All right, to keep it short Im setting up -6 AN lines for fuel on my friends 2g DSM AWD and we are trying to find a clean way to mount the AFPR so that we can still see the gauge and kinda show off the nice "shiny racecar parts"

So if anyone has pictures of where they mounted their's it would be awesome!

Also I am still figuring out how I will be mounting the lines under the car. Id like to route them together and use the original brackets from the car but I dont think that will be possible, since they seem too large... Any ideas ?

I got a couple more fuel related questions I'll make another thread about it just to make it easier to answer.

Thanks!

Also, the car has no AC, NO EGR , NO EMISSIONS stuff and NO CRUISE CONTROL

Here is mine. I suggest buying a rivet nut gun as they are handy. One of these holes is factory other is a rivet nut I installed.

Not the most elegant of bracket but I used what I had. Better versions exist.
I'm not a huge fan of the 180 in the return line either so I'm probably going to change that up myself too this year

Here is a different mounting look if you need to lay it horizontally.

Do you have any more pictures of how it's mounted? I like this idea, just not seeing how it would work with the fittings radian supplies.

Are there any other direct mount fpr options out there? I seem to recall an old school adjustable fpr that mounted directly to a dsm fuel rail.

I have a few of these and they are what's up. It checks every box. Surprised the concept didn't catch on and evolve.

That is a BM (I think) top hat on a stock regulator. It's easily 20-25 years old. It can only raise fuel pressure above stock, never lower, which was the whole idea of us using an aftermarket regulator. I bought one at the shootout 5 years ago for 20 bucks for kicks, never used it though.

If I recall correctly, the issue with that type of afpr is it only allows you to increase fuel pressure, but you really need something that lets you decrease it when using an aftermarket fuel pump. Having said that, anyone ever try to shorten the spring to allow for adjustments to decrease fuel pressure?

With a larger pump, a regulator needs flow to lower pressure in addition to a spring adjustment. With the stock regulator, the spring was irrelevant because the openings in the regulator and the opening in the return siphon in the tank were so small, the larger pump was flowing more than the openings would allow - causing back pressure.
