Focus SVT Pump

I am in the process of getting my car supercharged and dyno tuned. The orginal AEM 320 pump I have, I deleted the fuel pressure relief valve and the line from the pump to the hat busted open. My tuner is now suggesting I go with a SVT focus pump ,as the AEM is also going to be harder to tune. One problem is that I discarded the fuel pressure valve and would need this going with a focus pump.

My question is where can I find a SVT focus pump with a pressure valve(or complete hat) that will be able to drop in for a decent price?

I don't know why the AEM pump would be harder to tune, but my tuner didn't have any problems tuning mine.

Did you delete the excess pressure valve?

Are you talking about the PPRV valve?

You definitely don't need or want one of those to run the SVT pump.

Lots of the Walbro pumps have an internal pressure relief valve but I don't know if the SVT pump has one but you really don't need one but you need to use a good quality submersible fuel hose to connect it, it definitely needs to be the submersible type, if it doesn't give you sticker shock when you get it, it not the right stuff.

I guess your tuner is pretty familiar with the SVT pump and that's why he wants you to use that one.

Unfortunately there are better pumps out there for the money these days than that pump, especially since the price on the SVT pumps has gone up a fair amount.

I'd ask him if he is familiar with Walbros latest improved version of the Ford Supercar GT pump, its a much better pump than the SVT one and if you shop around you can get them for around $100.

Here's the pump I'm talking about:

Walbro F10000302 (Improved GT Supercar) Fuel Pump

These can be put in a stock GT basket but from what I understand you will need to do some cutting on the basket.

This version of the pump does have an internal relief valve, I think its set at 85 psi.

My AEM is the same concept as the Walbro, drop in , shave the basket and splice some wires. I am on a budget , but am willing to pay a little extra to do this once and be set. The kind of pump I am now looking for is more of a drop in with the PPRV, and I may need to buy the entire basket/ hat since I already spliced the wires. Just looking for a place to get the best price.

I am referring to the PPRV in the posts above by the way.

OneNice, do you mean you had that many failures of that pump?

How were they being used and how did they fail?

We're they the original GT pump or the improved 302 one?

No, I just dropped the AEM pump in the stock bucket and drilled a few holes to let fuel in faster.

My division x sure doesn't have a internal pressure relief valve. I believe I've read the division x 340 is the same as the kurgan 340 and maybe walbro. I might possibly be wrong. I don't understand the big deal in tuning the fuel pump. If I can do it then I'm sure someone who does it for a living can. Definitely go for something better, not that the svt pump is a bad pump because its a good pump but there's better out there. I'm happy with the divison x, although I think it maxed out pretty quick on my setup.

Also if you do the pprv delete you need some gates submersible fuel line. It comes in 1' sections and it's around $30. Do not run regular old fuel lines. The fuel will degrade it and it can result in a catastrophic failure.

I agree, unless there is something basically wrong with your current fuel pump and system he should be able to tune with it.

But if there is something wrong its likely not the pump and more likely some problem with the pump fuel hose connections or the pump electrical connections.

Just swapping the pump itself probably won't fix those issues.

Did the tuner say specifically what problems he was having with the current pump?

+1 my tuner had no issues with my AEM 320 with PPRV. Trust me, you will not want that PPRV. I've regretted leaving mine on there since day one. 2-3 shift has a loss of fuel pressure since there is a spike of pressure during shift. Thinking about dropping the tank again just to remove that stupid little piece.

I've tuned all of those pumps with ease. You never run a pprv with any performance pump they work better without. You need to find a new tuner because whoever you're using lacks experience and technical ability. Think about what I'm telling8 you... multiple people on here have custom tunes working well with the pump your tuner can't seem to tune. I've tuned all of them and can do do in about 20 minutes.. time for you to find another tuner or I fear your next post will be related to engine failure

Hey guys thanks for the big response. I just went with a Walbro 255 drop in to make things easier and get my car done. I will be selling my AEM 320 pump(E85 compatible version) which works, but as you can see I am going a different route.
