Walbro and MSD are good choice for the cost. If you plan on going higher than 350+hp anytime soon then look into upgrading different fuel pump, although Flex fuel pump itself are very good and can handle over 450+ hp

They do work with flex, but you want to look at fuel pump with e85 capability, some aren't, some are meant for diesel, etc.

i wont be using ethanol considering the nearest place that has it is like 2 hours away. just wasnt too sure about what the others were sayin in this thread about it not being adequate enough for the 2.2flex.

thanks what... i guess ill just go with the msd one used in this how to being as its cost isnt bad at all

Cut the wire that goes into ac delco pump and connect to the inline fuel pump, voila, you have one inside the fuel pump assembly without install externally.

Of course, if you plan on going extremely fast, this pump isn't such a bad idea lol

Next to stock ac delco and A1000

If i install theA1000 do i need to do anything under the hood? or just mod the gas tank to run this outer pump?

Nothing under the hood at all. Just make sure you remove the stock pump from the sending unit or the A1000 will have to do the work of sucking the fuel through the old pump by turning it.

I just disassembled my stock assembly. If you want to retain your fuel gauge, you do need to slide that whole assembly that has the three springs back into the housing where that sock filter is right? So when I run the fuel line inside the tank it doesn't go to the bottom of the assembly like the brown one did, but outside of the assembly to the bottom of the tank? Meaning there is no use for that sock filter on the bottom of the assembly now? I'm just getting a little confused here...any answers would be great. What do you do with that little black hose that ran down to the sock filter? Just leave that stuff open? It went from the pump motor to that filter. I wish I could take pictures but those of you who have done it should know what I'm talking about.

I just did this to my 1996 S-10 LS. I used the original grey wire from the old pump by just cutting it at the plug and pulling it to the new location on the frame rail. No splices PLUS it keeps the wire in the loom.

I removed the old pump. I left the little black hose just hanging. I installed a fuel line from the top of the pump to the old fuel strainer inside the assembly. I did not want to bypass the in-tank filters. I cut the grey wire from the 4 prong plug and pulled it down to the area where the fuel filter is. I cut out about 12" of the fuel line. I clamped a 2" piece of hose to the old line and to the new pump. I clamped a 2" piece of hose from the pump to the filter and then a 2" piece from the filter to the fuel line. I can send pictures if you like. E-mail me a edsgarage1-at-yahoo-dot-com.

I bypassed the sock filters and I probably shouldn't have, my line just runs to the bottom of the tank. I cut the gray wire at the plug as well, but I mounted my pump to the gas tank cross member. So I extended it the + about a foot and a half, and then I have fuel line running just up to there, and then back down to where I cut the steel line off about an inch and a half away from the fuel filter. Ground is bolted to where the ground for I think it's the filler neck is. I cut that little black hose out of the assembly though. How hard was it for you to push the stock assembly down far enough to seal that blue o-ring to get the snap ring back on the top of the assembly to secure it? It was a PITA for me........

[702s10]

For anyone doing this, make sure for the inlet hose INSIDE of the tank you get submersible hose. It is pricey but you will need it. Also, plan on purchasing a new o-ring that seals the sending unit to the tank. I had problems with getting my stock one to seal because it expanded once removed. It was about $10 from the dealership.

It should be noted that you will need to use submersible fuel hose in the tank. I did mine with regular FI hose and had to redo it 2 weeks later. The hose I used was "Gates" part # 27097 which is NAPA # H213 3/8" about a foot long.
Cost me $19.00 from NAPA. My old hose was soft. Don't forget the FI hose clamps. Regular hose clamps will chew up the hose.
