Just installed a DeatschWerks fuel pump in my evo 8. I had a Walboro 255 previously installed.

The new pump plugged in fine, and all of the hoses are on tight, yet no fuel is coming through. I know that the lines are exhausted from the pump being changed, but i've tried cranking it many times.

Any advice would be appreciated.

I thought I read somewhere that the positives and negatives are switched from the Walbros. Might want to look into it.

I know they are on the aeromotives. If they are, I guess I'd have to switch the cord, which I dont have

Maybe that was what I read. Sorry if I misinformed you.

is the pump powering on and your still not getting fuel? or pump isnt coming on at all?

Contact MAP for help, let the key sit on the on position for awhile then try. But I would still cal MAP.

Polarity is the same for the DW301 and the OE pump.

You should be able to contact MAP or get in touch with me via PMs.

I installed one in my Miata, and I noticed the electrical connector was a little tight. Might make sure the plug is pushed all the way down to where it clicks in place.

PM'ed DW; as for the pump, I'm not sure how to tell if the pump is on or not. Advice on how I would know that.

You should be able to hear it kick on and pressurize the system, then kick off, if you leave the access panel and back seat off...

take the pump out and power it with a battery. See if it comes on. If it does then hook a light bulb to the connector and turn the key on, see if the light comes on. no spin, bad pump. no light, no power.

alright, so i can power it from my car batter, and what do I plug up to make this happen?

Tested both stock and walboro pump. They work. This pump is defected.

DW has gotten in contact with me, good customer service and they are sending me shipping info asap.

So far, so good with this company customer service.
