The presure gauge jumps up and down spasticaly if over 20lbs is set.

OEM fuel pump replaced with Apexi GTR but same problem.
This happens on idle with RC-Eng cleaned 850's but PFC settings not changed.
I can't remember the shop I got it from and I can't go back far enough on ebay or paypal to find out but I know he said he got them from Japan. I suppose it's possible it could be a chinese replica since their are chinese Walbros replicas. Well Sard has a USA office now but will not warranty purchases from Japan. I tried to use Rotaryextreme but they don't have an account with Sard USA. I will try a new one tomorrow but is it possible that it could be connected wrong and/or something else could be the problem? I beleive she is runnign lean because the black heat coated exhaust manifold is glowing red like bbq charcoals.

I have the small size and I know I will be at it's limits or just under (550hp max) but this problem is at idle. I can feel my hair turning grey as I type!

 

Dammit man I want to get one of these your scaring me!!

 

Well just buy it from Dynamic Autosport, that's where I bought the replacement from. They are an authorized reseller for everything. I've never heard of one failing and it's supposed to be the most popular FPR in Japan. Allthough I am worried about using the small one. On ROtaryextreme they claim it's good to 550hp but on ebay and I think Takakaira also it says 450hp. That won't cut it for my setup and i'll have to buy the larger one for $100 more. The best thing about it is being able to still use the stock fuel lines. If it's the regulator then i'll post again tomorrow.

 

aeromotive never fails..at least with me

 

^ A'motive requires new fuel lines and the Sard allows you to retain the OEM rubber lines. Since i'm kissing the smog laws *** and trying to make a semi stock sleeper I will try another one. I've never heard of a Sard failure before and they claim they have never had a return before. I'm not trying to start rumers and every start saying they are bad just because of this thread. It could be bad, it could be a chinese replica, it could be something else. I am out of money and my tune session is next friday, so i'm almost out of time to fix this or choose driving to Texas or go with XS.

 

Purchased a new one and now it will hold 60lbs &> or 20lbs &<. wtf is up with that, uhg?

 

Update:
M'trix had the fuel lines wrong and it holds pressure fine now.

 

now i know where NOT to bring my car...thanks for the input and the update.

 

Well, at least they only charged you like 10 grand to screw up your car

Glad to see you got your problem fixed
