No worries.

Yea 1g has a ton more room to work with, you could fit them both.

If you do go with a BAP, make sure you get the dual version. Per KB's site, only the single version is adjustable, the dual version is fixed at max voltage when triggered.

Stole this from tuners but sounds like he likes it. He's got a 1G and is buddy's with ostar.

I replaced the hanger in the drivers side of the tank that holds the other fuel level sensor with an additional fuel pump hanger so there is a pump in each side of the "saddle" style tank. From there, I simply did each hanger like you would a single pump.....welded -6 bungs in each hanger so I have two -6 feed lines that Y to a -8 up to the inline -8 filter, rail, afpr, and a -6 return that Y's back to each hanger so each side is fed and returned equally. Also, this eliminates the silly factory siphon system. Both pumps are hardwired individuallly with relays. Aside from welding the feed and return bungs to the fuel hangers, this is pretty much a straight drop in solution. Honestly you could do this with even the FACTORY connections with some simple adapter fittings and Y's. Why nobody else has done this yet is completely beyond me. It was super easy and really is almost an OEM feel.

Not sure I'm completely following what he did. Its late lol. Here's a pic of my hanger. So if I don't do the bap dual 450s or maybe even cut the difference between the 450s and 310s and do the walbro 400 since it's quite a bit cheaper than the 450. Idk lol

I guess one of the main reasons I was considering the bap over different pumps was last time the car was on the dyno I was having a big voltage drop that was causing a large drop in fuel pressure. what should be mainly do to a dying alternator. Shane gave me a list of things to do to help prevent voltage drop to the pumps. Which I should have taken care of that list. I guess the idea of the bap was for a little added security in preventing any type of voltage drop to the pumps

If you ask me the major issue you will have in your setup is the turbo.

Its well known in DSM land that a 4294 will be good for around 40psi, anything over that and its a dead end.

This is where the 4202 shines, before ~38psi they are about the same. But the 4202 will keep making power above the 40+psi mark.

I would monitor fuel pressure and see how bad its dropping as you up the boost. Then if you need more fuel pressure a pair of Walbro 400lph pumps would be my choice over a BAP.

Okay this is more really good info. If I can swing it I was thinking about going to one of fp's HTA4294 or hta4205 is what they call it. Otherwise I have a decent deal lined up on a 4202
