Hay guys I have a 25det neo with s2 and s2 shit on it any way iv wired neo coils into s1 loom and that's algood neo cas is working when u spin it the injectors are doing there thing but still no go but iv noticed I removed reg of rail but left feed line attached then turned pump on and nothing comes out of the reg at all the feed line just goes rock hard.. is my reg stuffed or is the walbro pump not enuf to open it?

You sure it's plumbed the correct way around? If the pump "wasn't enough to open it" how would the feed line go hard with pressure?

fuels coming up to the reg and that's as far as it gets an stops there. Yea the feed line is on the reg and the reg is unbolted from the rail an no fuel is going thru the reg I unbolted it because I removed the return an no fuel was coming out of it so rail was empty and dry that's what made me take reg of with feed line still attached to try it.

Sounds like a plumbing issue. Are you sure it's plumbed correctly?

[r33terror]

Yea they are round the right way cause I removed that feed line and blocked it with my finger with pump on this morning to check pressure and I could bearly stop it. The returns got it's own reg too , the one that's on a bracket on the tower from factory. It just beyond me that the fuel wont pass thru the reg to the rail

The fuuel flow is to the rail then the reg, which is why I have suggested the plumbing error.

[r33terror]

Ayyy? so the reg on the front of the rail is a return and the rail feeds from the rear?

[r33terror]

My feed is at the front and return at the back there 

[Ben C34]

That's backwards, feed goes into the rail, return is out of rail

[r33terror]

So does return have 2 regs ? The one on the rail at the front and one on the tower bracket? Shit that reg on the front must be a one way thing... So the feed line with the filter on goes on the rear of the rail by fire wall end???

[Ben C34]

Yes, now you have got it.

the other thing is a damper, not a reg. Never knew it was a one way valve as never plumbed one up backwards!!

[r33terror]

Haha I put my reg on off the return of my spare neo top feed rail cause I could blow thru it but it would make any pressure and ran only at 200rpm lol thanks mate I'll try the change over tommoro after work lol
