Who has personal experience with the Bosch fuel pumps?

[turbobuick1]

I'm interested in upgrading from my stock fuel pump, and I am more interested in an in-tank set-up than external, but that decision is not set in stone. My car is largely stock, but I'd like something that will carry me to some very high HP numbers. The walbro seems great, but from what I understand the bosch can do better.

Who as installed a Bosch fuel pump? It is noisy? Will it accept a factory style fuel sock or will something need to be fabricated to adapt? I consider myself to be a competent mechanic, so any fab work needed is fine, I'm just looking for something that is quiet (or maybe can be quieted with a dampener), and damn reliable, as much so a a OEM fuel pump.

I'm aware of the Supra pump, but that is a little more than what I'm willing to spend right now, and the "notch" or tweak you need to do to the fuel pump kind of bothers me..... and I know that sounds dumb but I might give that one some more thought.

So, any guys have a Bosch fuel pump? I've seen one or two threads, but feel free to post links. Appreciate the help.

A bad production run of the Walbro's has a lot of people on here singing the rebuild blues. I, for one, have had an in-tank, bolt-in Walbro fuel pump since '05 that's still rocking steady. To my knowledge, this problem has been remedied and is a good pump into the 10's for most cars. It's quiet provided you use a new sound dampener, or reuse the stock sleeve dampener.

Either way, it's common knowledge that the stock fuel pump should be upgraded even in a TurboBuick running in stock configuration.

Thanks for the reply guys

Hmm.. I think you guys more or less have me sold on the Walbro. I understand that they had a run of defective pumps, but hopefully such a loss for their business could only make them that much more serious about quality control. That doesn't bother me, I'm know they have fixed that problem.

What about amperage draw? According to Racetronix, the walbro draws more current than a stock GM one, I wonder if anybody has any numbers on this?

I am still interested in hearing anyone's personal experiences related to fuel pumps, noise, performance, and durability.

Thanks!

I meant tweak to the fuel tank.

If you ever decide to go with an external pump, let me know as I have a good Bosch pump for sale. I wanted $65. for it, but would be willing to let it go for $50. See this thread for some pictures (post#5): http://www.turbobuick.com/forums/pa...s1-maf-big-mouth-cold-air-kit-bosch-pump.html

Thanks,

Claude.

Put on a hot wire kit for any pump you are goin to put in.. I have some old customers that still have the same pump after 10+ years IMHO Walbro hands down Oh Racetronics has a harness for the inside wiring now to. Oh we ran Bosh inline pumps for years "back in the day" .. loud and obnoxious to me BUT thats all we had back then.
