Swapped my low pressure fuel pump a few weekends ago and keep getting this code:

"193208: Plausibility check failed between consumed & remaining fuel quantity"

Fuel gauge doesn't really read the right amount of gas in the tank, it just stays around 3/4 most of the time. The float isn't stuck because I've taken it out multiple times since then and it works fine, so what else could it be?

I have this as well, every tank it happens once. I thought first it was the Hydramat interfering with the float, I built my own Stage 2 with Walbro 450. I checked it twice and it was not the Hydramat so I thought it was the level sensor so I changed that but it still happens. I thought maybe it was just me. Sorry I can't help but I am subscribing hoping someone can shed some light.

Mine will go down normally until somewhere slightly around half and then suddenly go up to about 3/4 full and then after a while it will go back down when it gets below 1/4.

Ok that makes sense, I built mine also and i didn't know if it was my pump or someone else's. I remember on my N54 it did the same thing too. Thanks for the reply though I'm glad I'm not the only one lol

Yeah glad to hear it's not just me. I still don't understand why it happens though. I may be adding a second Walbro for a stage 3 when I upgrade my turbo, if I do I will eliminate that large Hydramat and put 2 smaller fuel pickups on both pumps, maybe that will fix it.

What are you using for a fuel pickup? Mine is 15"x3"

I'm only using the filter that was included with the Walbro pump. I thought about getting a hydro mat but at the time I just decided to run the regular one and upgrade later.
