    Terry, what option do you recommend?

    and could you list where to acquire the parts? *cough cough add to your website*

    Yes, and how you determine things like that is through testing. Start at the pumps and move forward. Ripping lines out when they haven't deemed to be restrictive is the cart before the horse when we haven't found the limits of the HPFP or really limits of the E85 and stock pump in parallel yet. Since I am in there and already have the E85 mounted in the bucket I may just run down the street grab another E85 and run it in parallel with the first. Haven't decided yet

    He alread did the parts list. To run parallel, just buy extra Tee's and use as needed. Series just buy extra 5/16"s connectors and use as needed. I mean you guys are smart enough to figure that out.

    No issue copying the results over here. On the factory + E85 parallel, I have not tested it in car yet so I'm not sure if the regulator is up to it. Also not sure if the power supply is up to providing that sort of current.

    Its not in this post. Check the original fuel pump post. People list all the parts and part numbers to get you going

    Terry do know off hand, what amp fuse the fuel pump circuit is using? I am going to just assume the amperage is not an issue since the Vishu upgrade is pulling the same amperage and no one has posted anything about issues with blown fuses etc. Guess I'll be the tester for the parallel set up. Only problem is. Car isnt running, so I can't just install and see how its working.

    Probably a safe assumption. I don't know the fuse number off hand but its on the little fuse card.

    Good results. Now how about running set restriction and varying pump output to 75psi and then reading the current. The objective when installed is not really to run the pumps at max flow IMO.

    Great job Terry! I'm very eager to see what sorts of results we'll see. I know that the vishnu system offers some kind of machined Venturi connector to the Walbro in-line pump. Is such a setup done here? I don't know whether it makes a difference or not. I am speaking from ignorance.
    The pump they are using is the same pump we are using, and its meant to be used as an in tank pump. Since they are running it in series they've had to machine an adapter to hold the pump and force pressure in what would normally be the pumps filtered input. So to simulate that I just hose clamped a line on the input. It's not very elegant but was not leaking and thus good enough for bench testing.

    At the end of the day they are charging $600 for a $200 pump kit and have a lot of interest to keep that gravy train going. So no matter what we say or how we test it I'm sure Shiv will come up with some great reasons why our tests are not valid. But I've gotten everything I wanted to know from the testing.

    All things considered I like the single Walbro w/ OEM venturi because I know it works well, and clearly flows more than enough for my needs. But I'd love to see a customer test the simpler Walbro $100 inline option.

    I didn't so much as hint at ripping lines out. I said it should be determined if they are a restriction. That can be done either through testing, or by measuring the ID of the line...

    Would running the lpfp system at 90 or 100 psi help the hpfp to keep up at really high fueling targets? If the hpfp can't be replaced yet because there are no aftermarket parts, what can be done, anything?

    I was originally thinking about getting the in-line system, then, after reading the speculation, decided that a single Walbro E85 would be best. However, you recommend using an in-line universal instead of an outright replacement for people running in the mid 400whp range. Is this because of the difference in price?

    The current the in-line Walbro E85 (Vishnu) demands kind of scares me. I wouldn't want the extra heat wearing things down more.

    Price and ease of install for those who will never make more than 500whp. I can't say I suggest it yet, but I'd like to see some guys test it out, as it seems promising on the bench.

    Ok so got the parallel rig put together and installed. Its honestly pretty straight forward. You have to leave out the stock pump holder, and rotate the stock pump slightly so the venturi nozzle is not in its holder just slightly off to the side. This will allow the Walbro to share the bucket with it, while the venturi still pulls from its original location. Once you do that the Walbro with its sock will fit into the bucket with the stock pump and they actually stay in place very well. Once you get the bucket lid back in place you will see if will not fit now, but all you have to is cut out a small section and it clears both pumps great. If you secure the bucket top with a couple wire ties you are good to go. I just powered both pumps in tandem off the stock plug, if this is an issue and it pops fuses we will have to address it then. Once you get to the lines its just 5/16" fuel line coming off both pump out lets fed around the collapsible leg and coming into a 5/16" Tee. Secure it all with clamps and this will be going to the orange line. I put some extra hose on the orange line to give it a little freedom to move in the tank so not to pinch anything. It all fits back in pretty nice and seems like it should work well. Took a few pics. But not too many. Now we at least hopefully wont have to worry about low fuel pressure once we get stage 3 installed. Cheers

    Awesome Tony! I know you had an HPFP off, does the 5/16" line carry all the way to the HPFP?

    Honestly I am not sure. Terry would know better than me. My Long block came with the HPFP on it. I just pulled it off, never followed the line all the way forward. I will take a look sometime this weekend

    Well if it is 5/16" all the way up to the low pressure sensor, assuming 15 feet of line, it should do about 600-650lph. The current will be pretty dang high though, like 40A? I would take a quick peak in the glove box to check the fuse rating (assuming the fuse is in the glove, not sure it is). Usually the wires are sized sufficiently, but just check to make sure they got a #10 in there. From the pics it looks closer to #12-14 just guessing.

I would take a quick peak in the glove box to check the fuse rating (assuming the fuse is in the glove, not sure it is). Usually the wires are sized sufficiently, but just check to make sure they got a #10 in there. From the pics it looks closer to #12-14 just guessing.

    Terry said its pull about 20-21 amps with both pumps. That is high, but no one has had an issue with the vishnu set up. So lets hope this is the same

    With two E85 pumps? or the stock pump and the E85 pump? The spec sheet says 19 amps at 72psi, but I suspect that is with factor of safety, so probably closer to 14-15 amps.
