[QUOTE="Black306, post: 7614455, member: 4780"] I posted a couple threads where I wanted to buy a PPRV on a couple sites and only 1 actually contacted me (that's the one I'm waiting for). I think anyone that has already pulled the PPRV couldn't care less about a modded PPRV and would rather simply throw it away than bother mailing it out. I believe it's only a select few that are truly interested in my modded PPRV idea, and these are the people that will hold on to their PPRVs to see what I come up with. The rest are happy with a typical PPRV delete, so long as it doesn't damage their FRPS (people experiencing damaged FRPS' seems to be the minority). In light of my more recent discovery on how the PPRV works (ie no actual "blow off" function), I think the easiest solution that will satisfy most people would be to go with a PPRV delete, tweak the fuel tables to minimize pressure spikes, and increase the duration for the pump cycle at key on/engine off to help with startup. If my theory is correct that the small hole in the nipple is a pressure limiter or pressure spike reducer, and someone is still popping FRPS' after optimizing the fuel tables, then simply drilling a tiny hole in the "Y" fitting should do the trick. Eh, but we'll see. I'm still interested in what will happen with a stock PPRV. PS. On a side note, I personally don't understand how people can feel comfortable with the use of 3/8" hose for a PPRV delete. First, the nipples on the pumps and hat are closer to 5/16", and the bends the hose must make actually start to kink 3/8" hose. So, people risk having the hose ends come off or leak at the pumps and/or hat, and a kinked 3/8" line would probably flow as much, if not less than an unkinked 5/16" hose. Even without the problems of fitment and kinking, there should be no significant advantage of going with 3/8" hose instead of 5/16" hose. The restriction in either case would be the fuel filter and fuel line leading to the rails. If someone were going through the trouble, or had a need, to replace the filter with a high-flow version and modify/replace the restrictive fuel line, a Fore hat would probably be the better route anyway. My suggestion, use H209 30R10 5/16" hose and a "Y" fitting from McMaster-Carr (part# 2653K19) or LFP. OK, time to get off the soap box. :laugh: [/QUOTE]
