Fuel Pressure Regulator Advice

[Gollum]

I'm posting this in the non-tech section because I thought I remembered seeing somewhere that ebay auctions should be posted here. Well, at any rate it's not all that "technical" of a thread I guess, so hopefully this is a good enough place to park this thread.

 

I'm looking into buying an adjustable FPR in the near future, and as some can probably guess, i'm looking for the cheapest one out there that will get me by. I'd like to get one with an intergrated guage, so I don't have to bother with installing one in line.

 

Budget - Less than $50. I'd idealy like to keep it under $30 but that just not gonna happen.

 

Here's the units I've been looking at one ebay, if anyone has any comments feel free. I'm going to go ahead and list my notes of what I think of them from my point of view.

This one looks decent, but seems to come with the least amount of hardware/fittings. I'm not a fan of colors... My prefference is Brushes, then black, then chrome. All other colors are just as undesireable as the next.

I like this one, but I don't like that I'd have to bid on it, and win with the entry bid in order to get a price I like. (i'm ordering these links in price assendeing btw)

Looks like a good value, but it's not like I have a lot of experience here.

This one listed that it comes with "all hardware and fittings" but they're not shown in the pictures, so I guess it's a crapshoot.

 

So if anyone has a comment about any of these FPRs, lets hear them. If anyone has another FPR that they'd recommend and is a reasonable price, let me know about it.

It all depends on your application. Are you running a carb, or fuel injection. Then are you using it with a turbo where boost is a factor. The ones you were talking on ebay to me are not name brands so if you have issues / need to be rebuilt you might have a problem.

 

On my supercharged / boost application I use the areomotive retirn style boost sensitive regualtor. It is expensive. I have a bunch of old holley regulators that I can give you one if you pay the shipping, but no fittings or fuel gage will come with them. They are great for carb applications. They accept 3/8 npt fittings.

 

Hope this helps and let me know if you want one.

Ok, I should have specified, sorry.

 

L28ET - stock

 

Stock EFI

Will soon be stock injectors (has the L28E white tops rightn now)

Stock boost levels.

 

The stock fuel curve isn't really bad, and as long as you have the right size injectors increasing fuel pressure per psi isn't needed unless you're going to be running double the stock boost. From the dynos I've looked into, the main thing making the L28ET go lean under boost is injectors that are running out of steam.

 

I don't plan on getting an intercooler for a while, so stock boost levels will be what I'm tuning for. The main reason I even want an adjustable FPR is so if I'm running at the track I can tune WOT conditions a bit better, and then when I'm cruising the streets I can lean it back out for better MPG.

 

I'm also hoping that when/if I get an intercooler, bov, maybe even a newer ball bearing type turbo I can have the ability to swap injectors and use fuel pressure to tune it or 10-14psi. I don't really see myself going with more boos than that really. This is going to be a 95% street car, and I try to stay out of trouble on the street.

I have been doing a lot of searching and studying to prepare what I want to buy according to my goals of my swap. I have found that the stock FPR is good, but if you are looking for more then tying in a Rising Rate Fuel Pressure Regulator is the way to go. Bernard (I may have mis-spelled his name) had stock injectors and added a BEGI RRFPR to his fuel system and it helped the injectors from running lean under full boost. If you search for BEGI they have a website of how to find a real BEGI unit on ebay. Expensive, but very good. I hope someone else can confirm what I am saying, and I hope this will help you.
