Thanks for the response, I decided to go to the dealer yesterday and purchase a new regulator kit, I was surprised to find what was wrong with my truck! I totally see it as my fault for not looking but a year ago when I updated to the blue spring I just purchased the spring not the kit, changed the spring and have been running it ever since. It was missing the O-ring or seal that mounts to the plastic sleeve in the housing. My truck has always run great no issues except for bad fuel mileage that was why I decided not to long ago to purchase a fuel pressure gauge to see if it was a possibility, Looks like that was my main problem! I fought with it for weeks new filters, replaced the pump, I even added the bb to the blue spring that was when the pressure gauge would read 0 then slowly climb and hold but without the bb it would be a steady 40-45. Last night once I changed the complete kit that I cheeped out on the first time the pressure sored to 70psi with just the key on and even stayed there once the truck was started and at wide open throttle it still only drops about 5psi. Finally it is working the way it is supposed to! But now I am even more concerned! How has my truck rum ok for this long on low fuel pressure? It has been more than a year! I changed the spring a year ago and the thing was installed wrong from the previous owner! It has been running this way for over 2 years! When I got the truck I got 14-15mpg city and 17-19mpg highway, I have only been getting 11-12mpg for a while!
Are my injector shot now?
Would this have done damage to something else?
Should my mileage improve?
Thanks for any input, I needed to find this out! I spent almost $9000 in fuel last year!
