evandostert Posted December 9, 2015 Report Share Posted December 9, 2015 My fuel pump is on it's way out. More power should be needed this summer. Thinking front mount turbo or small maggie planning AEM 320 fuel pump http://aemelectronics.com/products/fuel-delivery/high-flow-fuel-pumps/320lph-e85-compatible-high-flow-in-tank-fuel-pump-offset-inlet New stock regulator, rails and fuel filter. Anyone here have a 320 pump in a stock return system??? Would it overpower the stock regulator?? Quote Link to comment Share on other sites More sharing options...
rcapone Posted December 9, 2015 Report Share Posted December 9, 2015 Most guys here use the Walbro pumps, including myself. I have dual 255's and some even have dual 450's. Why AEM? Quote Link to comment Share on other sites More sharing options...
evandostert Posted December 9, 2015 Author Report Share Posted December 9, 2015 Trying to keep stock rails and regulator. 320 looking like the largest before stepping up to aftermarket regulator and rails. Then i am in it for another grand between rails fittings regulator Quote Link to comment Share on other sites More sharing options...
rcapone Posted December 9, 2015 Report Share Posted December 9, 2015 (edited) ok, I see. When I bought my tvs 2300, the kit came with a single walbro 255 and I think 45lb injectors but retained the stock regulator (stock return-less style system) and was good for about 12psi. I know everyone I spoke to recommended Walbro, including Zippy when I went to upgrade to a double pumper return style because I wanted to go faster. Honestly, I'm not sure you'll even find anyone on this site who runs AEM, so you may want to check some other resources to who are familiar with their quality and reliability if you can't live without AEM for some weird reason.

kaze_v8 Posted December 9, 2015 Report Share Posted December 9, 2015 Im running, AEM, but ive got a 340lph. Quote Link to comment Share on other sites More sharing options...
zachm89 Posted December 10, 2015 Report Share Posted December 10, 2015 You should be alright with that pump without over powering the stock FPR. According to their flow chart it won't actually flow 320lph @ our base fuel pressure. Their 320lph rating is @ 43psi. 58-60psi it'll be somewhere in the 280-300 range. I also run Walbro pumps so other than what AEMs website says I dont have any other info or advice for ya. Quote Link to comment Share on other sites More sharing options...
