o.k. my s13 has been giving me trouble with intermitent loss of power at low rpms. I checked everything and it seemed to be o.k. untill I checked the fuel pump voltage and it was all crazy 5-9 and them back to 12 volts so I got a fuel pump from ebay and through it in and ta da!! it fixed it. I read that a lot of fuel pumps are going out because of the ethonol thats being put into fuel so if your car is going crazy mostly at low rpms and on hot days just get a $30 ebay fuel pump and try it. I hope this will help some people with this stupid problem.

yeah I know it could be other problems but im pretty sure this is the problem most of the time. the ebay pump was really good quailty it came with all the wiring and every thing like that I got about 200 miles on it and no problems yet.

its a $70 difference. ebay is $30 and walbro is $99 from frsportanyone know how much an oem one is? probably somewhere in between those. and walbro has a shorter lifespan than the oem one. have you seen the smallness of the walbro? theres a few reasons to go ebay instead of walbro. only put the walbro in if you need to, if you ask me.

That is really the worst display of misinformation I have ever seen. Where do you get that the Walbro isnt gonna last???? I had one in my 240 for 6 years and never one issue. The "smallness" of it. It doesnt need to be any bigger, it still has to fit in the sending unit...

And what are the "few reasons" to go with the ebay one... The "smallness" has nothing to do with its performance, and the life span of it, it'll last a hell of alot longer than a cheap ebay knock off version of it. I am all for saving money, but this is something I wouldnt cheap out on. Walbro has made a name for themselves in imports and have been around for a long time. Now what you have said is childish, and inexperienced. I ran a walbro 255 pump in my first civic for 10 years. You drifting that drop top and beating the hell out of it. The fuel pump will outlast the car... The ebay one, you'll be spending that money again later to get a walbro.

Let me try to sum up what the guy above me typed. Just spend the 90 bones in a reliable part and be done with it.

i never will understand why people rather cheap out and buy the knock off versions... a few months later they will make a new thread saying "NEVER BUY FROM BLAH BLAH MY THINGS BROKE" just spend the extra 60 dollars or w/e and buy a REAL dependable part.

do it right the first time

i had a walbro, lasted a little over 1 year in my car, maybe close to 2 years. from my experience, they don't last as long as oem. and what i was saying is why spend the $90 on a walbro if i dont have any reason for more liters per hour. im not goin turbo, nor doing any tuning. i'd rather get something cheap for now and inexpensive to last me til i do decide to add power. i wasnt saying at all that walbro isn't good or anything like that. they make a good pump for what it is. but in no way are they the best and i dont know how you got 10 years out of one, that's unheard of. even 6 years is pretty crazy. anyone i know that's used a walbro pump has never had it last that long. for now, i'd rather spend the $60 on an oem one. i was just curious as to how the ebay ones are since it's a pretty simple piece of machinery. and im more curious to see if the filter comes with the $30 pump so i can buy the set, and resell the pump itself for $20. it's good to have backup filters and for $10 you can't beat that. i love how you are always so quick to jump on others asses. relax guy

do you understand how a fuel pump works? not a difficult thing. some stuff you can get off ebay, i.e. intakes, and they're perfectly fine. other things, like turbos, you dont buy on ebay. you just have to think about the design, how elaborate the item is, how difficult it may be to be precise when making it, etc. the fuel pump doesnt seem too crazy so i figured i'd enquire about it. oh, and if you're lookin for REAL dependable, i wouldn't even bother changing anything from stock.

if you have 5-9 volts at your fuel pump, then you put a new one in, you would STILL have 5-9 volts at the pump. sooooo, exactly how did this "fix the loss of power"? only thing that makes sense is mabe you cleaned up the connections accidentaly or mabe the placebo affect

This line right here sums it all up, you're an IDIOT....

Stock fuel pumps cannot flow enough fuel in a swapped car, hence the reason to UPGRADE, to something better. And by better, I don't mean a $30 piece of sh*t off ebay. Spend your money wisely or send it to me, my paypal address is [email protected], Thanks in advance.

If I were to do it over again, I'd spend the money and get the Tomei FP, plug n' play FTW.

you have no idea what you are talking about and couldn't be anymore childish.

yes, if i had a highly modified car, i'd use a more efficient pump as well. but that wasn't what i was talking about before, these ***holes just decided to twist things around to bring it to this.i totally agree, if i needed the pump, i would get it.

you need to grow up. to make personal attacks on here is just pure immaturity. i never said i was getting the fuel pump from ebay, i was asking if it came with the filter so i had a way to get a cheap replacement filter. maybe you should read what i actually wrote before you make your comments. i wrote that if you wanted "dependable" that you shouldn't modify your car in any way. where in there did i say "do not upgrade your fuel pump if you do a swap or modify your car." please learn to read before you comment on what others wrote. calling me an idiot like that just makes yourself look even worse in the eyes of most of us on here.

i will give you the benefit of doubt that you did just misunderstand what i was saying when i sarcastically said not to modify if you want dependable. it seems like you interpreted as me saying not to change just the fuel pump. im not sure why anyone would ever assume that, as it makes no sense whatsoever, but i was jokingly saying not to modify your car in any way from stock form if you want dependable.

im in total agreement with you.

when it comes down to it. if you are not in need of a higher liter per hour pump and need a replacement, i would rather spend the $60 on an oem than $100 on a walbro. THAT was my original argument for all you illiterate lazy people that won't scroll up and attempt to read what i wrote. i am really only interested in the ebay one for the filter since it would be cheaper to buy that setup and resell the actual pump than buy an actual replacement filter. i was just curious as to how the ebay pump was working out for the OP, so i asked. didn't think it was such a horrible thing to ask how a certain aftermarket part was working out for someone. god forbid we do that on a car forum.

besides redoing the wiring and cleaning up connections, you can hard wire a relay in. there was a article on it somewhere if you need it, but havent personally done it

I'm sorry you said you weren't getting an Ebay fuel pump...?

You're back pedaling trying to save your image on here, but you've already screwed yourself. Stop, admit you're an idiot for buying an Ebay fuel pump and move on.

Calling me illiterate is no different than me calling you an idiot, it is still a personal attack. But, unlike you, I don't take offense to it, because it's a forum and people are going to post stupid things. Especially this posts like this "I found the problem for loss of power in are cars". Perhaps you should take more "engrish" classes man?

I simply stated a personal opinion based on your moronic posts.
