2018 mustang gt 22k miles
Whipple 3.0 gen 5 stg 2 11,500 miles
First time poster, long time reader.
I've sent a datalog to Whipple and he reports there's definitely a mechanical problem with my car. Fuel level pressure is 40s and desired is 65+. So after reading another similar thread, the dw400 was the culprit and that's what I have. So I get the new pump that has the check valve built in and go to install it. On the fuel assembly, when I was taking off the hose that connects to the bucket, I broke it. After trying to work around it to no success I went ahead and purchased the whole assembly from the dealership. So now, I'm thinking since the top portion where the fuel pump resides isn't broken, why not just put that part of the assembly, and insert it in the new bottom portion or bucket I think is what I read it's called. By doing this I save time by not having to cut new hat to fit dw400 because the original was already cut and now being reused. So I get it all back together, using new hoses that came with the pump.
After initial priming and with the nguage displaying flp psi, when I first cranked it up it still took a bit longer to start but when it did I noticed the gauge was reading upper 50s to lower 60s. Perhaps even higher but the numbers were fluctuating so fast I can't be exact on those numbers. But after less than a minute the numbers were back down to 40 psi and upper 30s. The p008a comes back on after each restart even if I clear the code. Should I pull the assembly and put the new pump in with the new top hat that I elected not to use? Would traditional hose clamps be enough to keep the hoses in place since I cannot reuse the permanent clamps? Tia
