Just installed mine today in prep for a tune this week. DEAD SILENT... thought we messed up the install. Turned the key to the on position and nothing, not a peep. This was with the access cover open and having an ear within inches. Cranked it over a few times and it fired right up.

Install was pretty straight forward. Has reverse polarity from the 255 it replaced and the included sock filter needed to be shave to fit properly. Other than that a straight replacement for a 255.

car went in yesterday for the tune. Pump ran out about the same level as a 255. Kind of disappointing.

Bummer for you, but good to know.

Do you have a fuel pressure gauge in place? Are you watching fuel pressure drop on it while you're in boost?

According to their site:

"This pump outflows the Bosch Motorsports 044 and draws less current due to better engineering, materials, and machining tolerances!!"

I'd be interesting to see what type of voltage you are giving the pump?

Here might be another option???? (not sure of if it could be a drop in replacement)

Zivman, we received your old Walbro pump and flow tested it against our Pro Series PT342 pump serial# 00104. Please see the results below.



This is why I am unsure of the results you had on the dyno. I have shipped out the replacement PT342 pump serial# 00104 with it's flow chart to you yesterday, along with your Walbro back and the wiring kit we discussed. Please let me know the results you have with this and rewiring kit.

Thanks,
Jay

Hi, this is not a problem. The typical amp draw is about 3-4 amps over the Walbro. The bigger problem is the voltage drop along the long small gauge wiring. Any current overdraw issues would cause a blown fuse long before other problems.

Yes- you are right evolancer04. I did not notice it over in that section- I usually just pop in for a quick look here in the Alternative Fuel section. Looks like it has been a good thread so far. Thanks for pointing it out to me.

after some discussion I don't think one should count out the jayracing pump. it definitely outflows my 255 that I pulled _> I have the flow charts to prove it.... problem lies in the stock wiring. it can't pull enough power. I will be rewiring the PT342 and be going back to the tuner.


I would think the DW pump would fall to a similar fate

Hey, it looks like this rewire should help out. We just had a customer put down 621 AWHP on a Mustang dyno with E85 using our Jay Racing Pro Series PT341 (DSM Fitment)
