Hello all, my fuel pump died 3 weeks ago and i replaced it with TRE performance pump the 255 LP one. i installed it back, cleaned the tank and replaced the filter. everything was fine until today. it died again!! that's less than 2 weeks of use. i just messaged TRE and am waiting for a reply. my question is should i try my luck and use their pumps again? or go with a Delphi pump? i don't feel like spending 200+ for racetronix on a basically stock car...and i dont want to replace pumps every 2 weeks! ideas??

PS: i live in middle east, am shipping all these parts across the world so my options are limited. thanks!!

 

Do it right once and go with the hotwire kit and a racetronix pump it will save you money in the long run especially on your location.

 

With your mods id go with the Delphi pump

 

Check all your electrical connections. If the pump is not getting ample volts & current it can burn out the pump. Inspect for any discoloration on the pins or plugs. This could be caused by a bad connection. Dirty connections can reduce the voltage. Make sure the grouns are in place and clean.

Also after replacing the pump before you run the pump add fuel to the tank. The higher the fuel level the easier it is on the pump.

Good Luck.

 

The failures will be due to inadequate wiring. Certainly not a fault of the pumps.

 

Ive replaced the fuel pump 3 years ago with an OEM full assembly pump. on inspection i found a black spot on the connection of the fuel pump but it ran fine for 3 years. this time i didnt find anything aside from that same spot. what do i check for? whats the voltage for the fuel pump? and what connection to check for?

how do i make sure? i checked the whole wiring prior to installing it and everything seemed to be fine. didnt check the readings thought. but is it impossible for it to be simply a bad pump? am going with a trap door today and see what i can find. keep the info coming please.

 

i know its best to go with racetronix but as i said 200$ is a lot for me to spend on a pump right now specially on a basically stock car. it will mostly stay as is for the next coming 2 years until am done with my studies then i might pop a vette or rebuild engine.

I couldnt find a Delphi replacement pump and after some research ive found TRE looked promising, and since delphi assembly lasted almost 3 years i thought id give TRE a try and i wish i havent.

 

seller replied. he asked if i could hear the pump noise, he asked to check fuel lines although i already mentioned that the pump was not priming...he also asked if i have enough fuel in my tank lol

 

These new breed of pumps draw huge amounts of current. The factory wiring is not adequate. So if you did not wire in a new and dedicated supply for the pump it will lead to problems.

 

I took the pump out just now. i inspecting all the connections and nothing seems to be wrong!! if you're saying wires arent adequate then atleast it should burn a fuse right? or cut a wire? or do you mean the fuel pump is getting less current and that affects it's functionality? i feel lost or maybe i picked the wrong brand.

how hard is it to wire the whole thing? am going to ship it back to USA and see what happens luckily my friend is flying to USA tomorrow so i could save some $$. what to check for while everything is out? thanks and sorry for the long replies.

 

No. the wires may show no signs of damage, but it's all about volt drop.

Wires that cannot cope with the load on them will cause more volt drop. Less voltage to the pump means less flow, higher current and more chance of burning the pump out. This doesnt mean the wire will get hot enough to melt or burn though

But if the wiring system was designed to cope with 5-7Amps and now you're trying to make it carry 15A, clearly it will cause problems.

 

makes sense now! thanks. now how do i wire the whole thing? ill try to do it while the new pump arrives. thanks a lot for your help.

 

If Racetronix or similar offer a complete wiring kit, that may make sense to use it.

 

thanks, ive found it online and I think am going to order one.

TRE replied and was VERY helpful so far. hes going to send me an RMA number today and start the replacement process.
