Picked up a Silly Rabbit fuel system!




Overview of everything. Rails, baskets, fittings, and wiring to connect into the stock harness.





Close up of one of the rails, it's a work of CNC art!





Top plate with vent showing the MILspec wiring connector.





Bottom of the top plate, return fittings, Wiring, and fuel pump plumbing.





More art! Check out the pump holders, wow!





Pump holder again, complex and very well built!





wiring connections. The round one is MILspec pinned connection, the other is a 3D printed connector with some really nice heat shrink sealing it up for connection to the stock harness.


Hopefully those aren't too big, doing this on a tablet Guys this is a really nice setup and I'll document it as I install it. Mine is full boat, two big E85 pumps, compatible lines, and good sized injectors. I'll try to document the install but it will be a little bit before I can do it as my car is still in stereo jail and I have an exhaust to install first too. The plumbing is all black anodized push-lock and the hose is the black braided stuff that won't scratch everything around it. I haven't fitted it but looking at it I'm seriously impressed at the level of craftsmanship. If you need a fuel system SRM has got quite the setup, and it's got options for levels of performance.

If anyone has questions or wants to see additional pictures let me know and stay tuned for the install!

Looks AWESOME!!! So are you running dual 8AN to the rails? Or is that 6AN? Hard to tell. Is one of those pumps staged or do both full time? Super nice stuff!!!

I will have to check on the line sizing, I've not yet laid out everything to figure out which goes where but have been mostly marveling at the craftsmanship. The pumps are going to be setup to run together at least initially. I know there's a chance that the two of them together may overwhelm the return. The Fuel Labs regulator should flow well enough to handle it but I'll stage them if I must, I've done that on other platforms to solve return flow issues. Not too many of these have gone out the door so I'll be trying to document how it goes together for others. I've certainly got the right parts for a very clean install!

Unobtanium exhaust goes on first, I'm dying to hear it. UPS managed to damage it on the first round and Chris is repairing it for another try. Intercoolers, Y-pipe, and possibly one or two other tweaks and then it's off to Garth for tuning!

This setup runs 2 X -6 feeding into a single -8 inline filter, then splitting again to 2 - 6 feeding each rail individually with a single -6 return. This fuel system supports up to 1178whp on ethanol (same setup on a GTR). I am running upwards of 900whp on my car with a base fuel pressure of 30psi (55psi WOT) on 2000cc injectors which are only at 70% DC right now.

^^ yeah that lol! I saw the Y fittings but didn't want to dump everything out and lay it out. For. My purposes this is almost certainly some overkill but I wanted to be E85 compatible all the way, needed much larger injectors, and to flow this much fuel I needed new rails as the fittings to the stock ones are restrictive with this much fuel. Wish everyone could see these rails in person, very nice! IF I've not got this installed by the time I head to Pocono I'll bring it with me so that everyone can take a look at it up c,one and personal!

Very awesome!!! All kinds of work of art!! I should be getting my Stage 1 this week (Thanks Sam). Eventually installing the rest of Stage 3 parts after a few road racing sessions this Spring. She will be down for a few after that to install more goodies. I am very thankful that Sam and SRM decided to tackle this project.

Let me know when she is back from Garth, would love to meet up and check out the build.

The attention to detail is pretty seriously nice. Prior to this I was looking at booster pumps and other things I really didn't want to do in order to bump flow, I think this is a much much better solution! The only possible concern might be too much flow but my injectors are small enough I ought to be able to idle them okay with decent pressures. Staging them would be easy enough to do if needed. Hopefully it won't be too painful to install, waiting on a little warmer weather and getting my darned car back. I'm going to try and get the DME flashed for the larger injectors and MAFless so I can get it to Garth and pass emissions in my state. Without rods I won't be pushing the limits of this setup but I'm future proofed for sure!

Ive got one of Sams systems coming but im going to run the -6 lines to each rail with a dedicated filter for each line and a dry break coupling on the feeds and returns.

Dry break couplings might be an interesting upgrade but I'm not worried about line sizing. If anything I'd change it so that I'd only have to run a single line back not because of capacity. I don't anticipate problems though since this has already been installed in a few cars with no issues. Honestly if anyone wants a serious fuel system I see no reason to use anything else at this point. If someone wanted to get realllly crazy maybe a third pump? I think the limits will be the siphon tube octopus in the tank and perhaps the E85 sensor being overwhelmed but mine is going t otake -6 so I believe it will be okay. I'll need to source a pair of push lock for that but otherwise the system is complete. Really love this hose too as it's nice and light and doesn't give me splinters, at least not yet lol. The covering feels like it will be easy to work with, certainly better than stainless IMO.
