BMW SERIES 5 E39 How much fuel does it take to cover (i.e. cool) the BMW E39 electric fuel pump

Im both skeptical and confused about the requirement to keep the electric fuel pump in the E39 covered in (cooling) fuel at all times. Skeptical Did the bmw engineers really design a pump that could operate at levels of fuel that will actually damage it ... Confused If so ... then what would a chronically overheated pump look like in an autopsy So to better understand this oft-stated need lets see

matter of being COVERED but partially submerged to allow for fuel to cool it and not ingest any air. Interesting. But how partial is partial. If we answer the question of fully submerged well be a long way toward the (real) minimum level that is often recommended. Googling I found this 3-series reference which implies 2 gallons is the amount to cover the fuel pump (more or less) in the 3 series bmw.

fuel pumps on E12s and E28 very similar to E34 and E39 pumps were outside the tank so they were never cooled by being submerged. bmw moved the main pump inside the tanks to eliminate the small in-tank pump the older 357 series used. 15% or 3 gallons doesnt come close to submerging the pump in an 18 gallon tank. Arguing that submerging pump is beneficial makes no sense. fuel flows directly overthrougharound

BMW SERIES 3 E90 E91 E92 E93 Question on the fuel pump problem

Ill be purchasing a 328i in the next few weeks have done a bit of research on the site about the problem and just wanted to confirm the following -The problem affects the 335i model only not the 328i or 328xi. Different pumps presumably. -The problem appears to be ongoing replacement pumps have failed as they are identical to the original pumps that failed. To this point neither Siemens nor bmw have

BMW SERIES 3 E90 E91 E92 E93 BIG PROBLEM 335i Direct Injection Fuel Pump gone bad

My 335i coupe started stalling and sputtering yesterday. This morning it took 5 attempts to start it and then the Engine Light went on. Dealer check it out and just told me that the High Pressure Direct Injection fuel pump has failed. They wont have one till the end of next week put me in an X3. Here is the kicker there was an Identical 335i Space Grey Coupe in the service bay next to mine. I asked

This is an interesting topic. It reminds me of some historical problems with bmws (specifically 3-series) of the past. For example the 1st year of the M52 engine had plastic water pump impellers that after a time would explode and grenade the engine. Nobody figured that stuff out until later in the life cycle of the product. bmw did not make the water pump...it came from an outside supplier. The e46

BMW SERIES 3 E90 E91 E92 E93 4 Fuel Pumps in 14 months What should I do

The 2 most recent fuel pumps are the newly redesigned fuel pump (verified by product number). I dont know what to do at this point. Im worried that my car is a lemon. I think the chances of another fuel pump failure

Thank you for all the responses. Ill answer all the questions... Am I sure they replaced the pump every time they said they did Im just going by what the Service Advisors have told me and what the invoiceswork orders show. If bmw is lying to me then thats an even bigger problem. Ill take their word for it because Im sure theyre getting tired of me bringing the car in for the same symptoms (long cranks

I have never heard or read about this message before. I called the dealer and the service rep also never heard of this. I have almost 39000 miles on the car with none of the HPFP issues reported by others. Once at about 20000 miles

You can create a database from the VIN numbers of each car with the pump failure. Basically you dont need the last 5 or 6 digits which is the number of your car but all numbers in the front can tell where the car was manufactured. bmw has a several plants for the 3 series production. I dont believe in the fuel pump design failure since I think the fuel pump itself is identical on all 3 series. Maybe

If I had a second car (or was leasing) I might have gone with the 335 despite the reported problems and extremely frequent cold starts. Overall I have been extremely happy with the car and will probably go with an M3 or M5 next. bmw

BMW SERIES 3 E30 fuel pump

Last week my car wouldnt start. I did the old bang on the pump trick and the car started. A new pump wasnt in my budget quite yet so I kept on driving the car to work and back. Today the pumped froze again. A few more whacks on the pump and I was on the way home yet again. I know Im on borrowed time Anyone know how long a pump will last once it begins needing whack jobs Second the o.e.m. part a VDO

im not knocking you guys that bought used pumps but thats not a wise investment. GO to ebay buy the cheapest new pump they have and it will last longer than a used pump. got mine for 70 bucks. you dont need the screen or anything as long as it comes with the pump u can re-use whats attached to ur old pump. heck it really doesnt even need to be a bmw pump my buddy just put a 2008 WRX intank fuel pump in his 89 5 series works great

It was under warranty but the dealer said use Top Tier gas. A BJs rep called me and he said that the bmw dealer was the only one that called them about the problem.

out of it. You really need to spring for the 250 Bosch version. If you do not replace the parts on your car with good replacements it will become a nightmare for you. You will not save money in the long run. These were expensive cars when new. Buy a pump that is good for another 20 years of service. 1. It has been a very long time since OEM pumps from Bosch cost 250 shipped httpwww.ebay.comitmbmw-540i-Wag...item2a0372cd40

regulator type thing on the top of the pump that sled has listed above. A fuel damper is no longer essential when a fuel pressure regulator is involved and when the pump produces significantly higher pressure than is set by the regulator. If you look on realoem.com there are generally always two types of fuel pumps displayed one with the damper one without. Both are oem. See httpwww.realoem.combmwshowparts...90&hg16&fg05

Hello all. I just want to share my experience and hopefully add to this forum.

I have heard that the fuel pumps are supposed to be swapped out before the cars are sold. The problem for a while is that the pumps were hard to find becuase everyone needed them.

BMW SERIES 5 E39 Fuel pressure loss - had pump replaced. Its back.

1997 523 90000 miles. Was stalling on me even cutting out. Roadside assistance listened to petrol tank gave it a kick and told me my pump was on the way out. Towed to mechanic they replaced the fuel pump. Seemed to be ok for a few days now its doing the same again. Spoke to mechanic hell check out the installation and check the fuel pressure next week but suggested it might be fruitless due to the

loss return valve (under car on my years model) and incorporated fuel pressure regulator. The sucking jet pump (suction) from left side of saddle tank to right and fuel pressure regulator are less suspect but worth checking. If you are going to spend some time diagnosing this system you need to invest in a good fuel pressure gauge. I bought one from MAC tools with specific connections for bmw
