Re: 1986 glhs #163

Ilikeshelby’s,

My plans for the GLHS is to make it reliable. I have no intentions of improving the performance characteristics. Is the model of the walbro called a 255? I was on summits website and all the walbros are 255l units.

I appreciate you leaving your GLHS stock, but I hope you at least have the MP stage II LM in your car. The stock GLHS sloped boost curve LM was terrible! In an attempt to make the tranny survive through warranty, Shelby Automobiles really compromised the driveability on the stock GLHS vehicles. You are leaving vastly improved driveability, economy, performance, on the table by using the stock GLHS LM.
The 255 pump is the output in liters per hour, not the part #. Like Steve said, you really don't need a 255 pump if your GLHS is going to remain stock. Beware there are lots of fake Chinese Walbro pumps in the market. Buy from a reputable supplier. That is another reason why I like the Deatschwerks DW200. That NOS pump assembly mentioned earlier would be good should you be able to get it cheaper than advertised. I believe it had a make offer option. That would just be a plug and play.

Re: 1986 glhs #163

Are they still selling Walbros in Denso boxes on rock auto? Both of the ones that I picked up like that still work great under boost.

Re: 1986 glhs #163

Just my opinion but the 2 pumps seem to out last the single units.

There are many problematic replacement pumps is one concern.

I run a Super 60 pump in one of my cars but it isn't a direct intank fit.

It's been a great pump though for 20 yrs.

I would replace the sock and give your stock setup a try.



Thanks
Randy

Re: 1986 glhs #163

Just a Update,

I finally got all the fuel parts from rockauto. I ordered a new fuel hanger assemble from a 88 or 89 omni, fuel tank and a specra sp1252 fuel pump. I just realized that the fuel pump does not fit in the new fuel hanger assembly. I take that i ordered the wrong pump as the diameters of the fuel pumps are different.

Re: 1986 glhs #163

255 pumps are larger than the 190 and OEM pumps. The turbo Dodge fuel pump installation kit should come with the needed sleeve and other bits and pieces and pigtail...

Re: 1986 glhs #163

Well....if you buy your Walbro from someone like Cindy at FWDPerformance or Chris at turbosunleashed, it comes with it. Otherwise you have to determine what the Walbro installation kit number is and order one from wherever you can find it using Google, Bing searches maybe. I dont want to come off as being flippant here, but they only sell pumps with the needed kit and all the installation goodies as part of their turbo Dodge specific value add.

Off the top of my head, I do not know the installation kit and accessories bag number. A bit of Googling and you can probably find it...or maybe you can contact Chris or Cindy and see if they will/can make one available to you. I did not read your entire thread so I don't know where you sourced your pump or exactly what you have so the suggestion I make might not be appropriate in your case. But I do know if you got a kit from Cindy or Chris, which was probably at least suggested in a previous post, you got one of those kits with the genuine Walbro pump.

I just did a pump replacement and might actually have a spare sleeve but will have to look. Let me know if you might need this and I can snap pic for you to determine if it will help you in your current situation.

Re: 1986 glhs #163

Several of us repeatedly suggested to you to buy a Walbro or a Deatschwerks pump and you buy a Spectra SP1252. Now your asking for help because it don't seem to fit. In the Rock Auto description, it says the SP1252 is for an external mounted pump! Hum, you made not the best choice... But hey it was like half the cost of a Walbro!
If you INSIST on buying fuel pump from Rock Auto, look up your choices for a 87 Charger turbo (internal single pump). It gives you some additional options not listed under an 86 Omni. Also has pictures so you can see exactly what your purchasing.
BTW as previously mentioned, the Walbro 255 and the Deatschwerks DW200 will require small mods to fit too, so if your a plug-n-play only guy, don't buy those either.

Good luck,

Todd

Hi Randy,
I haven't kept real close attention to this or any other threads lately, but it seems obvious that one or both of his original pumps are bad. I've personally seen many internal pumps leak badly or fail completely. They really seem pretty pitiful for a EFI pump IMO. They sort if remind me of windshield washer pumps (lol). It's sole purpose is to prime and feed the external pump. So unless the OP can determine for sure the internal pump is good and not leaking, I wouldn't go that route.
What I HAVE done on a higher HP GLHT a long time ago, was use the TBI internal pump as the internal pump, feeding a Bosch (OEM)external pump. I was worried about the current draw on the factory harness running two 'real" pumps, so I ran separate ground and feed line to the external pump. This worked great and was very high pressure and volume. Plenty of pump for 115+ MPH traps. OP could do this, but it would be real overkill for a bone stock GLHS.
