Does anyone know if it is possible to modify the stock fuel rails on a 2000 Accord V6, to a looped fuel flow to help with the "Heat Soak" problem? Can the right side ends (passenger side) of the fuel rails be drilled & tapped, so one could loop the fuel flow? In looking there appears to be some type of plug (?) in the fuel rail ends. It would be tight with the proximity of the PS pump, but probably doable.

Also, what size line would be required - I would assume it could be small, like ~ 1/4", just enough to allow a loop flow?

Is there any after market rails that might work? I would like to keep the OEM fuel block/ FPR set-up.

I have read Dagle's modification and have not found those parts (excellent modification). Any thoughts and assistance is appreciated. Thanks

 

Is "Dagle's modification" the one where the rails from Ody are used?

Also, for giggles, have you installed a new OEM thermostat recently. I've read where some have had luck with doing just that.

 

Poorman212, Thanks for the reply. The two best threads to address the 2000 Accord V6 heat soak issue that I have found or been directed to are: hondaaccordforum, jester1020 "Accord V6 hot soak fix"and honda-tech forum, dagle (I do not recall the thread title). Both of these use other Honda fuel rail systems from the Odyssey (99-01?) or Accord (98-99?).

There are a number of recommendations that deal with the coolant system, reflective heat wraps, FPR/PCM, etc. I have not tried these and think the looping of the fuel rail is the best try at a fix. I have parts on order to try!

I am still curious as to if the Accord 2000 V6 OEM fuel rails right ends can be drilled/tapped for fittings & a short hose to complete the fuel loop - this would be quick, cheap, and dirty (ahh - EricTheCarGuy).

 

Well there is always the first

Yes, I've read the one on "hondaaccordforum" before and that, I'm more active on there than here.......sorry just my opinion but too much BS here.

You have the car and can "see" better than me. I'm one that would try to sneak up on it. If you drilled and tapped an 1/8 pipe thread into the ends of the rails (pipe is best for sealing liquid). Then with Fuel Injection fuel line with the correct clamps, you might get enough flow to overcome the "heat soak".....?

Again, a new OE thermostat is not that much money and as I stated some have reported that was enough to get the issue to go away. As I'm sure you are aware this "seems" to show up more when the "winter blend" gas is being sold....seems to have a lower boiling point....but what do I know.

Either way of whatever you decide to do....I'd like to know how it turns out as more knowledge is always nice.

Good luck.
