i had this sard reg on my old fuel setup with just one 044 but now i got two 044 fuel pumps feeding the rail, the motor has just been built so when i goes in for the run tune i dont want it to be over fueling the motor or something else that i could of fix before the tune... so does anyone else have one of these regs with a big fuel system to know if its to small... cheers..

put a fuel pressure gauge in there and see with the reg adjusted to the lowest setting and see what fuel pressure you get, this will be the minimum, aslong as this is less than ~30psi it'll be fine. obviously dont run the motor if your not ready for that, just let the pump prime a few times

Definately too small - will overload reg at low loads. Use a pressure switch to turn the secondary 044 on at high boost and you won't have any issues with pumps overheating or fuel pressure problems.

If you switch one pump on and off, be sure to install a non-return valve on the suction side of that pump...

Two 044's are alot of fuel... especially if you try and squeeze it through a small return oriface (sard reg)

To help stabilize fuel temps and return pressure, I will be running a FPR with a -10 return outlet and -10 retun line on my next set up (1400hp aeromotive pump).

This is the reg:

I also need the muliple outlets for nitrous, 2 fuel pressure transducers and an accumulator.

Hope that helps

I ran one of these regs with 2 x 044's for years...never a problem with lack of return flow...we even measured flow rates and pressures at idle...rock solid.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
