Hello, can anyone confirm the correct fuel pressure specification for a 2010 TL AWD

I have a manual that states between 57-64psi, how ever I saw on another website (DIY: Fuel Pump & Return Conversion with FPR - 7th Gen Honda Forum - The #1 Community for 2001-2005 Honda Civic Enthusiasts) that the regulator limits beyond 45psi.

I am having a bogging issue at full throttle or heavy acceleration, upon testing fuel, I thought I found my issue, since I tested it significantly below the specs that it calls for. How ever, now I am doubting I have the correct information.

Has anyone else ever put a walbro 255 in these cars? I noticed a write up someone did on here, but the photos aren't working any more. I am also getting a little detoured in doing this setup as, the link above shows you have to run a return line.

 

The SM I have also states 57-64 PSI under the hood by the strut bar, you have to remember that those specs are for the 2.4L 4cyl on the civic forums.

Replace the fuel pressure regulator.

 

I was under the impression that regulator made sure the pressure didn't go too high.

 

SM states to replace the regulator first if the pressure is not in the specified range. A mechanism inside the regulator could have failed causing low pressure.

If that doesn't correct it, you may need a new fuel pump

 

fair enough. I will weigh out the options. I haven't been able to find just the regulator except for on rockauto.com which is $170($200 dealer price), compared to the whole assembly which is $350, which includes the regulator. The silly thing is, if the regulator doesn't solve it, I would still have to buy the whole assembly, as Acura doesn't sell just the pump.

 

You trust what a "hack" writes on a Honda forum more than the official service manual for our car, an Acura?

 

If you read the original post, a walbro was done in an Acura here as well. Also, it wouldn't be a hack as Walbro has proven to build dead reliable fuel pumps for any application.

Acura has set procedures in their service manual for the ease of working on them(warranty work) and to make more money grouping parts together. This car would function just fine with an external fuel pump if it came down to it.

I do appreciate your post though, it has been quite a contribution to this thread.

 

I'm confused at what you're attempting to do so apparently I don't understand. I will add that it doesn't matter who's fuel pump you use, the stock ECU, sensors, and injectors are all calibrated to run at the stock pressure which is listed in the service manual. I misunderstood you to not trust the service manual for the correct fuel stock fuel pressure and take the word of someone on a Honda forum.

 

car-part.com has a few under a $120 in your area! Best bet is to look into a used one.

 

The main purpose of this thread was to verify fuel pressure. Which I was able to do.

The second part of this thread was to ask about the walbro Pump. I saw that it was done here: https://acurazine.com/forums/4g-tl-p...cement-891653/

The other link I posted I was mistaken, I thought for some reason that was the setup for a v6 Honda Accord, which I would have assumed was a similar setup.

I have decided against fitting a Walbro pump in my car, due to the fact that I would like to keep everything as factory as possible. I bit the bullet and purchased the whole fuel pump assembly online for $350. It was quite pricey, but it includes a new FPR.

As far as the used part, I am not confident in buying a piece like this used.
