Camo, from that pic it is clear you have too many fittings cluttering up your work space ... I can help you out with that.

Alright, has anyone sourced the cheapest place to buy AN fittings?

This OBX valve is going to require a male -6AN to 3/8" barb and a female -6AN to 3/8" barb and I am not seeing any -6An stuff on ebay.

For Camo or anyone else looking to up their AN fitting collection with another 275 pieces .... lot for sale on ebay. http://cgi.ebay.com/ebaymotors/Whole...item19b8507cef

I just recieved the OBX unit today. I can't blow through it at all

Which is strange as pushing the ball in with the tip of a pen is quite easy. Blowing in the reverse direction does not seal air tight. While I am sure the significantly higher pressure of a fuel line would actually help to press the ball into the seal .... I am not impressed. I probably just pissed $30 away.

The aeromotive ones seal air tight blowing in reverse. Sometimes I would have to smack the check against my palm to get it to unseal so I could blow through it again.

I wish they put some kind of flow #s with these things. For $60 I could run 2 of the cheaper units like -- < == > --

Trying to save money has a lot of times ended up costing me 2-3x more than if I bought the bling part to start with.

Yeah, not the first time being cheap has bitten me.

I have emailed the seller (q.sport) a couple times and haven't heard back.

I think I am gonna go with the Earls unit.

So I had my walbro 255 pump fail New Years Day. After a few trips out and say 24hrs max time on the pump. I am running a wix filter regulator like stated by this topic. It has the return coming out of it.
I just wanted to pass this along. I was wondering if the filter was designed to feed fuel back through the return if it becomes clogged. This would keep your pump from dead heading. After speaking with the Wix Engineers I have found out they filter the fuel going to the engine and back to the cell. So if it does get stopped up you will not return fuel back to the cell. I think this is a bad design. But don't know any other filter that operates different. Just a heads up.

What brand is that bottom filter? I guess I need one like that also. Does anyone here know a good way to check the filter regulator to see if it is clogged up?

It's an Earls 100μ pre-filter. As to the plugged filter question, look to a fuel pressure gauge.

Good luck.

I was trying to see if there was a way to check it off the buggy. Cause I am trying to eliminate a bad pump or stopped up filter. I hate to fill the cell with a stopped up filter and a new pump and it was just the filter stopped up. Or the other way around. I am going to check the pressure tomorrow and then try changing the filter first. My Walbro is screaming and I believe it is dead. But I suppose it could be a clogged filter causing this also. Wish there was a better way to do this without starting over buying fuel parts.

I have a new Walbro Pump and Filter should be here tomorrow. Surely the filter didn't clog that fast. Maybe 24 hrs on it and the pump.

Often times a noisy pump is starving for fuel, so I would look for an issue in the pickup.

In my system, the 100μ pre-filter is basically a removable and serviceable screen. With that sitting in front of the pump, it keeps trash out of the pump without being so restrictive as to cause starvation/cavitation. It also helps to keep the post pump filter/regulator clean, as that filter's primary role is to keep the smaller stuff out of the injectors.

Good luck.
