...as long as my tank is out while I put in a 1/2" sender i figured I'd see if anybody has converted to an in-tank pusher pump using the wagon tanks. Wagon tanks have a set of baffles running transverse since the filler neck runs to the side instead of the plate. It also uses the old style 1978-1983 pickups. Anybody convert a 1978 era Regal Wagon to the pusher pump in tank?
You might want to check out www.turbowagon.com and see if he (Brian, whose email link is on the page) has any ideas. I assume, however, you are keeping a low-pressure system for a carb? -Bob C.
Bob there is no need to keep a low pressure system for a carb. You control the pressure to the carb with a return style regulator. I am going to try to post a link from a previous thread where I posted info and links that should be helpful. I think it also has info and link info for the regulator I have been running. www.v8buick.com/showthread.php?t=114331 PS You can also buy new aftermarket GN replacement or fuel injection tanks for G-bodys. They are reasonably priced for a new tank but do not have as much baffleing or fuel slosh control.
careful many EFI regulators can't drop down to 7psi. (efi runs at about 23psi for tbi and 43+ for port injection) and many carburetor regulators can't handle the input of an EFI pump. -nate
use an elcamino 4.3 setup if you can find,they had a throttle body on some of them,and gm tbi s only run 12-15 range
Nate, Well like it says in the linked post I used the Mallory MAA-4309. And yes the Walbro pump would normally run at like 43 psi with a factory non adjustable GN regulator. I have a T between the regulator and the carb so that I could run a line with a fuel pressure guage to my winshield wiper to check for drop off during a run. It stays constant the whole run. I even have a Q-jet which does not like as much pressure as most other carbs. Also like it says in the link I used this setup successfully for 9,000 miles. Before wrecking the car that is, which BTW was not my fault. Also I am currently moving the whole setup over to another car. But your point is still valid, becareful that the regulator you choose is up to the job.
Thanks for the help! Those won't fit into the Wagon. Pretty much everything behind the diff is changed in the Wagon G-bodies. I'll add that an EFI regulator stepped down to a typical reg will work fine...
. I second that all the tbi were around that pressusre a camaro may use a difffernt one wit a lil more flow. I was actualy thinkning of runnin twin in tank pumps on a street car i had you can easily modify the stock sump to make one or two fit depending on your application you should easily be able to manage around 400-450 wit one pump.
