Sounda like a big PITA over a deng fuel pump setup. I can't believe that nobody has come up with a solution for those cars yet.

Mine works fine...ya know, when my car works lol.

edit: for going straight

Not sure if BlaqOPs mods the return or not. Gotta keep in mind that an Aeromotive 340 flows over 425lph at low pressures. That single pump flows about the same as a double pump at full honk.

The other pump on a blaqpops isn't another 255 though, its a mustang gt500 pump or something that flows a lot from what i understand.

Regardless, ya those flow a lot.

It is ~280lph pump and it is Walbro-brand. I looked it up when I had it. IIRC they scored lower numbers than Buschur in that test.

Buschur doesn't care about anything but going forward, either.

**Murlo26** · 05-26-2011

The one in that test was just two 255's I believe. He brought the bigger pump into the equation for the X because it has the same dual voltage setup as stock I thought. i could be wrong but who knows.

Regardless, I am always amazed at the new/different problems your fuels system has.

Eventually, everyone will be using your testing/knowledge to design X fuel systems, i applaud you.

I appreciate your positivity. As you can imagine, I find it hard to remain optimistic in times like this.

**Murlo26** · 05-26-2011

Trust me, I know what you mean...spending kilobucks on cars over and over gets old, I know.

Look on the bright side, through all this, you have always been able to drive your car.

**mlomker** · 05-27-2011

I was able to confirm that the hanger return is the problem. The one used thing that I buy (fuel hanger) and it has a problem. Go figure.

Now I'll have to find a source for that black slinky hose in the hanger for the return...they snap on so can only be used once. grr.

**Kracka** · 05-27-2011

Would a rubber fuel hose with hose clamps work?

I've heard from people that have tried and they say it invariably kinks up due to the angles. 30r10 isn't cheap either so if there's a source for a new plastic line then that'd be a better way. I have an email off to JRZ Tuning, who was able to get one for someone.

It isn't designed to be hose-clamped back on but I'll eyeball it when I cut it off.

**Kracka** · 05-27-2011

What's 30R10? I assume that must be ethanol-safe fuel hose?

Yeah, even the single foot I picked up for Scheides on my discount was $14.

**mlomker** · 05-27-2011

woot! Home where she belongs. I guess I lucked out on the days that it was out of service...I had nice weather to be outside working on it.

I don't mind having a nice BMW parking next to me now. Door ding odds are greatly diminished. I think that spot is a condo owned by Regions Hospital. Apparently not an intern this time.

FattyBoomBatty · 05-28-2011

It's a 3 series, so your chances of getting a door ding probably went up.

**mlomker** · 05-28-2011

Photos don't really do justice for how tiny the filter inside of the return is. It was obstructed with very fine particles...looks like rubber and metallic bits.

**scheides** · 05-28-2011

Ooh, so maybe just cleaning it out will do the trick eh? Or are you drilling it out too?

I'll try it cleaned out first. I had a 255 in my stock hanger when I was STS so it really should work.

**mlomker** · 05-28-2011

Drill baby, drill.

Huge improvement but fuel pressure at the engine is elevated by 10psi and at the surge tank by 25psi.

I need to figure out how to remove the return assembly from the hanger. I don't see what's holding it in.

**mlomker** · 05-28-2011

Interesting and directly applicable to me. Would have been nicer if they simply told you how to fix it, eh?
