Look for the "vin 7" pumps. I may try one of these...

We experienced several Walbro failures on pumps we installed between March and July of this year. I don't have the exact total number, but it was more than 6 pumps, possibly 7 or 8. The worse news is that this accounted for EVERY Walbro pump that we installed during this time. Most of them failed within a couple weeks. We purchased these pumps from a reputable vendor.

Chalk up another one!
Started last night. FP went up to around 50psi (max) @ 10psi boost! (44PSI base)
I was running close to 21 PSI boost on my DD tune and saw 3 degrees KR.
Thank GOD for Alky! It saved my HG/motor!
Guess I should not complain. My pump is one of the "small % of accepted failures"! Anyone who downplays this issue need to get their head out of the sand!

fuel pump failure!!!!!!!!!!!!!!!!
Hey guys got my walbro kit from full throttle on 3-25-08 and finally installed it on 5-12-08 so that makes it about 4 months old! Took a trip with the family to naples this weekend and barely getting out of alligator alley, DEAD PUMP!!!!!!!!!! I cranked the FPR all the way down and managed to drive to a hotel 11 miles away 3-4 miles at a time allowing the pump to cool in between! My great friend NO NOS packed up his truck that same night and drove up with jacks, tools, lights, etc and helped me change the pump. THANK YOU AGAIN NO NOS! I had to buy the crappy replacement pump from advance auto to be able to get home!
Will full throttle do anything for us?

I am doing everythig I can for you, which is working with Walbro to figure out why some people are having problems. I spoke to them today and they have assured me that they are working on this and some engineers are going to meet this late this week or early next to discuss what they have found so far from the few pumps I have got back and sent them (about 15). I would recommend you send that pump to me ASAP so I can get it to them. That is the only way we can fix your problem right now. They need to see failed units to find out why they failed. 15 out of thousands is not a very good sample

It now appears that I'm another victim of the Walbro pump saga. After a 3hr run to Charlotte (Lowes Motor Speedway--Auto Fair) Sat a.m., my car/pump died (in traffic on Speedway Blvd non-the less!). After 5-10 min (3 traffic- light-changes & lots of pissed-off fellow "car enthusiasts" later) cooldown, pump/car finally restarted & I was able to get car into Speedway/ & parked w/ Southeast GM Turbo 6 Group Display. I was then OK for several more trips--about 30 minutes or less each--4-5 hours later that afternoon. Didn't move car on Sunday.
Today, Monday, returning from Charlotte to Myr Bch--car craps out again after 2hrs & then 6-more times in remaining 1-hr to get home. Last 3 crap-outs, car/pump would only run about one minute after a 3-5 minute cooldown. Seems like it is a cumulative heat buildup problem.
After finally home in driveway (coasted-in w/o pwr strg or brakes ) I tested 3 more times, w/ FP gauge laying on windshield: FPmp would not come on w/ ign sw until 3-4 min cooldown from prev stall, & then FP & engine would would start-up OK & idle about 1-2 min before FPres would start droping, FPmp would soon stop running & engine stall-out prontito...
My remaining question is whether a bad FPmp relay could create problems like this--cause this to happen??
[For the record, my pump/kit (834GMHP) & Hotwire Harness, purch from Mike/FTS also, was installed about 2-years ago.]

Here's a little piece of information I received about Walbros just recently.

I've been into these cars since about the time production of these pumps was shifted over to TI and have never had a good Walbro experience. Was hoping things were going to turn around for me when I had a fellow TR owner tell me that Cottons Performance sells the good ones, so I ordered one of those. The pump may be a good one, I don't know for sure, but it looks identical to the last 3 I have had crap out on me so I'm afraid to install it. It too is the F200000169, has all the same markings, came with all the same stuff etc. He says he hasn't had any reports of failures with the ones he sells, but it's absolutely identical to the other 3 I have had go out on me all from reputable vendors (2 from G-Body, 1 from Full Throttle) so I'm gonna send it back and just keep using my TTA/Syclone Pump. I've done this pump switch out procedure 3 too many times now to take the chance again when the one I have is working fine and meeting the demands (knock on wood).

I know right......
were my thoughts too when I received this info....Not to say that is or isn't the problem, I'm no expert on fuel pumps and I don't know much about how they work or how it all comes together, but my common sense thinks how the heck could an inlet cause all of these failures??? and the real question is, is it just limited to the F20000169s or is it happening with the 340s, 341s 342s etc too? cause if it's happening with the 340s and the others they make than the issue is beyond the inlet. I've apparently never had an actual 340 eventhough I thought I have all this time since they all have F20000169 stamped on them.- Joined

I still have a bad one in the tank. When I get it out, I'm going to disect this sob and see If I can't get to the bottom of this. :wink:
My Walbro that craped on me was bought from Poston's. Poston's made good on it and sent me another one
Kudoos to Poston but, I'm like T-Top.....afraid to even put it in since my EP-381 from AC works great. By the way I can't see anywhere on the pump marked f200000169 or any # alike.

Is there anything special that needs to be done to run the TTA/Syclone pump? Or is it a drop-in replcement? and what brand is it? (part number etc. if you have it)
