High Volume Fuel Pump

I think fatchance has gotten two directly from walbro. However, I could be mistaken.

Could be? I just know I would only buy direct from them(walbro). Or another brand by fords4life mentioned. Deatschwerks . Pretty reputable company. I run a inline fuel filter from them on another sled. I have no experience with the pumps they sell but its a sold choice IMO.

My bad grabbed the wrong box, that pump # was for my 07 mustang gt, this Deatschwerks # is what i used with 300hp header tune #9-201-1000

I just ordered one, as they offer a 3 year no fault warranty. Thanks for the info!!

It's a foregone conclusion that if we ask someone who sells larger pumps IF the stock pump can handle 300HP they'd all say 'no.' That said, I've been told the stock pump becomes marginal starting at about 280HP level. Certainly should not be used higher than that.
I purchased the PEFI fuel pump upgrade kit years about 4 years ago. I think he uses a 255 lph pump. When I did the calculations using stock fuel injectors at full flow, even that 255 lph pump can pump way more fuel than the injectors can flow, which means there is still a huge return to the basket keeping it full and overflowing all the time.
Some of us have added an in-line 10 micron fuel filter to our systems making certain nothing can clog up the pump or the suction socks, etc.
I've also had my injectors ultrasonically cleaned and flowed to make sure they're at 100%.
So far, no issues with my PEFI pump and fuel filter. Also, good idea to run the pump directly off battery using the Boost Kinetics relay accessory.
PEFI also has larger tank suction screens if you want. Don't know whose pump they use. Kit is expensive but it's a really nice quality kit.
BTW- no, I don't work for PEFI but their hardware is the best around IMHO.
But if the pump won't keep running right, no one's pump is any good. JM2C

Walbro gss342 pump same as what TD sells but guaranteed pefi is sourcing genuine pumps. Really nice setup and nice electrical connector at the pump. I have not had any issues with their setup either.
