msupra1 Posted March 16, 2015 Share Posted March 16, 2015 I ordered a Fuel Lab FPR -6AN inlet -6AN return port, and fuel pressure gauge. I'm also looking to order about 3 feet of -6AN stainless fuel hose, will this be enough? Now what I would like to find out about the fittings to put it all together, - what kind of fittings should I be getting for the fuel rail? I've read that they should be 90 degree bend. The outlet is -6AN but what is inlet size that bolts into rail? - I will need (1) -6AN to -6AN fitting to run line from FPR to rail ?

msupra1 Posted March 16, 2015 Author Share Posted March 16, 2015 anyone running fpr with stock rail? Quote Link to comment Share on other sites More sharing options...
chrispot Posted March 16, 2015 Share Posted March 16, 2015 firstly why do you want a aftermaket fuel pressure regulator? i would not bother if on a std tt bpu or not. you will need a adaptor as the oem fpr has a flange and stub with a oring, have a look on ebay they have them on there. regard chris Quote Link to comment Share on other sites More sharing options...
msupra1 Posted March 16, 2015 Author Share Posted March 16, 2015 The car is single turbo running a 400lph pump and SARD 800cc injectors, and it will make near 700bhp, I was told by my tuner it does need a FPR. Quote Link to comment Share on other sites More sharing options...
Darren_Whifbitz Posted March 16, 2015 Share Posted March 16, 2015 You can use a push in fitting in place of the std reg , and i would also get rid of the std fuel damper . Use -6 pipe for feed and return Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted March 17, 2015 Share Posted March 17, 2015 I sell a kit, see here http://www.garagewhifbitz.co.uk/toyota/supra/fuel-parts/garage-whifbitz-1639.html Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted March 17, 2015 Share Posted March 17, 2015 And fpd removal pipe http://www.garagewhifbitz.co.uk/toyota/supra/fuel-parts/garage-whifbitz-825.html Quote Link to comment Share on other sites More sharing options...
msupra1 Posted March 17, 2015 Author Share Posted March 17, 2015 Ahh too bad I didn't see this earlier. I have already ordered some fittings and some -6AN line, and was planning to just get everything else locally. The kit would have made it less of a hassle.

Wez Posted March 17, 2015 Share Posted March 17, 2015 I was told by my tuner it does need a FPR. Since know one else has asked, why does it need an FPR? Are you raising the fuel pressure as the injectors are maxing out? Quote Link to comment Share on other sites More sharing options...

np89 Posted March 17, 2015 Share Posted March 17, 2015 If you feel you need an aftermarket FPR, then you obviously need bigger injectors as this is the only reason you would need an aftermarket FPR. The Std Toyota Reg is more than capable to cope with 700bhp. Aftermarket FPR's are used to Circumvent the issue of poor fuel delivery either due to restrictive fuel lines or insufficient injector capacity. Your tuner is a moron Quote Link to comment Share on other sites More sharing options...
np89 Posted March 17, 2015 Share Posted March 17, 2015 p.s I know this because my car is running a near identical setup and power and is fine on the std Reg Quote Link to comment Share on other sites More sharing options...
np89 Posted March 17, 2015 Share Posted March 17, 2015 Also what you should check is that if your car is running a standalone ecu, that the fuel pump has a direct 12v feed as it will only run 9V through the std fuel ecu and if your tuner thinks it is running lean then this is why because my tuner made exactly the same mistake and tried to crack I needed all this extra fuel system balls and I didnt need any of it.

msupra1 Posted March 18, 2015 Author Share Posted March 18, 2015 I think I would know if I'm running a standalone ECU haha It has an AEM V2. I called my tuner and he recommended that I get it as it will be easier to adjust fuel pressure. Luckily the FPR doesn't cost that much. I have a shop that handles my upgrades and another shop for tuning. If my personal Supra mechanic feels the FPR is not necessary I'll just sell it off.

That is exactly what it is for and is only required if you plan on increasing the fuel pressure over stock levels, the main reason for doing this is to squeeze more out of the injectors instead of replacing them with larger ones.
