Thanks bud.

Is there a Racetronix pump below a 255lph? or, are all Racetronix pumps 255 and above? Reason i ask its according to mechanic, pump already in car it's a Racetronix but a little different than the one i bought which it actually had 255lph inprinted in it and with red casing with the words RACETRONIX... Before i tell him to put everything back in the tank and go through the trouble of reinstalling everything back in the car, i want to make sure i don't have a pump lesser than a 255lph .... Anyone?? I already asked him to ck pump to see if it had any LPH's rating on it and he said he didn't see nothing

There are two 99-02 Racetronix kits. Both look the same, but they offer 2 different flow pumps. One is a 255lph pump, not sure of the exact flow of the smaller one, maybe 190lph. Both are in the red sleeve.

If it says Holley, then it is not from Racetronix... it just may be put in their red sleeve.

If a Holley, it does not have the venturi tube connection... all Racetronix pumps for your application do.

thanks for your help.
Just went to the shop and had the 2 pumps side by side. The p.o.s one I got from the individual on this forum says, Holley HP by Walbro gss346 14903-2.
The one that was in the car just says WALBRO 12704-2 0884 by connector
PAT 4500270-5421306
same as the other pump.
the only difference I noticed was, the incar pump on one end had like a tower head a nipple and a 1/4 orifice, the pump I bought on that end of it just has about a 1" opening with a mesh filter, that's it, pump sizes are the same... help?

While the car's on the shop lift waiting for an answer, would be nice if one of you fuel gurus would let me know at least if any of those numbers from previous post mean anything? I would be grateful to an answer, thanks in advance..

The small brass nipple dentifies a direct fit pump from Racetronix.

The one with no brass nipple & a roughly 1" inlet is a generic Walbro style pump.
