uh yeah i just pulled the fuel pump and it said Denso on it is that OEM or not? the guy before me said he replaced it with a aftermarket upgrade, but i dunno.

 

i think the stock one is denso. What's the part number for it?

 

Got a pic of it?

 

don't see a part number just a bunch of rust, lol. Anyways does denso even make an aftermarket upgraded fuel pump? Thanks!

 

Yes, Denso has a better pump. See this site http://www.rx7.com/cgi-local/2catalog.cgi?cat=12&part=1 beats a waldo hands down.

 

man I wounder what part number that is I bet i could find it cheaper than that! Anyways I got one of ebay its the walbro 255 is that one any good? Thanks

 

oh **** just read the other part of you post damn is the "waldo" really all that bad? I mean does it work ok with a TII and is it really rich on idle? Thanks

 

dunno, but lots of people have the walbro

 

what is the part # for the stock pump ?

 

If it says denso on it all likelyhood it is oem.

 

Still, it would be nice to have a part number...

 

I believe the stock one is denso IIRC.

 

The original part number is at this site http://www.mazdaformance.com/rx7parts.htm

I don't have a vested interest in looking at micro fisch.

The Rotary Performance site says it all. Waldo is ok i guess. cheap. overwhelms the fpr etc. lots of people have them. whatever. they're probably ok. ha

 

lol, I'm with you hailer I don't often believe in cheap because you always get what you pay for especialy since I am doing a full restore of my 88 tII however sometimes when times are tough, you know. LOL anyways thanks for all the input you guys have given me I'm trying to change all filters and do the basics right now on the engine because I just got it started up but the idle is very ruff you know like 800rpm to 1200rpm, back and forth. Anyways Thanks for the help again.
