Dropping the fuel tank today

Another

Jimmy, I tried blowing through the line. I couldn't blow air through. What in your experience stops the flow? A clog? Or where it couples to the tank. I'm assuming that it returns to (what I think is) the reservior tank above the actual gas tank. I assume that the procedure is to drop the fuel tank ...

Thanks for the feedback Jimmy. It is relief valve that is preventing the pump from failing, then. Would this affect the tank's pressurization? When I turn the gas cap, there is no hiss and so I assume no tank pressurization. My father suggested something similar but I didn't execute it very well. I ...

I have two lines coming across the valve cover, but one is the fuel supply and the other is vacuum line 1 in the picture, it runs to the intake manifold.

I'm guessing it is a later year.. maybe this is an intermediary between the FPR on the rail itself in the 850 and what you describe, at the tank, in the XC70.

Is it the same case if it is a return system?

Thanks for the feedback. I ordered the FPR from FCPeuro. Its behind the block on the passenger side for this model. I got a different FP tester from O'Reilly tonight and tested again to be sure. Again ~96psi. I'm in Corpus Christi, TX... the closest dealership is 120mi away in San Antonio and there ...

I had a successful repair and saved a bundle. Nice write up. Thank you.

I have a persistent p0171 code on a '98 V70 AWD B5254T--long term fuel trim bank 1 lean, at something like -23% to -25%. After checking for vacuum leaks and doing a homemade smoke test, I decided to check fuel pressure. Performance on the car is NOT too severely affected--little hesitations and surg...

Well that's pretty simple. Thank you! It does, I did not want to proceed without knowing where it belongs.
