97-98 Fuel Rail

[NITROUS]

Looking for a 97-98 vette fuel rail with regulator. These two year models have the return line. I can send mine to S&P for modifications for $165.00 with trade in but I'm looking for a better deal than that.

Just use the returnless setup. Make a "T" in the fuel line and return it to the tank with a inline fuel pressure regulator. Mine is set up this way and it works great. I'm sure GM wouldn't have made them that way if it didn't work well.

Good thinking! I guess S&P was just trying to get a little more $$$$$$ out of me. Thanks for the reply!

Yeah, that's the corvette fuel filter with the return line phylosophy. S&P markets the return style manifold stating that it is better because the fuel stay cooler and makes more HP. A returnless manifold has the fuel just sitting there waiting for use and heats up in the engine compartment. I see their thinking. If it made that much of a difference I am sure that GM would have gone back the the return style fuel logs in the LS7 and LS2s. Personally, if I were to go with the return style fuel log I would get a set of Wilson fuel billet fuel logs for just a little bit more money. I see that style for sale on Ebay all the time. You can use the LS1 logs or the 5.0L mustang logs. Just watch your prices, should not be over $200 for the complete setup minus fuel pressure regulator.

Hey Greg, They were just gonna sell me the fuel rail and regulator and tie into my existing fuel filter with the new flex lines.

Too many options are available. If you are going all out performance then the return type is the best. For a daily driver I wouldn't screw with it, just run the single supply line. Every LSx engine from 99 up is set up that way from the factory and work just fine under normal usage. Buy the Corvette fuel filter with the built in fuel pressure regulator, Wix #33737 I believe and tie in to the fuel lines where your old filter was. I simply cut both lines right at the filter and added the Corvette filter in it place by putting 2 clamps on each end of the fuel lines on the tank side. I used fuel injector spec fuel hose to join the old line to the filter. On the engine side I bought the connectors at PepBoys and ran a length of 3/8" fuel injector quality line to the engine. I couldn't see throwing money away on something that didn't seem to make much sense to me. I could use the cash on something else like a six pack or table dance..

Hey Greg, what's wrong with the 02 stock regulator? The 99 and up single supply and regulator supplies 58 psi. The corvette fuel filter/regulator only supplies 45 psi. What's the advantage?

Thanks

This is what I was going to use originally but I was told the pressure was too low.

[RedHeartbeat]

That's BS. I put a guage on mine and it read almost 60lbs at the fuel rail. Whomever told you that the fuel pressure regulator in the filter was 45 is full of it or just trying to sell you something. Put a guage on your's and see for yourself. I was using a mechanical autometer guage to measure the fuel rail pressure at the schraeder valve. If I remember correctly the later model vehicles have the regulator built into the fuel pump assembly in the tank. Another thing to possibly fail in that assembly and cost you $400 to replace yourself.

BTW, that's one nice looking setup there. Sure looks better than the cobbled up one I did. Looks like something made for a show car.
