I just finnished an a/a intercooler on DHG 00293, today it put down 402rwhp/371rwtq......However, i'm running out of fuel between 5000/5500 rpms. I've currently got the single focus pump that came with the vortech kit.

My tuner suggested I get a KB boost-a-pump, but I was just wondering if theres a cheaper alternative, because i'm not looking to push my current set-up too much farther. I've found focus pumps for $110, would it be possible to just add another pump without major modification? or is there any other route I could go?? Any help would be much appreciated!!

At your power level, an '03 cobra tank and dual pumps would probably be the best solution. I don't know that cheap should be the goal on building a fuel system, as adequate fuel is cheap insurance that your motor will not detonate. Those are just my thoughts.

If your tuner suggested a boost-a-pump and you trust him, then that is probably a cheaper route.

I dont mean I want to go cheap on it, I never go cheap on anyhting, I just meant i'd rather not dump a ton of money into building a fuel system that isnt going to need to handle too much more power than it already is. I had thought about the termi tank and pumps, usually go for $400+.

When it comes to Fuel systems and oil systems, going to slightly more expensive route is the best bet sometimes. Go with either the Boost-A-Pump or the 03/04 cobra tank with dual pumps, or what i REALLY recomend is both.

I suggest getting a pump from a Lincoln Navigator. They fit into your tank and supply more fuel than the focus pump. This is what my tuner said to me anyways. Something to look into.

My friends 03 KB cobra is at 550rwhp with the stock pump and a BAP, so I think the BAP will be fine for my set-up because like I said, i'm not looking to push this current set-up toomuch farther.

The Navi pump idea is interesting, i'll look into it, but I might of already found a BAP anyway.

With the KB you use a BAP with the stock pump so it should work fine with your upgraded pump.

Glad to hear it. Sounds like you have it under control with the BAP.

how do you like the SLP setup - im thinking of going with the LT and catted x cross
I love the SLP, most people dont like it because it is obnoxiously loud, but I love it.

One word of advice, unless you plan on having your engine out of the car anytime soon, dont bother with the Lt's.

There a real pita and you'll most likely end up paying more to install them than the parts actually cost....and they dont make it toomuch louder either

Linear lean-out at the end. The in-tank pump provides volume and pressure of fuel. Is your pressure falling or is the volume insufficient (different problems that cause the same effect)? Boost-a-pump should help but a proper main pump will ensure you get all the fuel you need. Seriously, a 03/04 Cobra tank and pump is a direct swap and is a hell of a lot cheaper than a burnt piston...

Just my $0.02

Has anyone had any experience using the GT pump? I have been doing a lot of research and talking with different shops, and the GT pump would be a direct plug and play in the existing tank. It is supposed to handle up to 550rwhp. I think it sounds like an easier alternative to the cobra tank and dual pumps, and should be better than the focus pump.

I run the SVT Focus fuel pump which comes with Modular Powerhouse's Mongoose kit. I'm currently at 370 rwhp - a lot of guys are running in excess of 400 rwhp with that pump. Check out their forums. Pump drops staright in the existing basket. I guess it depends if you are planning to go for more hp whether or not you go for the BAP or twin cobra pumps.

Im running the same pump and my numbers are in my sig. My tuner says I still have alot more to give but the too high intake temps can cause det.
