Title: Fuel Pumps - Need Some Info
Post by: bmwman91 on April 12, 2010, 02:58:06 PM: Does anyone know what flow rate the stock pump is rated at?

Also, can anyone recommend some higher rate pumps that fit our cars? I am having a hell of a time finding information. Are there any standards for fuel pump sizes like there are with injectors & other common car parts? Thanks!

How long have you had it? I was just looking to get a new fuel pump and this is MUCH more affordable than OEM.

Post by: bmwman91 on April 18, 2010, 02:09:29 AM: I have been doing some reading, and I am a little weary of eBay "Walbro" pumps & the TRE ones. The one I like most is the Bosch 0 580 254 040 unit, but someone on r3vlimited sait it wouldn't fit in. I know that people have to modify the bracket to get the Walbro 255LPH one to fit, so I was wondering if the Bosch one was the same.

I have also seen people add fuel surge tanks to help reduce the transient pressure drop when you snap the throttle open. Anyone added that?

Post by: Voluted on April 21, 2010, 02:29:35 PM: Ive had a generic ebay pump in my car that was listed to work on e30s for 3 years now (60k km) with no problems. I took the old pump off and replaced the valve/connector with fuel line and used SS clamps to tie it down. It nearly touches the bottom of the tank and it seems to work great.

Post by: bmwman91 on April 21, 2010, 02:50:07 PM: Well, thanks for all the help & suggestions guys. I am going with a TRE Performance 255LPH in-tank pump kit. A lot of people have reported that the Walbro one is sort of loud, & I really don't need that nonsense.

When I install it I will try to snap some shots.
Title: Fuel Pumps - Need Some Info
Post by: bmwman91 on April 21, 2010, 04:36:58 PM: Hmm, one additional quick question.

Anyone know where I can get high pressure fuel hose that is rated for in-tank / submersible use? The regular high pressure stuff is easy to find since it is the normal stuff. I read that you definitely should not use it in the tank though.
Title: Fuel Pumps - Need Some Info
Post by: 1991 E30 M42 on April 21, 2010, 04:57:58 PM: The pump will probably come with a short piece of hose and yes the walbro is LOUD but nothing a radio and a heavy right foot cant drown out.

Post by: bmwman91 on April 21, 2010, 05:08:34 PM: Haha nice. A couple years ago I would it wouldn't have been an issue. BUT, tastes change & I ended up putting in all stock bushings, installing sound deadening on every square inch of metal & all around want the quietest ride possible.

If the TRE unit craps out though, I am going genuine Walbro or Bosch.

Title: Question on Walbro 255-Fuse?
