iv heard about alot of people running holley blacks on them idk how long they last running diesel threw them. my friend has one on his truck its been on there for 2 years and its still going. its running about 9 psi and as long as you dont go over 15psi you will be good. i think the holleys are regulated at about 10-12psi.
No they are rated at 14 psi from the factory, non regulated, and i think it's 120 gph at 12 psi, and 140 gph at free flow. every now and then mine will hold 14.5-15 at idle on a hot day after i have drove it a while. i have a mechanical fuel preshure gauge from summit. holley blue pumps are 120 gph i think and maybe a little lower psi, but not shure on that.
Holley black pump, 3/8 rubber fuel line, a bulk tank filter head from a farm store and you will need to neck it down to accept a 3/8 nipple and build a bracket to mount it, /with a 2 micron filter, i have mine on a toggle switch but thats very dangerous, if you forget to turn it on you smoked your I/P, i would recomend putting it on a power point thats energized with your key. sorry thats the only pic i have right now i'll need to take some more.
Hey man i just reread my post it was not that cheap, i think it was $135.00 on sale, sorry bout that, i bought a walbro just before i bought the holley and it was $85.00, when you get to be a grandpa you can use your age as an excuse.:S:
I have a Walbro 392 and a Mallory 4307M regulator. Regulated at 16psi BEFORE the filter and drop to 14psi at WOT on stock lines. This is also the pump PULLING the fuel to the front drivers side fender.
The holleys like having the pump right below the tank as close as possible. They are gravity feed lovers.
do you have to run a 2 micron filter? I want to make a filter a fuel setup kind of cheap. I was going to use a 140gph pump, but need to figure out a good filter to run before and after the pump. I have a 10 micron for a bulk tank I was going to run before the pump to keep it from getting messed up and then need something afterwards.
An email to Holley got me paranoid; they said that Diesel isn't good for their pumps and they'll fail. I know it runs counter to lots and lots ov posts from folks running them. I got a Carter 4601 for my 1990. I powered it with a relay that is tripped off the IP's 'on' valve so the pump runs with the key. I mounted it on the frame right across from the stock LP with a filter ahead of it to protect the pump and feed the stock filter/separator with a hose and banjo-to-barb adapter. I stuffed a greased rag into the output of the stock LP, and put a shipping plug over its inlet barb. In the glove box is the stock steel line, two Cu crush washers for the banjo fitting, a 14mm and 17mm open end/box wrench so I can restore the stock pump to service if I have to.
