I would get something like this instead. These pumps are proven to be reliable based on the number of fbody users on this forum who have installed them.

The WS6 store is a sponsor. Give them a call. Am sure they can fix you up with a replacement for about the same price.

I would call WS6store first. If you want to see how 'reliable' a Racetronix pump is, just click through this fueling section for a few minutes.

We use racetronix nearly exclusively for all of our new products. That is how confident we are in them. Most of the "reliability" issues are from improper install or other non fuel pump related issues. Most people dont want to hear that, but it is the truth really.
Any larger than stock pump will suffer if you dont use a hotwire harness of some sort, and with that comes proper battery care and alt charging operation as well. Its an entire system.
Racetronix had nearly every part of the fuel system figured out and included in their kits. The others give you a $3 generic install kit with rubber hose and thats it and no install help AT ALL.
We understand racetronix has ALOT on their plate so ANY customer here that has an issue, please contact us EVEN IF YOU ARENT OUR CUSTOMER. We want to help you have the best experience you can whether you bought from us or not.
(Sorry for the rant)
Thanks

I will be installing the upgraded 1998 340 kit and c5 filter/regulator kit when I install my new TSP 370 LQ9.

I agree with WS6 tech about the resources and and effort put forth by Racetronix to supply the fbody crowd with products built specifically for each application. But we seem to forget that when someone has an issue as all vendors do. It's not a perfect world in the auto industry where everything mfg is 100 percent perfect.

To the OP - I would consider an upgrade to the electric wiring for your fuel pump as well if and when you decide to install a new pump. A complete plug and play kit is available for your application by year.

Lest we forget, the fbody is nearly two decades old. The electrical wire, connectors, and grounds degrade after time - especially the bulkhead connector which doesn't have the capacity to handle larger than stock fuel pumps. As Racetronix clearly states in their literature - their fuel pump life will be less than optimal if the electric power supply is deficient.

My purple racetronix pump lasted me about 2 hours. It was wired correctly. Luckily I had duals and was able to hotwire the secondary one to get me home.

I got you beat - my 340 lph lasted about 10 hours. Goes to show, you can have good luck like I did with the first 98 kit from Racetronix purchased in 2005 and then NOT so good with the second go around.

I suspect the 98 model year yellow bulkhead connector that can handle only 14 amps might have contributed to it's failure but that is just speculation. The wiring kit that came with the 340 kit was nearly identical to the 98 kit wire harness, so the blame isn't a wiring or installation issue.

Don't know if quality control is better now than when I was in IT, but the rule was that if an electronic or electrical part was going to fail it would usually fail after a few heat cycles. If it lasted more than 30 days, it was probably going to be OK.

I replaced the 340 kit with a Racetronix dual 510 lph kit. So far it is running without issue but still only have < 1000 miles on the pumps. Hindsight tells me it is what I should have chose from the get go. You win some, you lose some when we start modding these old cars.

I have had the quantum e85 340 pump in my Foxbody for over a year now and have not had a single issue. I plan on using the quantum stuff on all of my projects.
