Fuel pumps other then walbro...

[1966 dart wagon]

I bought a fuel pressure gauge last night to confirm my walbro had died again, It does fine just driving around but wont flow enough fuel, I hook up the gauge, 50 or so psi, unplug vac line on fpr up to 55 then shut the car off jump the pump and squeeze the return line for it to only jump up to 70psi or so, its shot wont hold enough pressure, this is my 2nd pump, I had this same issue last year. Is e85 killing the pump, I know of multiply guys with other brand cars running walbros without problems. So this brings me to my question, Is anyone running a different high volume pump then a walbro, I know some are running external pumps, but i prefer to keep it in the tank. I was looking on summit and they had a holley and edlebrock. Not really sure if i wanna roll the dice with another walbro pile, its not a huge deal to change the pump but just a pain that I have to do it, I shouldn't have this problem!!

I have all of my fuel tables kicked up way high thinking maybe this is why I was going lean, so now running on regular fuel with the fuel though the roof it actually doesnt go lean at wot, but hey it is dumping all it can.

Thanks for the input,
Jack

Is e85 killing the pump

Tried to drive out of town with it today, got a couple miles out of town and it went insainly rich, im talking 9's for afr.

Got it back home, it was stumbling at any constant throttle, afr at idle were perfect at 14.7. Got home and checked fp and all that again, same issues except when I removed my gauge i noticed the shrader valve on the fuel rail was filling up with gas and dumping over, I soaked it up with some towels then it filled right back up again, so I'm going to change that to a different one I have laying around, I noticed it wouldnt leak at all once I put the cap on it though, weird.

I've tried these guys, had good luck with a customer's car using one. When my current pumps fail, going to get some of these-

Silent pump, cheap to buy and when I want one for another car, I just walk two doors down from the shop and buy it without paying tax

In at least 4 cars. It's a *very* quiet pump

Good info. I used the large Bosch copy inline pump on a buddy's car, wasn't THAT quiet but did it flow, damn.

I see they only list 91-93 daytona isnt the fuel pump/carrier different on those, will this go into a stock 89 tank/assembly, looks different.

Have you been buying genuine walbro pumps? sure there not knockoffs??

I checked, looks like it. You can make those pumps work with a bit of work.

The real Walbro's are having issues, there is a thread on it.

Yeah, they have that little 'siphon jet' side port that fills the container-within-the-tank that the later Daytonas have. You *have*to use that jet style pump in an RT or an SRT but in my mind, it will also work fine in a standard baffled tank. I have them in two or so Masis and the Rampage and they are working fine. One thing tho, the plastic casing inside the RT is so 'fuel tight' that I had to cycle the key like 25 times before the pressure would build

I've been getting my walbro's from chris at TU and as simon said there is a thread going around about faulty walbros, made me feel like I'm not the only person having this problem.

Anyone run e85 though the pumps on ebay?

are you talking about this pump:

I see they are all the same pump, they list all the same applications. So how do I modify this to work with my style sending unit/pickup???

Well, it's a smaller diameter than the stock pump(but aren't they all?) so you have to use a rubber spacer if you are using the stock sender assy. I used an old section of radiator hose slit along the axis. If you have an early (non RT or SRT) just put the rubber hose on the outlet nipple on top of the pump, hook up the two wires and secure it in your stock hangar. Done. If you have an RT you use the top "cap assembly" (its in the pic but barely visible) snapped in place over the outlet and everything else hooked up on my 93 RT. Every aftermarket pump I've used needed some kinda mod to adapt to the stock hangar/sender...

ah so hook it up as normal like a walbro and ignore all the other stuff on the pump pretty much?

I'm using Walbro's in 2 cars with no issues one is dedicated e85 drag car. All of the ones I am using are at least a year old. Is the problem related only to the ones that Chris is selling? The ones I bought were off of Ebay from this seller: http://stores.ebay.com/Full-Throttle...=p4634.c0.m322

Both of my bad pumps were from chris, but looking on other threads, walbros have been going out on people who have bought them from other vendors too

I going to go ahead and order this one and see how it goes:

OK,

So which one of those TRE pumps would be easiest to adapt to my 89 turbovan?
From the pictures all the applications seem to look the same...I'm guessin' they are.

TRE-377H looks like the one...eh?

Thanks,

For the price and reputation I would not use anything other than a genuine Walbro fuel pump. Its your engine we are taking about.

I have been using Walbro pumps for over 7 years. I have had only 1 go bad that was 5 years old. It was just acting sluggish so I replaced it. It is now in a non turbo car with over 20k more miles on the pump.

There are a lot of knockoffs. TiAl has an advisory out and so does Walbro.

The genuine Walbro pumps do not seem noticeably louder than OE pumps.

My guess is that E85 may be damaging the pumps. Many studies have found that E85 is not all whats it is cracked up to be, and that includes ruining fuel components.

Here is a way to tell if your pump is genuine Walbro
