is capable of. Do you know if anyone makes an adjustable pressure regulator for the Triton motors?

 

you mean like this?

I ran an A-1000 on my 5.4...

I never had low fuel pressure, thing was easy to install, and even looks good.
Will flow 600 lbs./hr at 13.5V and 45psi...

 

BigF350, Who makes the A-1000 you mentioned?

 

follow the link I provided and at the bottom is a "back to the search results" link... the first item is the A1000

 

Aeromotive makes it.
Might want to get some 10AN fuel line too (thats what it needs).

Aeromotive also make some good regulators too.
You will be looking at either 13101 or 13109, the former provides 10AN inlets, the latter 6AN.

 

I think you should call Bob Kennedy at:

I know he used to be a KB dealer and installer. I bought his water injection kit and it works great.

 

When I was shopping around for a s/c I spoke with Bob but ended up getting the kit directly from KB. Once I get it back on the ole Mustang dyno and get some fine tuning done it should be good to go. I just wish I could find a replacement adjustable fuel pressure regulator. I've been searching the internet like crazy and can't find one. I'd think that one exists, I just can't find it. BTW, I have Snow Performance water/methanol injection on mine, it too works great.

 

These not suitable???

I have a Nordskog Digital Gauge. It is reading what KB is saying it should read at idle and WOT. Try calling these guys. Around here, everybody says they are the best. lonestarperformance.com

OK, just out of curoisity, what is wrong with all the adjustable regulators on the page of the link I posted from the summit catalog? Including the A1000 you were most interested in?

 

What's wrong with them is that they are not direct replacements for the OEM regulator. I'm probably asking a lot, but I want to be able to remove the OEM regulator and and drop in an adjustable aftermarket one in it's place. At this point I don't think one exists. I'm not even sure how you would install the ones that are on the link you sent. What would you do with the current OEM regulator? The regulator that is in there now is not much bigger than a PCV valve. If I were to try installing a regulator like the ones in the link you sent, what would happen to the OEM regulator? I've contacted Kenne Bell with my dilema to see if they have any suggestions but I haven't heard back from them yet. They only thing they did tell me is that I have a problem but not sure what would be causing my loss of fuel pressure. Overall, I'm off by about 5 psi at idle and 5 psi at WOT. I installed a new OEM fuel pump, fuel filter and regulator and still not seeing 32-35 psi at idle, I'm only seeing 27-28 psi. This problem is really getting me frustrated and pissed off. At this point I don't know what else to do. Thanks for the input though! I open to any suggestions.

 

does it stumble or run out of fuel under load?

 

Hey my Ft Mead Maryland friend

Read every word on this web page... I think it may pop on a few lights for you
