I've been running a Bosch External for about 12-13 years. I just pulled out my in-tank pump when it eventually crapped out. They were mounted in series. My Bosch pump is a puller, I don't need another pump to help it. Just make sure you mount it at least level with the tank. I have mine mounted at about the bottom level of the tank. It makes it easier to pull.
I believe all the external Bosch's are pullers. Steve has me confused at this point as to whether they all are!

It doesn't matter anyway, as it's been purrrrfect for all these years. Road racers use these pumps a lot and call them 5 bar Bosch pumps. I've heard that they are rated at around 54-57 gallons @ 70-72.5 psi; maybe as high as 90 psi. My pump is a #216. Inside the tank I just used FI hose and a stock filter attached to it at the bottom of the tank. The filter is mounted vertically, so some of the crapola drops back into the bottom of the tank (hopefully), when the engine is shut down.
I've been running without the prv valve for about 3-4 years, ever since it went out. You really don't need it, since I can hit the starter before the relay stops and it will fire in a few cranks.

Well I'm pissed! I got back to the shop after work, and the idiots had put an ac delco E-3211 in the tank! The boss (my buddy) said it would have been a lot less money to put the in tank pump in, and the parts guy told him it was an 85# pump.
Well the afpr was set @ 35# when I got there. (old pump pressure setting)Turned it way, way up to 42# taped the fp guage to the window, and at WOT, 10 psi it merely holds steady.
Question now is will the bosch even work, or is the in-tank pump a restriction? I'm guessing it should be ok....
Then I will need to find a place to put it, that is not over the stock muffler.
Grrrr. I'm not even going to back over there now (next door). Things would get ugly 'cause even though we are good friends, I'm too riled up at the moment to trust myself.
On second thought-screw it! It's time we went out and had a few beers together. I'm not ALL that out of control.

Yes the customer is always right, 'cept when the foreman thinks he knows more about Turbo Buicks than I do.

The tank is comming out, and Red's XP is going in, along with his volt booster. I've never heard of anyone having a problem with either...
Guess I could sell the Bosch. Anybody here interested?

Not being one to waste money, I'm going to wire the volt booster so at WOT, my windows will roll up and down a bit faster.
Go buy yourself a relay and hot wire the windows...
All the volt booster can possibly do is add some more pop to the ignition which should not be needed but might help on some cars. Us old guys watched Conley run 7s on a stock ignition with no boosters so we doubt some things...on the other hand, John Spina has said it has helped some he has seen.
The pump flows enuf, Walbro 340,at 12 volts to go way into the 11s, and with a hot wire and seeing 13.5, into the tens. You don't need any more stuff that might fail.
I guess you might get brighter headlights, but again, just hot wire the lights....
