How much spect must be full pressuer on this car
Expert:  Alex Olsen replied 9 months ago.

you should have at least 50psi at full throttle, have you replaced the fuel filters?

Customer: replied 9 months ago.
No I never replace full pump. but why the engine working when I start car easy. but when I accelerate gas pedal the car smoke a lot gas from pipe but never die still running. I test drive car is hard to go even 30 miles but on idle is working ver good
Customer: replied 9 months ago.
But full pressuer drop a lot in acceleration gas pedal
Expert:  Alex Olsen replied 9 months ago.

yes have you replaced the fuel filters?

Customer: replied 9 months ago.
I replace the new full filter and check my primery pump working good
Expert:  Alex Olsen replied 9 months ago.

ok if you have replaced the filter then it sounds like you have a restriction in the fuel supply line,

Expert:  Alex Olsen replied 9 months ago.

minimum fuel pressure at idle is 45psi could also be the fuel pressure regulator at the back of the head

Customer: replied 9 months ago.
Ok what I must do to fix that so my full pressuer not stay 20 psi and not drop to zero
Expert:  Alex Olsen replied 9 months ago.

i would check the pressure regulator, it is on the return line on the back of the rail

Customer: replied 9 months ago.
Do you think that is reason my full pressuer goes to zero whe I accelarate gas pedal. Car not go more than 30 miles in full throttle. Do you think full pump is weak cause this problem or pressuer regulator in back is bad
Expert:  Alex Olsen replied 9 months ago.

i world check for restriction in fuel supply line

Customer: replied 9 months ago.
How I can fix this restriction in full supply line what I must do to fix this problem
Expert:  Alex Olsen replied 9 months ago.

try running the engine off a alternate fuel source, attached is the performance diag sheet

Customer: replied 9 months ago.
There is no other way to fix this restriction full line I donot get this part. this is mean there is something goes in side line and stuck there then the car doesnot have power in accelat full throttle
Expert:  Alex Olsen replied 9 months ago.

no you can fix it but by running on an alternate fuel soruce you will see if that really is the problem before you just start replacing parts it could be something stuck in the supply line or something in the tank

Customer: replied 9 months ago.
Ok Alex Thanks I go open all full line and every thing start clean them and put them togather but I donot have for restriction any tools. Is there is other way to get out this restriction from line out accept the way you show me now .
Expert:  Alex Olsen replied 9 months ago.

you could pull the line off the filter head and tank and blow air through it

Customer: replied 9 months ago.
