Stock FPR ??

[killerrudy]

I was curious if the stock FPR was able to manage pressure with a larger (walbro 255) fuel pump? My DSM had a horrible time with keeping control of the added pressure. Thanks.


Yeah yeah yeah I know all the DSM jokes already.

To be honest with you I haven't heard of anyone upgrading one without upgrading the other. Being you are in Calif I would order a AFPR from Mike at RPM. HTH

Brian, Sorry for the late reply. I would upgrade the FPR while I was there. I wouldn't want the fuel pump to over work the stock FPR or try to find out if it will? And if you need help installing the racetronics kit let me know. Its very easy and I can walk you through it.
See ya,

Stock 237 regulator will be fine with a 255L in-tank pump. I used a stock 237 with my Weldon pump, which flows considerably more than 255L, and had no issues with pressure creep.

To answer your question, the stock regulator will keep up just fine with a 255. If you were running a pump capable of supporting say 800+ hp like a weldon 2035 then you would need a larger regulator and return line in order to keep your base FP down.

The benefit of the adjustable regulator is the base FP adjustment. You can make 600+hp on a stock regulator if you want, you just need to adjust the fuel map in the computer. It still rises 1:1 per pound of boost like the aftermarket.

Many people just replace the pump with a 255 1) b/c it is cheaper then a stock replacement and 2) adds fuel volume to an already undersized stock pump. You only need to change the regulator if you want to alter your fuel map.
