man I hate these things... here's my story/complaints

I used to have 1 in my S4 TII...

whenever I sit in traffic for awhile.. the stupid thing would start wailing like an french police siren only slower.. WEEEEE oooooo WEEEEEE ooooo and the only way i could shut it up would be to get on open road and beat on the car... (some how boosting seemed to cure it )


so I thought it was a fluke.. and I got another one...

it's been in my FD... and i've had so many random problems with it..

again the stupid siren sounds started again.. then seemed to disapear.

I once got stranded in a restaurant parking lot.. so embarassing...

i got in.. fired it up... it was running really rough and didn't wanna idle..
I thought it was leaky injectors.. or the fact I cancelled the FPR bypass solenoid..

shut off the car.. try to fire it up again.. no luck


i thought I had flooded it... I pulled a plug they were bone dry... I realized the pump wasn't pushing...

eventually i took it all apart.. put it together again.. and it worked..


once in awhile.. the problem would re-occur.. hot rough start.. but if i "revved through it" it would be fine.. and settle back to normal...

it was ok for a couple months...

last night... i was chilling with some friends... fired up the car.. but i wasn't in it.. while standing next to the car, it was running rough.. I thought it would be ok.. i didn't rev it out... after about a minute of lopey idle... it died..

AND WOULDN"T ******* START... RROOOAARRRR


after cranjking and cranking and cranking.. it didn't work...

i sprayed carb cleaner thru the brake boost vacuume.. and the car started... by some miracle.. the fuel pump decided to take over again and start working... :S

so today.. car starts alright in the morning.. I go pick up my friend and drive back to his place... he goes in the house... while idling outside for approx 7 mins..

car dies...

and doesn't want to start!

this time the carb cleaner trick aint working... it just dies again..


STUPID POS WALBRO'S! they are absolute garbage.. I will never EVER buy another one again...

now I have to pillage my FC and take the Denso pump from it and put it in my FD..


my advice.. don't buy these crap pumps

 

This is why I use Denso or Bosch pumps only.

 

Wasnt a site giving those bad boys way at one point?

 

Interesting. I've had 4 of them in 4 different cars and never had an issue.

 

so i pretty much wasted my money..........................damnit!!!!

 

+1 for denso, installed years ago and have not even thought about it...until now that is

 

I've never used Walbro's, they die way too soon. Denso is the way to go, you can get a BNIB Supra TT pump for $260.

 

is this the correct Denso pump?

the part number is different tho..

950-0155??

I've heard that there are some poorly made copies of walbros floating around. Is this true? If so may thats your problem. I had a walbro in my G35 and in my current FD, no problems with either, knock on wood.

 

Sure is. Always buy from a reputable dealer. Probably how none of my 4 have failed or given me any problems.

I dunno if mine is a knock off.. but I did buy it from a reputable vendor..

I dunno if it overheated from running low gas..

the recent problems might be a coincidence..

but I was doing a Fuel consumption test on my car.. as my car drinks abnormal amounts of gas..

I put 50 liters of gas in.. and was seeing how many miles I could get before needing to refuel...

the odo showed 160 miles.. and the needle was a little bit of the E mark.. (less than a 1/4 for sure)

that's with NO BOOST for the whole tank.. and never going above 30% inj D cycle on stock injectors

my gas consumption is pathetic..

5.8 km's per liter?!

in my M5 i'm getting 8.X kms per liter..



i wonder if all the grannying and low fuel killed the walbro.. hmmm

 

There's SOOO many companies making "Walbro's." I've found a company that makes an excellent 255lph pump! I haven't had one problem with them. I run two of them with no problems. I think it's really who you get them from. If you buy a plastic one off of ebay for $50 expect it to last a week. I buy mine for $130 and they're great!

 

I haven't had any problems with the Walbro that's been in my car for about 5 years now.

 

Supra TT pump FTW!!

Im glad i did that mod.

 

great ******* knock-off's
i just called walbro and they said the only to check if its real is by cutting the fuel pump in half and checking for their parts. Guess i'll have to put mine in and hope for the best

 

Amen brother, I'm never looking back.

 

Yes that is still a denso supra TT pump check out Denso website. That is the exact part number I am using in mine.

yeah my walbro took a dump as well... now I got a supra pump FTW!

 

are they both 255 lph? and by both I mean the supra's denso and the walbro

 

The supra pump flows 277lph so it's higher flowing as well.

 

Technically they're 280lph

 

On an unrelated note... By this time sunday I'll be in Hong Kong

 

Bosch or Denso.

No personal experience with 7s, seen many fail on GT-Rs. I won't touch them.

 

what pump did the GTR (R34) come with stock? just curious

 

4 1/2 years 12,000 on my Walbro no problems. Directly wired to the battery w/ a relay too!
