i have had this problem before when i replaced the stock fpr. what happened was i left the black plug in the fpr hole that goes to the rAIL. my guage read about 75-80 psi. if its not that and the fprs are messed up i have a stock extra that i will let go. let me know.

 

im using a 255 walboro pump but it was the same situation before i put that in. this is the really odd part. the weapon r fpr that i had on which mounts after the stock fpr was reading 41and when i adjusted it it would go up or down accordingly but when test at the filter the way they tell you to check fuel pressure its at 80psi. i tested 2 of my buddys x's and civic and both of theirs read 35-40. by the way my car is an 91 crx if i didnt mention it yet

 

i guess since its not leaning out anymore i wont worry bout it but any other feed back is appreciated.

 

mabye a pinched fuel return line somewhere?

 

ok these are the things i know its not. its not a pinch return line cause i ran the hose of the rail into a bucket and its not the fpr cause ive tried 4 different ones including one stock one that was on my boys x and read fine.what else could it be

 

how about a broken pressure guage? lol

 

guage reads much lower on other civics and x's on the same day so i dont think the guage is broken. not unless its a magical guage that just dosent like my car
