racer88 Posted February 19, 2010 Share Posted February 19, 2010 I have looked at many different options for fuel pumps to install on my n/a 260. it has a 280 engine with mild cam large valve E31 head, headers ,hei ignition and su's. I know that the pressure for the carbs needs to be around 3.5 psi. Does anyone know what volume the pump needs to put out. Some are 30 gph some 72 - 150 gph with the price going up the more gph. I don't mind spending the money but do not want to waste it, as I have a paint job coming up and we all know what that costs. I have searched for info on this matter with no luck. The car is going to be a street car only but a spirited street car. Bob Quote Link to comment Share on other sites More sharing options...
Pyro Posted February 19, 2010 Share Posted February 19, 2010 use a stock efi pump with a return style fuel pressure regulator that can be adjusted down to 3.5 psi. aftermarket pumps (holley, mallory, carter, ect) tend to wear out after 1 to 2 years. The brushes on the motor wear out. The stock efi pumps last for years and years and years. Plus are quiet. So, spend your money on a good return style fuel pressure regulator (Aeromotive, summitracing .com) and use a stock efi pump (new or used).

Dtsnlvrs Posted February 19, 2010 Share Posted February 19, 2010 I have had great success with the Facet pump http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=PUR&MfrPartNumber=PRO60SV&CategoryCode=3339K no regulator required if you use the factory fuel rail Quote Link to comment Share on other sites More sharing options...
travie319 Posted February 21, 2010 Share Posted February 21, 2010 (edited) I have had great success with the Facet pump http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=PUR&MfrPartNumber=PRO60SV&CategoryCode=3339K no regulator required if you use the factory fuel rail The Facet pump is little over priced and cheap in my book... I think he would have better success with a #12S Pump from Mr. Gasket. http://www.mr-gasket.com/ProductDetails.aspx?modelNumber=12S&productID=1392&majID=225&minID=2255&selection=6&minselection=1 It's smaller in size and provides better fuel delivery, and best of all it's cheaper @ $44.99. Also a stocking item at Oreilly Auto Parts. (The pump also includes a fuel filter.) And if you want to stay away from a regulator try part# 42S http://www.mr-gasket.com/ProductDetails.aspx?modelNumber=42S&productID=1545&majID=225&minID=2255&selection=6&minselection=1 Also $44.99 and stocking...

I would not use that specific pump, the LOW side of the pressure range is on the HIGH side of what our carbs need. Mr Gasket may make one with the right specs though? The Facet I mentioned is quiet and reliable. Had mine mounted at the back of the car for 4yrs now... three of that was driving around Vegas in 120deg heat, after the Holley fried from the heat.

I have a pressure regulator so any of the pumps suggested will work. my only concern was noise and how many gallons per hour was needed. I will shop the local suppliers and see who has the best deal Bob Edited February 22, 2010 by racer88 Quote Link to comment Share on other sites More sharing options...
