What I learned...pumps
I have had several conversations w/ Weldon and also Brett Clow at Aeromotive..
1. Aeromotive pt # 11104, ELIMINATOR [up to 900 forced ind] -12AN feed to the pump w/ a 70 to 100 micron filter between the tank and pump. -10AN from pump to 10 micron filter. -10AN to "Y" block and then -8AN to both ends of the rail.
Return lines are from both ends of the rail, and is recommended to be -6AN, with -6AN line from reg to tank. Return tube at the tank should be opposite the feed line and extend down below fuel level. This helps cool the fuel B4 it's returned to the pump, and keeps air bubbles in the fuel at a minimum.
If using a check valve, the valve should be AFTER the pump and before the 10 micron filter.
The regulator, pt # 13109 can be used.
Filter pt # 12601, [10 micron] can be used in the -10 feed line. The pre-filter b4 the pump is pt# 12302. [100 micron]. It has -12An fittings on both ends.
2. Aeromotive pt # 11102, Pro-Series, [up to 1250 forced ind]
can use the same plumbing as the Eliminator on the feed side. The changes come on the return side lines, and the regulator size.
It's recommended to use a -8AN off the rails to the reg, [pt # 13110, Pro-Series reg].
It is also necessary to use -8AN as the return line.
3. Weldon recommends the 2015 to 800 HP. You can order the pump, using the "B" prefix to get the -12AN inlet and the -10AN outlets. It can be plumbed the same as the Aeromotive Eliminator pump.
The regulator is pt # 2040. You have to specify the bypass orifice,[.200 for hi pressure] what fuel you are using, [gas or alky] and the desired pressure range. [dash 120 for a range of 30 to 120psi]
The next step up from Weldon is the 2025, good to 1300 and then the "NUCLEAR" pump, the 2035.. for over 1300!! Not going to use these, so I did no research....
IF you are using a stock tank, DO NOT block off the charcoal cannister line to the tank!! You will shut off the vent and the pump WILL get hot, boil the fuel,possibly fail and do all sorts of nasty stuff to the system!!
HTH,
