Fuel pressure low?

[Cwhatfield40]

LOL yes, just an assumption on my part. There are many types. I used to work at a speed shop and install adj fuel regulators on everything from MR2s to Mustang Cobras. The less expensive ones used a lock nut on the adjustment screw... some had a nifty spring bound thumb screws without a locking nut. One Corvette had one that had a recessed hole for a jewelers screw driver. On return-less fuel systems we actually changed the voltage to the fuel pump using a boost-a-pump system.
However, the BBK and Kirban regulators use an allen-set screw with a locking nut. Desi will have to determine how his works. (if you start tweeking stuff, be sure to count the number of turns so that you can return to the original settings should you have bad results)

Fuel filter for fuel pump replacement cross reference

I could not find Fram or NAPA filter locally to replace my inline fuel pump, so I had to find a cross reference:

FRAM G3850
NAPA FIL3296
AC Delco GF643 (original equipment on 2008 Ford Escape Limited V6)
Luber Finer FF745 (Autozone)
Ryco Filters Z534
Motorcraft FG872
Purolator F64711
Kralinator G213
WIX 33296
Baldwin BF1166
Acklands Grainger BWNBF1166 (Canada only)

OK, so I dropped the gas tank and found some other problems even before I got to the pump. The vent grommet was all shrunk up and had been leaking gas all around the top of the tank. The filler neck grommet was also cracked and leaking. I thought I smelled gas when the tank was full.
The pump was shot, it was leaking through the top of the pump.
Also, the hose going from the pump to the steel line had ruptured... most likely why it seemed to quit working all of the sudden.
I actually ran the pump and watched it through the filler neck opening and could see it spraying gas all over.
Then I tried to modify the 84 pump bracket to install the Walbro pump. Needless to say I was unable to cram FRANFEN-PUMP into the hole. So Monday I will order a pump bracket.

Get some new gaskets for the flanges too. Mine were hard as rocks on the sender and pump.

[Cwhatfield40]

Good idea!

I got them and new lockrings. Had to get them from a local Mom & Pop parts place my Dad used to use when I was a kid. I paid them and they gave me the invoices and I hit the 2 distributors (were acually on my way home) to get the parts. Didn't want to wait forever for on the the big places to get them.

[Cwhatfield40]

Yeah, I found a Ford dealer 45 minutes away that had the lock ring and fuel sender gasket. They are the most expensive, LRS was cheaper, but hey, I got to poke them and compare parts before I purchased them. I already had all the rest.

I received my new pump hanger yesterday. It even came with a new locking ring and gasket. The wires on the hanger are 14ga silver tinned copper. Good for 15 amps without getting warm. I soldered and spliced the wires though, I didn't want to heat up the feed-thrus on the bulkhead connector. I also have a habit of drilling out the metal fittings with a 1/4" drill bit. I try to keep the smallest diameter restriction in the system no smaller than the pump's output port. You must have good files and clean up practices when modifying the quick disconnect ends, other-wise you can trash many pieces of the fuel injection system. On my turbo XR7, I measured the flow rate unmodified with a 190lph pump... it was only 150lph! So I reamed every fitting I could get to and only then did it actually put out 190lph (more like 199-205 from several tests).

[Cwhatfield40]

Finished. I like it cause it is shiny!
I ended up making a 1" hole with a Greenlee punch in the end of the bracket and just connecting the fuel line directly to the filter. There was plenty of slack. I had a scare when some of the quick disconnects leaked... I had to replace the viton o-rings on 2 connectors. Time consuming.

If I ever get around to putting in dual exhaust, I will buy a filter bracket to go over the axle and use later model fuel lines.

For future reference, if you don't want to add another filter or drill holes, take a look a Dorman part # 800-159. The kit has 2 adapters. One is 5/16 X 12" quick disconnect double ended tube and the other is 3/8". It is $25, but saves a ton of space and time while you under the car. I found it in the self-help section at Advanced Auto Parts.
