    I'm looking at other places for pictures and reference, and the more I see the more I think that maybe Orion is right,,,,someone has their wires crossed at Texas Speed.

    I've looked at more of the "supposed" 99 and up Racetronix pumps from places like Thunder Racing for instance. There 99 and up Racetronix pump is the 255 LPH 600HP pump (just like I have coming from Texas Speed) but the picture on Thunder Racings site clearly shows the 1/8" nipple for the feeder valve to fill the bucket,,,,where as their 98 only pump does not.


    So I have my fingers crossed that the 99 and up pump I ordered from Texas Speed will have the nipple and I've just been misinformed.

    I'll be waiting for UPS like a hound dog tomorrow.

    And I see it has the little brass nipple for the feeder hose. Is this the 255 LPH pump or the stock racetronix replacement?

    Well would you look at this.....

    Here is the Racetronix 255 LPH good for 600 hp and the darn thing has the brass nipple for the feeder hose....this is for the 99 and up cars, and not the special stock replacement pump that I was told I had to get.



    Orion, you were right as usual bud. I don't know why Texas Speed was telling me this pump wouldn't have it.
    I gotta hand it to them though, I called them back about 4:30ish and UPS was already there picking up the days orders. He rushed it out to the truck for a next day Saturday delivery and sent me a tracking number asap. Last night at 9:30 it was getting on a plane in Texas and it was at my door here in AZ before noon. Now that's service!!!

    This pump should do the job and support all the power I'm going to throw at it.

    Yup FBJ I've used that kit 2 times now and the pumps have been good. Just be careful clamping the plastic lines down they can only be clamped once so if you develop a leak like I did you have to get a new hose lol. And fwiiww maybe I missed it but what walboro pump did you get because racetronix uses a walboro pump they just add their sleep and a couple other small things to it.

    glad you got it figured out Larry.....that accordion style hose has been known to crack and split anyhow. If you wanted to replace it you can get SAE 30R10 rated hose at NAPA. R10 is rated as a submersible hose and won't rot out like R9.

    Works like a champ. Darn thing is so quiet I didn't even think it was working at first.

    Has 4 more lbs. of fuel pressure than it used to. I think the original pump was getting a bit tired which was the reason for the change. It held 55-56 most of the time, and never had more than 58.

    New pump has a rock steady 60 lbs so it's making that regulator work.

    Yeah mine also runs right around 60-61 usually, but does go as low as 58psi. That's assuming my fuel pressure gauge is correct.

    you can either buy or build a hotwire kit for it that'll pull power straight off the alternator if you decide to mod the car very much. It'll give you a constant 14v to the pump.

    Yeah, I'll probably look into that when I swap the crate engine in there. I'll hit you up when I get ready. I just got the new rearend and exhaust done and took it for a spin today. I want to tackle the front half now but I've got customer work to do for a few weeks. At least it moves again under it's own power so I can get the darn thing out of my way
