Look familiar?



I found the quick connect fittings for the top of the stock pump/fuel filter...



..looking for a place to order them but they come with your favorite kind of clips (see previous pic)

Nice job on the DIY...good times!

Looks good thanks for the write up. One thing I would be careful of is the heat shrink in gas. I am pretty sure it will dissolve.

You know, I didn't really think about that one. I'm going to check on everything in a few days to see how it's holding up. Hopefully the heat shrink is more like plastic than rubber.

Depends on the kind of heatshrink...by the cheap stuff such as polyvinyl....yes. Fluoropolymer....not so much

Took a look at things over the weekend. All rubber hoses and heat shrink look fine!

Writeup looks good. I think this is probably the best option for most customers needing a low pressure pump boost.

I know you mention it in the DIY but to avoid any confusion as it appears in some photos do not use the foam/rubber insulation sleeve on the pump.

Agreed. It will definitely break up very quickly.

What I would do if I wasn't sure if something was going to hold up or not, is to get a gallon or so of E85 and put whatever component you're not sure about in the fuel for a couple hours. I'm sure you can tell pretty quickly if it's going to hold up or not.

Common sense goes a long way!

Thanks for taking the time to do this. You're a damn good technical writer. I'll be installing this soon. Do you recommend your Walbro model 392 pump for my G5 ISO/flash/RB turbos set up? I don't have access to E85. I use 112 leaded fuel at the track. Is their another suggested pump I should use? I particularly like the fact that the OEM pump is not molested and the 2 pumps run is series.

Thanks OB.

I really don't know enough to answer that question. I would defer to Terry or someone else. But yes, I really like the fact that the stock pump is more or less untouched.

If I have the vishnu flex fuel kit, and I want to run 100% e85. Could this pump and DIY work? I rather pay 100 bucks than 600 bucks for the Vishnu lpfp if it does the same thing.

Ha ha. Welcome to BMS.

It actually costs about $140 with the fuel filter and other stuff. But still makes a little more sense than $600.

Sorry I did not know this was a BMS only thread. Im not trying to hate on anyone. Was just trying to figure out which set up I need to go with to run 100% e85? I saw another thread by terry removing the stock lpfp and installing the e85 walbro lpfp. My current mods are ets fmic, injen dci, VRSF ******* dp, VRSF ******* exhaust, BMS oil catch can, procede rev3, and procede flex fuel, aiming for around 500hp. Much appreciated for the help.

BMS only thread? Nah, just mostly bms pro people. Some here only have a bms dci, if that. Just a forum in the end.

I wouldn't say this is the same thing as his option. His is pre assembled :-) lol and he may use other pumps, who knows. What is the same is the effect.... increasing the low pressure fuel system output. Has nothing to do with tune, Cobb guys use this too.

For your goal of 100% e85 and 500hp that may be obtainable, but will stress the turbo's and hpfp, which there are no upgrades for yet. Also, no piggyback (vishnu or jb4) will get you to 100% without a change to the tables in your computer. JB4 users do this with the Cobb AP and free maps from Terry, Vishnu (I believe) offers a flash service, but requires mailing your computer to him. Or does he support cobb stacking yet like the jb4? Anybody know?

Edit- thought this was the pump replacement thread not booster pump (on a phone). Same logic applies, this will help you in your goals, but I don't have a clue if shiv offers a boost a pump solution to compare this to, I'm only aware of the setup he runs on the st cars.

I did send in my dime to get flashed by Vishnu. Sorry forgot to mention that. With the flash and this DIY would I be able to achieve 100% e85? Btw I had the jb4 g5. And I do miss it!

With the flash you can support 100% e85 until you make enough power that you lpfp can't keep up and low pressure crashes. This will raise that up to ~ equal the hpfp in output. The oem walboro replacement may have a minor edge for 500hp though.

In reality, the people who go boost a pump are after install simplicity, as for many this will max the hpfp output. People who replace the oem in the bucket are either trying to get every last bit from the low pressure system, or are just more comfortable with one pump versus two in series. Power wise, you will be limited mostly by hpfp with either option +/- 10-15hp maybe.

Again, no this is not a BMS only thread. My point was that you will find that you can get the same or better outcome in performance, etc., (personal preference, really) by going with BMS vs. Vishnu products. The biggest difference is the cost. If you really want to pay 50% - 300% more, go Vishnu

Personally, I love the steering wheel controls and the fact that Terry is super involved and responsive with his products. I have not found a reason to switch to something else.

To each, their own.

It is my understanding that the testing done by Terry and other members with a 'Boost-A-Pump' is not the same as what is being mentioned here in this DIY or other threads. In 'Setup 2' we are using a 'universal inline pump', made by Walbro in this case. A 'BAP' is made by Kenne Bell and is just an electrical add-on to an existing fuel pump setup: http://www.kennebell.net/KBWebsite/A...boostapump.htm

The reason I'm saying this is because I come from the Mustang world where the Kenne Bell BAP is EXTREMELY popular. Someone correct me if I'm wrong.

I speak of boost-a-pump not as a trademark but more as a "boost" as in an increase in output to a "pump" as in the OEM fuel pump. I apologize if I infringed any trademarks or created confusion, lol. Probably should have said helper pump or inline pump option. Force of habbit.
