|
|
Hi,
Since doing my sender the fuel pump sounds quite noisy. I have a horrible feeling this is down to the path of the supply hose.
The new sender had it's nozzle facing forward instead of back so used a longer hose, but I have a horrible feeling the tightish bend might be resticting the flow and hence the pump is struggling and so making more noise.
Anyone with a 16v or ie, can you have a listen to your pump and report back please?

Hi John,
When I had interior in my car and it was running low on petrol you could hear the pump, otherwise it was not noticeable.
Could you replace the pipe for a longer length and upgrade it at the same time.
I have heard that the pumps last about 15 years then start to fail. _________________ x2 33 16v

Thanks Al'.
It used to get noisy when low on fuel like yours, but now sounds about 1/2 as noisy as that with half a tank.
Have you changed your pump for a juicier one for your hot engine?
I think I might have to get a much longer bit of hose and try and run a soft curve around the top of the tank which means dropping the mofo yet again- grrr _________________ If it aint broke, fiddle with it until it is!

The fuel pump my 33 had from new, lasted around 15 years, the second one failed within 5 years. The first pump started to make big noise which could be heard inside the passenger compartement so I replaced it before leaving me off the road. The second one failed with no warning ... one fine day it stopped running and I could make it run again by tapping it with a hammer until I got a replacement pump. Now the 33 is counting the third pump within 21 years. _________________ Thanassis Gritsopoulos

I think it was from you grit that i heard they last about 15 years
John, nop, I asked about it and was told it's not needed, sweet, my injectors are supposed to run at 3 bar and doesn't need a remap at 3.2 which mine is at, basically no vacuum controlled FPR = 3.2 bar. I would like a swirl pot though _________________ x2 33 16v

Took the car to get some odds and sods from Wickes yesterday evening.
The pump was noisy again, then it went quiet for about 3 minutes and just as I got into the Wickes carpark it lost power and went lumpy.
Came out of wickes- pump dead
After almost 2 hours recovery man arrived and tapped the fuel pump with a spanner and the car started and drove- quiet pump.
Got 3 mins from home -loss of power - cut out. Called recovery mans mobile and got trailered the last 3 mins home as pump shot.
First time in 11 years the 33 has ever left me stranded.
I think my hose route is probably restricting flow which the old pump struggled with, then died.
New pump on order, and will sort the hose routing somehow-
John

Hi John. Glad you're still alive mate!
Got any plans for your beast then or is she going to spend her last days in the garden as a piece of automotive sculpture? |

Hi lee
Well we moved to a bigger house which in turn means a bigger garage
So the 33 will it's own space and will never have to sit in the rain again so once it's built then I can start restoring it and making it faster _________________ WODA WE NEED? MORE POWER!!

Nice one. I moved house last year and have been non stop doing it up. Need to put some time aside to do some jobs on the 33 but the missus keeps cracking the whip! |

Fitted the new pump today, and it's by no means silent running, but the old one must have been slowly dying as the car is transformed! It 's pulling like an express train, running the best i can remember for ages, i'll worry about mpg later...
Mine was one of the blue ones off of ebay, £40 all in. If you get one Lee, please report back about the noise.
BTW- I assume the pump holder clamp thing was originally somehow bonded together as mine has come away at the rubber cups (if that make sense) and there's no way of reattaching short of "no more nails. Made it temporarily secure but will need to sort.

Will report back John. Are you sure your rattling isn't because the rubber jobbies are knackered and the pump is vibrating against the side somewhere? |

Wow........ Total transformation. Car pulls much harder with no hesitation and idles nice and smooth. Pump is quiet John, only the slightest whir of the motor which you can only notice when you stick your head up in under the wheel arch. Old one I could hear inside the car!
Why didn't I change it many years ago? |

Yeah Lee it makes a big difference doesn't it?
My new one is slightly noisy but i'm gonna try not to worry about it too much
Shouldn't have any real restriction on the hose from the tank now and the filter at the other end has probably only been on for a few thousand miles... _________________ If it aint broke, fiddle with it until it is!

Might be quieter John when you sort out the mounts. I replaced mine with small exhaust mounts. |

Hi,
Pump whine = restricted fuel lines, most of the time between tank and pump.Clogged in-tank sock filter, pinched or bent fuel hose might be worth looking at.
Also inspect the fuel pump inlet with a flashlight, there is a filter inside the pump and it might get clogged by crud or rust debris from the tank.
regards,
