Boost a pump instructions off?

[fumanchu182]

I'm in the process of installing a BAP and noticed on page 117 it says to remove fuse 21... fuse 21 on my PDC is a SPARE. Looking at the list the Fuel Pump is 26 and is a 30A. Should this be the one I pull and replace with a 40A?

So the circle jerk begins... Call HHP, tech is gone... Call Kenne Belle, tech is gone... hey call Barth though as they buy a lot of our products. Call Barth, unavailable... gonna have to figure this out. Might rewire the PDC... I've had dumber ideas.

I can’t tell from the pic, but are you in the trunk fuse block or the under hood one? You need to be in the trunk.
What year car?

Edit - looks like the trunk box from what I can recall. Also, looking online it appears that 21 or 26 can be for fuel pump.

I am in the PDC in the trunk. Car is a 2015 Hellcat Challenger.

So check out this picture.
LX = older Challenger.
LD = Charger
LA = newer Challenger.
I imagine your instructions are either “universal” and therefore universally wrong, or they’re for a different car - the Charger.
I’m sure someone will have info for you in the morning, but if you’re trying to get it done tonight, I’d bet on 26.

Attached another pic, this is the fuse block in my old 2016 Charger. Compare it to yours and see if thats the case (See if they’re different). Sorry it’s a crappy pic, I snagged it from my trailer hitch video, lol.

Thank you for the information, yeah fuse 26 is probably it but it's a low profile bussmann style like this:


They sent a maxi style fuse like this:


I'm gonna reach out to HHP and see what they recommend. I'm not blowing my fuel pump up, that's for sure!

See my edit above ^^^

 

[fumanchu182]

instructions are for the hellcat (chally?)

fuse box looks similar, but 21 is a spare for me

 

[fumanchu182]

Juat noticed the instructions are for a whole KB s/c kit... whack. Will reach out to HHP. Its getting late. Thank you for your help @Jack_Toepfer much appreciated!

The thread fitting for the Boost Reference Adapter is 1/8th NPT 27. I got mine from NAPA: https://www.napaonline.com/en/p/NTH90544?partTypeName=Hose+Barb+Fitting&keywordInput=1/4+hose+barb. Still running a 30AMP fuse but I did a log today. BAP is in and working as expected.



Lots of PSI under boost!

Be careful relying on a BAP. Seen some issues over the years there. You can raise fuel pressure a decent amount in the stock tune as well although there's some debate on whether that's a good thing or not relevant to fuel flow volume.

Thanks for the heads up. 👍 I found the fuel pressure setting in VCM Editor but didnt want to change it as it might be doing the same thing but constant increase in pressure. Since I couldnt find the exact details about the fuel system I decided I would take a chance with the BAP and have it trigger after 5 PSI of boost. I have a all of Thursday at MIR to test it. If I dont like it, off it comes and in the FS section it goes. 😆

Fuel pressure map is in kPa so convert to psi and realize there's a limit as the passenger side has a bypass valve. Some poking around on HPT forum will give you some good info I think even if just for reference. Its pressure by rpm and aircharge if memory serves so you can leave it stock in lower areas and only raise it at max rpm and aircharge.

Did you ever find out what to do for this?

No. The pump was not made with year 2015 in mind. Wound up buying the right fuse for amps but after failure yanked it out and went with doubles.

 

[Hellcattoni93]

The double fixed the fuse problem?

i removed the boost a pump and went with dual pumps, sorry for not clarifying

 

[Hellcattoni93]

Got it
How long did the boost a pump last before failure for you?

Not long, I'd say maybe four track outings and then that was it, my tuner was showing me where it would drop fuel pressure cause it couldn't keep up. It was the Kenne Belle BAP. IMO a bandaid. Get duals. Since you have a 2015 like me, it will definitely throw a code at the top end because you will be over volting the pump long enough that a CEL will pop and the pump will stop and drop and then you'll see it go south from there.
