I am currently shopping for a new mechanical fuel pump and I am looking for suggestions. The last two that I have used have been the Carter M6866, which seem to last 2-3 years. I would like suggestions on other brands, or the nicer Carter units. I am looking for 5.5-7psi units which do not require a regulator. What about the higher priced Carters, MP, Edelbrock or Holley pumps? I don't mind raising the price from my current $33 Carter as long as I am getting a good unit. http://www.summitracing.com/parts/HLY-12-360-11/ http://www.summitracing.com/parts/EDL-1720/ Carter M6902: http://chucker54.stores.yahoo.net/cam6sumefupu.html Thanks

Mc, I am currently leaning towards the Carter M6902, which has the replacable diaphram. Thank you for the reply.

Me too, I used a cheap parts house Airtex? pump on a 360 SB (9:1/2bbl) circle burner (class rules-stock pump required) with 5/16" line and NO fuel starvation at 6200 RPM WOT though I am going to drill out the nipples to 3/8 & 3/8 line

this is the pump i would use. 3 valve and can be taken apart. the diaphragm is replaceable if you can find one. the mancini rebuild kits are junk!

I received and installed the Carter M6902 from Mancini last night. I noticed right off that the strength of the spring is much stronger than the spring on the Carter M6866 (one piece) unit that I pulled off. The description of the M6902 pump shows 5.5-6.5psi but my mechanical gauge was showing 7psi plus/minus 1/2 or so. I was watching my float levels and they were right where I set them and my O2 gauges looked good, so the extra 1psi does not seem to bother my floats at idle. I should be able to test drive it this weekend and hopefully this was the reason for my erratic lean conditions that developed out of no where. http://chucker54.stores.yahoo.net/cam6sumefupu.html

Made In USA! The 6902 shows up in the beginning of the casting part number on the flange.

The pump was the problem. I no longer have the lean issues and my A/F numbers are steady again. Thanks for the suggestions!
