Another benefit of the turbine design.

So looks like my fuel pump failed last night on way home.... Any recommendations on replacements? - AKS4 2014-10-28 14:52:11 (1861 views)

  - Injector body's leak, and the leak at at connector too. - stew 2014-11-02 13:46:22 (1312 views)
    - Yeah, Cyl 1 is leaking at the fuel rail tho. I am on my second set of orange/pink top OEM injectors - AKS4 2014-11-02 19:25:58 (1326 views)
      - Maybe the cup on the fuel rail is out of round. - jprice 2014-11-03 09:44:40 (1284 views)
        
        I have been leaning that way. It was fine during summer but now that the cold is setting in - AKS4 2014-11-03 15:28:18 (1288 views)
- Dw300 is like 150 and walbro450 is 120 so upgrade - DxC 2014-10-30 10:01:47 (1363 views)

      - Every graph I have seen show over 15 amps 400 and 16+ amps for a 450 at 4 bar. That's at 13.5 V  -  slow ride  2014-10-30 11:32:03 (1370 views)

        That's fine so was I (listed both). Actual results are always good to know, but I just wanted data.  -  slow ride  2014-10-30 15:02:03 (1322 views)
        
        4bar is at egine running in full throttle NA mode, which means at 0psi of boost. Once you hit WOT  -  julex  2014-10-30 14:38:36 (1395 views)
        
        Care to link one of those posts? All I have found is discussions on how our FPR is a bypass  -  AKS4  2014-10-30 15:02:43 (1329 views)

        No, I was questioning how it would be pegging the FPR when any excess fuel is getting returned  -  AKS4  2014-11-04 12:54:54 (1303 views)

        FPR overrun at idle conditions was one of my other considerations. I listed the 400 and 450  -  slow ride  2014-10-30 14:57:31 (1345 views)
        
        Should be close enough for trims to take care of it...  -  Mike2k2S4  2014-10-30 15:46:26 (1334 views)
        
        Good info. Do you monitor fuel pressure? Trims can take care of a lot of stuff, but not ideal.   -  slow ride  2014-10-30 15:52:10 (1320 views)
        
        Not ideal... hence the tuning. But I think it'll be well within 5%.  -  Mike2k2S4  2014-10-30 16:00:56 (1325 views)

        Man, better tell that to my stock 15A fuse. It clearly didn't get the memo!  -  Mike2k2S4  2014-10-30 14:41:28 (1362 views)
        
        I'd be curious what the voltage to the pump is with the stock wiring. Hell a 255 will cover stage 3  -  slow ride  2014-10-31 08:05:00 (1318 views)
        
        Good old painters tape the gauge to the windshield. I'm guilty as charged also haha   -  slow ride  2014-10-31 07:58:46 (1298 views)
    - I know you can rewire to the lid, but I'm talking about the factory wiring connector on the lid. - slow ride 2014-10-30 08:33:20 (1343 views)
  - Ordered one up, only ~$115.. Thanks for the tip on another fuel pump option for us. - AKS4 2014-10-29 19:55:14 (1327 views)
  - I take it with the old clamp is to keep the pump "up", as it must be installed from the bottom - AKS4 2014-10-29 13:12:24 (1343 views)

      - Good info all around on that pump. I didn't know of that one before. - PKmode 2014-10-29 19:25:40 (1338 views)

- Fuel pumps are easy and quick to swap, why not just save money for now and buy a used stock pump... - Roger (on the road) 2014-10-28 19:23:15 (1392 views)
  - This is a great option and everyone should keep a stock, used unit on hand - jakecro [ww] 2014-10-29 00:23:37 (1365 views)

    - Yea I hear you - CTAudiDriver 2014-10-28 17:19:10 (1385 views)
      - Walbro 255 is fine even for stg3. - PKmode 2014-10-28 17:41:36 (1355 views)
        
        Would a Walbro 255 be overkill for stock fueling ATM? - AKS4 2014-10-28 18:43:38 (1370 views)

  - How difficult was it to install a non-OEM one? - AKS4 2014-10-28 17:05:26 (1334 views)
    - 034 kit wasn't too bad. Be sure to run the tank low before the install. - Avantugofast 2014-10-28 18:45:35 (1341 views)
      - Good to know, Unfortunately as the car will not start I'll be siphoning the fuel out (1/2 tank)   -  AKS4  2014-10-28 18:48:18 (1333 views)
        
        no need to do that just be careful and have a catch pan ready   -  Beerock  2014-10-28 23:14:26 (1323 views)
        
        Siphoning the fuel takes only a little time and makes the job *much* more pleasant.   -  bingS4  2014-10-29 06:48:08 (1339 views)
        
        Or you could just disconnect the pressure side at the motor and let the pump do the work.  -  PKmode  2014-10-30 17:36:28 (1312 views)
        
        not when you get a mouth full of gas thats always a risk   -  Beerock  2014-10-29 22:56:01 (1317 views)
        
        Well, that's a dumb way to siphon gas. Spend $3 on a bulb hose.   -  bingS4  2014-10-30 06:52:59 (1334 views)
        
        Yeah, and I already have an inline drill pump and hoses from another project, so should take no time   -  AKS4  2014-10-29 13:27:11 (1317 views)
        
        Also, set up a fan blowing fresh air into the car when you're working on the pump. Don't have  -  bingS4  2014-10-29 14:59:35 (1333 views)
        
        You shouldn't use a drill pump for flammable liquids. Drills create spark when running.   -  jprice  2014-10-29 14:11:35 (1322 views)
        
        Mine is the el-cheapo all plastic one, so I didn't think about sparks. Might rethink using it..   -  AKS4  2014-10-29 14:15:20 (1325 views)
        
        sparks are from inside the drill. :) Look in the vent holes when you operate it.   -  jprice  2014-10-29 14:24:42 (1327 views)
