Dennis you may want to look at what size fittings your current pump has. The 1791 has 3/8" fittings where the 1792 has 1/2" fittings. Not sure about the pressure part.
Yea, I know. Originally I had a Holley blue which has 3/8. When I went to the Paxton, it had 1/2 so I just used bushings. Therefore, I can use either one. Probably going to try the low pressure one.
That's good, with some of these fittings it is easy to eat up the cost difference pretty quick. Let us know how quiet it is.
For me, the only way to do is an in-tank pump. It's a little more work and a little more of a PITA, but it is quiet and they tend to last a little longer if the car is a driver. These guys installed a tanks-inc universal pump into a chevelle tank, which will be similar to a maverick tank. http://www.thedetailzone.com/Tanks%20Fuel%20Pump%20Install.htm
All the in-tank pumps I have seen are for fuel injection which usually has a minimum of 45 psi. Way to much for a carb. I dont know that you could regulate it down far enough for carb use. Maybe with a return line it might work, but that's more work than I want to do on this car. It definitely would be a lot quieter though.
OK, I got the Eddlebrock in. I used the 1791 low pressure one. While it is quieter than the Holly Blue and Paxton, it is not that much quieter. No problems running a low pressure pump through a regulator.
I am probably going to get blasted for this but,.......what's wrong with a mechanical pump? I raced a 10.30 sec @ 130+mph 347 Mustang for years with a Carter mechanical pump and my 427 Fairlane runs 12 flat using the same kind of pump. NASCAR cars all use mechanical pumps. Seems like a simple, inexpensive, and quiet solution.
Nothing wrong with mechanical pumps. I just like a cleaner looking engine without extras hanging off of it. Plus one less power robbing accessory.
in the tank are ok for racing, but for daily driver they suck. ive had two friends get stranded because their Ch&** in tank died on a road trip. ive replaced two mechanicals and an electric external on vehicles over the years during road trips and it took me less than an hour, including the walk to nearest town part.the stock electrical for a EFI ford bronco or truck will provide more than enough flow if you want to do like mavaholic stated and build a bypass setup. they are way quieter than the holley, ours sounded like a sink being turned on low. when the cheapy on my high boy goes out in a year or two i may consider that one.
It's funny this comes up about the old Holley Blue. I have the same pump for my Maverick, just not installed yet. My brother in-law has one in his '67 Firebird as well and it is so freaking loud. I asked the guys at the Holley trailer at the Autolite Nat's in Sonoma and they just laughed and said to me, that's the blue pump for you. They said that there is no known way to quiet that thing down. You just have to live with it. To me it's not as annoying as when people put gear drive on a SBC and act like they have a blower under the hood.
