Default WARNING. If you have installed an aftermarket fuel pump PLEASE READ.

I just had a VERY scary experience installing my PE fuel pump.

I felt I needed to post this right away. If you have an aftermarket fuel pump on your WRX you must Check the size of the lugs on the connection of the pump. Even though the connector might look the same from the outside the lugs or connection point might be different.

On the PE pump the connector is identical except for the fact that the stock lugs are 1/4 inch in size and the PE pump has 1/8th lugs. This caused a loose fit and ARCING! The pump and connector are INSIDE the fuel tank.

Serious injury or even death may result if the fuel is ignited. Especialy if the tank is near empty.

PLEASE CHECK YOUR AFTERMARKET PUMP!

Solder the wires directly to the pump terminals... you won't have to worry about arcing . How often are you going to need to change a fuel pump ?

You missed the point. The PE pump is a direct replacement pump. There are no terminals to get to. You cant solder to this pumps connector. The connector is vulcanized into the housing and there is a plastic guard over those parts.

That sounds eerily similar to what is suspected to have brought down TWA flight 800.

xphilxcorex,

Tell me more of this Walbro pump. Is it the same Walbro pump available from several Subaru vendors? What is the Summit part number and such? $115 is a good price.

I'm looking for a pump that fits PERFECTLY.

Default hmmmmm

this pump is a perfect clip in replacement. no modifications neccessary.

part number

bbk1607. that is a summit racing part number.

it keeps pressure the same as stock but flows much more.
it is a 255lph pump.

not sure if it is same part as what the other scoobie guys are running... but you could easily find out if it is by calling whoever it is and giving that part number.

hope this helps... if not just ask more questions...

thanxxx

Got my Walbo replacement TT pump here, part # GSS341:

http://www.autoperformanceengineering.com/

Same thing, fit without problems, and was about $115 shipped from TX to VA. Another option, especially if you're close to TX.

Reggie, I don't see that part number listed on his site.

Can you double check?

Thanks!

If you have a turbo upgrade eg PE1820f and 15psi
550 or 620cc injectors, what size pump would we need anyway?
255 or higher?

Regarding the sparking issue.. It's a good point, however very easy to fix. I installed my PE pump today, and yep - sure nuff the connector was loose enough that it could have sparked. However, simply inserting a sharp object under the connector to bend it helped to make a very tight connection. (makes more sense if you see it).

Default Part # for Walbro Pump

Dan,

Took that off the box the pump came in. Someone else told me the same thing, but APE sells two TT replacement pumps. Best to call them, because one supports higher pressure than the other.

WAL255HPM shows to be a GSS340, not a GSS341 at www.jdsperformance.com.

I know this is a little off topic, but I have noticed that in some cases you can use domestic pasrts that are easy to find a not to pricey. Has anyone looked into other injectors.. ie SVO or the like.

I don't know the price of high capacity WRX injectors but mustang injectors aren't very expensive. You can get 8 30#ers for $200, or 42#ers for like 450ish.

I knoe 42#ers would be large enough, since they will support a blown 5.0 making over 500fwhp
