Fuel Upgrade Kit installed

[solrchrgd]

I bought a Fuel Upgrade Kit from Jim@Foreignaffairs. The kit includes a fuel filter and bigger lines to both fuel rails. The kit was fairly easy to install once I got all the right tools.

The car seemed to be a bit more responsive. I really didn't get a chance to push the car hard. I will repost after a few more days of driving.

There are some pictures on my cardomain site.

do you have a larger pump and injectors?

How much did the kit cost if you don't mind me asking?

BTW where did you get the low brass fitting from and does it ever rub?

Thanks!

[solrchrgd]

No i haven't gone to bigger injectors or fuel pump yet. They are both on my "to do list" though. I will probably go with the Walbro 190lph pump from URD.

The Fuel Upgrade kit cost $200 shipped. Jim@foreignaffairs posts regularly at the Camryman.org site.

Sorry I forgot to reply about the brass fitting. I got lucky and found it at small "hole in the wall" store. I have gone back to see if they had anymore but i was told its not something they can reorder. I should have bought more because they were only .50 cents each. If I am in the area I will stop by again and see....

im curious how much better the flow is w\ the upgrade that he offers... because im going to get the fuel pump from URD soon, and ill be running that w\ my supra injectors, and I wonder if the fuel lines would be enough to not have to worry about loss of fuel at high boost (like my 7 pounds)

[808Camry]

Is it a stock fuel filter replacement or did he modify the stock one to give it more flow?

Jim did a lot of work on this selecting high quality parts and such. My understanding is, the fuel filter flows more and the lines are larger. I thought everybody knew about Camry Man's Passing Lane, just another 1 of the good sites for Camry/Solara. It went down for a while but has been up and running again for quite some time.

Hopefully, I will be testing fuel flow on June 5th (if all goes as planned). Personally, I think it may have been an issue with Jim's filter. Jim is a very smart guy and I'm sure he knows what he's doing but others have reported no pressure loss to the front rail all the way up to red-line. If you think you have a problem, test the pressure to the front rail. If it drops to much, go for the upgrade. -JoeB

On my car I ruled out the original filter only because I replaced it. During R&D I did bump up my fuel pressure by modifying the stock fuel pressure regulator to 55 psi. I used an very high output Walbro pump and Supra injectors. But things just didn't feel right, like I was hitting some sort of wall. That's when I decided to test the fuel pressure at the front rail. I hooked up a gauge on a line that I could read as I drove. At about 3500 rpm I mashed on the throttle, and the pressure went from 55 down to 42psi, about a 27% drop. That's huge. Well I went straight to the shop and replaced the whole fuel system with way overkill. The end result was a big increase in midrange power, no more knock sensor backing off timing. I think the stock fuel system feeding the rear injectors first and then the front is a major problem, and the fuel filter is restrictive, so I put together a fuel filter and hose kit that eliminates these problems. If you test your fuel pressure at the front rail and have no decrease in fuel pressure than everything is OK with your stock system. But if you do, you should fix it.

Something else I think you should know is that I didn't put together a fuel system upgrade kit until several peopled begged me to. It is more trouble than it is worth for me to send these out, as I own an auto shop, and my time is better spent fixing cars. I just though I would pass on my experiences in the hope all could benefit, and send the stuff to use in case you are not able to put it together yourself, which many have done already. So in other words, I am not trying to sell you this to make money. I am just tired of people crying about spending several hundred dollars replacing knock sensors when the problem is fuel delivery to the front rail. If you want to put the fuel upgrade together yourself just call me and I'll tell you what to get.

Great post. Thanks for taking the time to give that very good info and insight. Thanks!

OK, I want it but is there some reason you can not post the package here?

give him a call and he will explain everything to you... hes a good guy... I have called him many many times about general stuff about my engine and parts and stuff...

[808Camry]

I called him and he pretty much just walked me through the whole process. Very nice guy!

[cdssolara]

Yes, Jim is definitely one of the "good guys". I drove up to Portland last summer to have him install his low compression heads on my car. He's done a lot of work on his car is full good information, and is more than willing to share it. Just keep in mind what he said about developing this kit more as a favor to Camry/Solara owners than a money-making proposition.

Jim,

The money order is headed your way special delivery.
