ZT-R Posted February 6, 2011 Share Posted February 6, 2011 (edited) Hey guys, i am plumbing my fuel setup but i cant seem to find a fuel pressure regulator with anything bigger than a 6an return. i have 8an lines going to and from the tank, running to a surge tank and 2 walburo 255 high pressures in the surge tank (surge being fed with 1 255 hp) with 6an outlet on each fuel pump going to each end of the fuel rail. i would like to keep the 8an size out of the return but cant find one bigger than a 6an... any of you guys have one? granted i have really only look at the aeromotive ones Edited February 6, 2011 by ZT-R Quote Link to comment Share on other sites More sharing options...
stprasinz Posted February 6, 2011 Share Posted February 6, 2011 isn't the port threaded? you could run the oversized fitting? Quote Link to comment Share on other sites More sharing options...
ZT-R Posted February 7, 2011 Author Share Posted February 7, 2011 right but you still would have a bottleneck... Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted February 7, 2011 Share Posted February 7, 2011 This (CLICK) regulator is the one I'm using. You can run any sizes you want with this bad boy.... Quote Link to comment Share on other sites More sharing options...

mark Posted February 7, 2011 Share Posted February 7, 2011 (edited) Run the 6 to 8 fitting on your regulater. It will work fine. Edited February 7, 2011 by mark Quote Link to comment Share on other sites More sharing options...

ZT-R Posted February 8, 2011 Author Share Posted February 8, 2011 between 1100-1245 @ the flywheel probably around 450 for now Quote Link to comment Share on other sites More sharing options...
sq_creations Posted February 8, 2011 Share Posted February 8, 2011 This is what I put on a lot of high power 4 cly. It can run a base pressure of 100psi. http://cgi.ebay.com/ebaymotors/Weldon-A2040-series-bypass-regulator-up-120psi-fuel-/220733382119?pt=Motors_Car_Truck_Parts_Accessories&hash=item3364bc1de7 Quote Link to comment Share on other sites More sharing options...

Snailed Posted February 13, 2011 Share Posted February 13, 2011 (edited) The regulator IS a bottle neck. If it's getting fed by two 255lph pumps a 3/8 fitting at the regulator won't matter. Edited February 13, 2011 by Snailed Quote Link to comment Share on other sites More sharing options...
