Long story short, my " boost-a-pump" module mounted on the frame rail is oozing black nastiness, and smells really bad. Where can I find a replacement? My ex is dead till I find a replacement...

Good news is while crawling around under the Ex, I read the ford tag on the front axle that read "4.30"!
Hopefully the fuel pump is not bad too...

Garry,

If it is in fact a Kennebell...

Boost-A-Pump

They are commonly used across many applications. I have a boost a pump in my Marauder.

I've never heard of them melting down. Do you have install instructions for your Whipple? In theory if you absolutely had to you should be able to reverse the install and remove the boost a pump (return the wiring to stock configuration) and the truck will run. However stay out of boost as much as possible.

What the boost a pump does is overdrive your electric fuel pump(s) to provide increased pressure/fuel flow. If you stay out of boost or very low boost you should be ok to move the truck around.

This is one reason I've always disliked the Boost-A-Pump method for providing fuel. To me, over-clocking the fuel pump isn't the right way to provide the correct, safe amount of fuel the power adder demands.

It doesn't say "boost-a-pump"but it is a black bad tha does that. I read the install instructions, and I hope to try the reverse install to see if it will run enough to drive the mile home. Last night it was too dark and cold...
Thanks for the help. I hope that my fuel pump isn't bad too...
I have sent a email to Whipple to see what the recommend.

Thanks again!

Well... between us girls (No offense Sammie)

Before I'd stand out along side the road and do wiring modifications, I'd fire up my "other" X (in your case, Jeep or Explorer in my case) and drag the offending X back to the house.

And that would be the same thing I'd do in 70^ weather in Arizona...
Never mind whatever temps you guys have in Alaska.

So in the case of my 2004 Cobra when I pullied it for more boost the tuner could bump the fuel pump controller a certain amount through the ECM but any needed increase beyond that required a boost a pump. Again, in this case I didn't require one.

In my Marauder I am not sure if it is returnless ( I suspect it is ) I did get a boost a pump as part of the kit. I had problems during the install with the boost a pump and was advised I could run the car as long as I wasn't doing Banzai runs until the vendor and I could sort out the problem.

I suppose the answer to the problem could be putting a larger pump(s) in the tank but that can be a lot of trouble as well because larger pumps (04 Cobra) draw more current through the fuel pump controller and burns them out, so you have to get a modified one etc etc.

That's exactly what I did with my Lightning. I swapped out the twin pumps for higher rated pumps and put in bigger injectors.

I didn't know that was a problem with the Mustangs.

BTW, I always wanted a SC'd Marauder!

Well KUDOS to Whipple! Called the place in Fresno, Jeff, the electrical tech sends me all the wiring diagrams for the Boost-a-pump module, tells me which plugs to unplug, and then which two to reconnect to put the fuel pump back in factory mode. Hit the key, and the Ex roars to life, He said to keep my foot out of it till I get the new module, but that the module doesn't really come into [play till about 2 lbs of boost. So I drove it home, no other issues, and have ordered up the module, which will be a direct plug and play operation.

I don't think I have ever had such quick and professional tech support!

I am so glad I found one with the Whipple!

Well I think that is sort of a broad statement.

My Marauder has been S/C'd now for nearly 30k miles and I've had no S/C related issues.

If the kit is well designed and the platform is suitable then S/C isn't the anti-christ.

Did you have to modify the FPDM ( I believe that is what is called)?

My logical pump upgrade for the Cobra is the twin GT pumps but they like a modified FPDM. My tuner said I am fine with the Cobra pumps. I am not even near to pushing their limits at the moment. Same with the injectors. I am, OTOH right at the edge of my MAF range so I will be installing a BA2600 MAF after the holidays and retuning.

Dunno what that is, but no, no modification was needed to run bigger pumps and injectors.

For the others in the Supercharger community, I have a question. I did the premium fuel for the first few tanks. Then I did a tank with 87 octane with the appropriate amount of octane boost, and I ended up with detonation on high boost conditions. I do not have gauges yet, but as soon as I put the premium (90 octane) the detonation went away. Do any of you use octane boost?

Also what brand gauges are you guys using for boost, fuel pressure etc?

Thanks!

I've never bothered with octane boost. The cars were tuned to run on 91.

Detonation will kill a boosted motor QUICKLY!

Yes I agree. Unfortunately I live on an island, and can only purchase 90 octane, as that is all that we have, unless I was to try to buy Av Gas that is sold for the small aircraft on the island...

Do have factory gauges, or aftermarket?

Thanks again!
