Just got my car back for doing a Cam swap..At the shop the stock pump took a **** a day after the car was done. No big deal put a new pump in it, they said get a Walbro, they put a new one in. The stock one was jumping from around 30-50 lbs when it would work. The new one holds 60 all day. With the new pump it ran a day and I drove it an 1hr or so and parked it, now I have no pump..No pressure at the rail..odd how it works for a day and then nothing..Is it a chance that maybe the new pump is bad? Checked fueses, all good. Relays maybe?

 

A buddy of mine that had a similar issue found out that the connection on the back firewall was loose... He just bent the female pins in a little so it would make good contact, not a problem since..

The last 2 years I have been thru 3 walbros, I since changed out to the racetronix fuel pump and harness.

 

Pump could be bad, but it could be many things.

There are counterfeit pumps & also a few Walbros that are not suited for your application, though they are sold as a replacement for your car by various shops.

Also there are some kits out there whch use rubber hoses & also omit the venturi system. You get what you pay for.

Not sure what you have or how it was installed.
90% of the problems are from poor install or improper application.

I've had excllent luck with the Racetronix kits I've used over the years & only sell these kits for a reason.... they work & do not cause me problems.

 

Put a Relay in it this morning and seems to be fine so far but only time will tell..

 

Do not use the fule hose they provide. It will crack and break. Get you own
