Title: Fuel Pump dying
Post by: Steve Wood on June 06 2011, 04:19:07 PM: That F series of Walbro pump that I bought right before the wave of failures became known decided to die on me just after I got back to town after a 100 mi roundtrip this morning. I used the alky test button to make it back to the house.

After it cooled down, it started working again tho the pressure was down about 3 psi.

I guess that was why it was looking lean at idle on the 02s this morning.

I decided to replace it with the Deatschwerks pump that came on the scene about the first of the year. Nothing ventured, nothing gained.

Post by: motorhead on June 06 2011, 07:10:28 PM: The Denso Supra pumps will do the job too.

And Steve is right, gotta stick your neck out there from time to time...

Post by: Steve Wood on June 06 2011, 07:59:30 PM: all the ricers are selling them...the Denso was a good pump, but, when you looked at the specs, it put out the same as the walbro at high pressures....t he Deatschwerkes does not drop off and puts out more there...maybe 15% more...probabl y gonna take a retune at wot...that's a good thing

Post by: Steve Wood on June 06 2011, 08:01:58 PM: the denso takes a little manipulation to get it thru the sending unit hole.

I was going with the denso, but, then saw all the discussion about this one.

Reliability counts!

Mike, I would like to think I was prudent, but, I put my neck out and ordered an Eastwood plasma cutter....LOL

Post by: gordyzx9r on June 06 2011, 11:17:54 PM: I had an ATR pump for 7 years and we thought it was going out and had one of Red's pumps put in last year. I've been told it's just a Walbro that he's tweaked. I'm kinda kicking myself for it now, especially after being talked into his Volt Booster and then being laughed at by someone *cough* Steve *cough* until I ran out to the garage and tore it out and stomped on it.

Post by: Steve Wood on June 07 2011, 09:12:36 AM: Red just sticks a piece of wire in the bypass valve on the end of the pump to shim the spring so that the pressure does not fall off at the standard opening point. He used to grind the numbers off so you could not see what standard pump he was buying and reselling.

Yeah, it really is about the reliability factor. I'd rather use 2 undersized, but reliable pumps than one super-sized unit that'll leave me driving home with my finger on the alky test button. The DW unit looks solid.

I use an entry-level welder far beyond its designed capacity... So, I am sure you can milk that Eastwood PC pretty good too. Just burn it out before the warranty expires. ;)

Post by: Steve Wood on June 11 2011, 08:13:35 PM: so I drop the tank, stick the pump in after a little modding, install the tank put some gas in it and nothing happens.

Okay, something happened...a lot of F bombs bouncing off the walls...

Thought I should bought the Denso.

Finally dropped the tank again...always fun when the gas is sloshing side to side...

Pull the effing pump out and noticed that the connector was not pushed all the way in....voila!

I need a keeper...
