    50-ish is for stock idle, up to 65 for WOT.

    Look into a Walbro 255 or something similar. Bosch makes one too, but can't remember the #.
    Gone, but not forgotten!

    Smile update

    the pump I bought makes 72.5 psi at 39 gph. Paid $169 & tax. Made in Czech republic. Bosch is nice stuff. I bought it in Stockton at Global Auto parts, any part store that deals in euro car parts. I want to run the return line as i bought all the stuff. I am going stainless. Would like to put the 2nd filter mid way in the frame. Need to figure fittings and a filter. I like the inline type like the newer gm trucks. I would like a common filter ,so down the road they will still make it. My pump sits out of the tank in the rear between the new tank and bumper. I am making a bracket / heat sink to help cool the pump. Billet aluminum with cooling fins. All for now, Alan
