You can also run pumps in series like the fords. One pusher pump and the primary pump. It will not increase the flow rate of both pumps but KEEP the same flow rate at higher pressures because the pumps work less to push the fuel.
I was always curious if it was ok to do this. Good insurance in case one fails too no doubt, especially under boost.
Any downsides to external fuel pumps?
No down side to an external pump. The good thing about factory high flow external pumps is that you can score them at the J/Y for cheap. I had found a Porche Bosch pump for like $15 and two Ford F series pumps for $30. All units tested good.

That's how my Aeromotive was in the GN and he hit 8's after going to the A1200
Just something to look at.

That Aeromotive pump is a good score!
I'm not going to pull my fuel tank, it's on top of the rear end - when IT comes out, I'll mod the pickup to use only an external.
Personally i wouldn't trust bosh at all... if your gonna go get a bosh pump form a reker, go for it cuz its probably gonna be old and those ones were well made but keep in mind they are used. but I would never buy anything new that bosh makes... a few years ago bosh was high quality, now they dont give a rats ass about quality they are all about profit. aka buy a set of bosh plugs, have 2 duds... same with anything they make now day's.

I know what you mean. My 1998 F150 had the origional (from Ford) Bosch plugs in it when they were changed at 125k miles. They were still working fine, but figured it was time to replace. The next set was MotorCraft and lasted 60k before the elctrodes were so worn, that the gap had been doubled, lol. This time I put Bosch back in, and two months later one of the electrodes and ceremic tips had completely broke off - luckily I have noticed no damage.
Just putting it out there. Ive had my Walbro 255 for about two years now, roughly 20k miles with it and no problems at all. My only complant is that its TOO QUIET. My stock pump was louder. Can barely hear my Walbro

The A1000's are nice pumps. I've had problems with them overheating on longer trips in customer cars. They say right in the instructions that they recommend buying a voltage regulator for anything seeing more than 30mins of runtime, or less than 10gals of fuel.

The FPR is on your fuel rail by the throttle body. The stock FPR for that year I think is 55psi so you are fine.
