Yup, the RP pump that I replaced YEARS ago starting having low fuel pressure when we entered NC. We stopped, up the pressure and things seemed ok. Then we met up at the damn and whenever the secondaries came on, the thing fell on it's face and FP went to like 15psi with the fuel pump screaming like a stuck pig. So that first night we pulled the pump and found the sock pretty well clogged. So we let that sit in acetone overnight.
The next morning we reassembled and went to the show. The sock was flowing MUCH better. Tried boosting on the way there and the same thing happened. As soon as the secondaries came on - splat. The pump started screaming again so we figured the pump went bad. So luckily Bryan from RotorSports Racing was having a special on the cosmo pumps so I bought one and myself, AJ, (duffman) and Scott (TurboIIRotor) pulled the entire rear of the car apart (for the second time in 12 hours) to replace the pump and sock right in the middle of the show

So we get the thing back together and the same shit, as soon as boost hits, the pressure goes to nill. Now I'm pissed, the world turns red and I start looking for virgins to rape and pillage. Missed the Dragon run and head back to the cabin. At this point it's either the reg or the filter. Reg is fine, filter is CLOGGED. So we make an hour drive to the nearest advanced auto to get a phord 3/8 barb EFI filter, then to Lowes for some 1/4"npt to 3/8" bard fittings and back to the car to put the thing together. FINALLY fuel pressure. So we went to the banquet, and drove the dragon the next day in the rain, which was still a blast.

Car ran great all the way home and it wasn't until a day or two later that the fuel pressure started getting a little low, nothing to cause concern but fluttering a little lower than usual. I bought the Marren washable stainless filter and put that in saving the fittings and hose from the EFI filter just because. and now everything is fine again.

Few weeks later I order a bosch 044 pump and intank sock and install that. MOTHERFUCKER was that thing loud. PAINFULLY loud and it seemed to get louder the longer you drove it but then would quite down after you restarted it. Apparently that's "normal." The pump pissed me off to the point that I changed it out. When I pulled that pump sock was getting clogged. Now I'm pissed again and drop the tank and clean it out by hand. Wiping everything down with a paper towel and it was coming out as white as it was going in. Now I'm confused. Whatever, I clean the cosmo sock, put that back in the tank that I'm convinced is clean, set the FP and head off to the dyno. My FP sender pukes on the way to Dave but it was set before so I'm happy. Then the thing goes way lean on the dyno and we can't figure out why. We start pulling lines and making sure everything is as it should be. I remember now when we pulled the feed line off at the tank there was ALOT of pressure between the pump and the filter, didn't think much of it at the time. We can't figure out what the problem was so we put everything back and I head home. I used the overall fuel trim to add 10% across the board and had to bump it to 15% and then 20% to keep the lambda's in check. What was happening was the sock and the filter were getting clogged, again. I found this out when I got home and pulled the filter, poured in some acetone and none came out. My thoery, the bosch flows so much more and doesn't drop off at the higher pressures that it was able to just force fuel through the filter but the cosmo pump couldn't.

So I cleaned that washable stainless filter, bought a new cosmo sock, put a new sender in, SWAPPED FUEL TANKS and a week later went back to Dave. Did the comp test and found two low bounces in the front. We went through the entire map and the datalogs and found nothing wrong. So now the anger has turned to depression and we left. Driving home I'm thinking fuck this car, this is retarded, 4 motors in 4 months? BOOOOOO, this car is getting jack standed till Oct when I do everything else that I want to do. About 2 minutes later a Prosche Carrera 4S comes racing down the on-ramp, my buddy made a comment like, there's a car you could beat up on when the motor's put back together. Fuck that, I'll beat up on him now. So we start fucking around and I started pulling on him in 4th @ ~120 before I almost ended up underneath a tractortrailer. Now I'm thinking, fuck that Oct bullshit, this engine's getting hauled tomorrow. And it was, within 4 hours a close friend and I pulled the engine, stripped her to a shortblock and had her in the back of my truck. 2 days later I was back @ KDR so we could break her down and see what happend. That's when we found the two warped Apex seals. So I left everything with Dave for cryo and now I'm planning on snagging those this week.

So I know the filter was clogged while on the dyno. I also have come to find out that the ethanol is breaking down fiberglass fuel tanks in the marine world. 5-6 years ago when I started restoring the car I dropped the fuel tank. It was all sorts of nasty so I went to a machine shop, had them boil it out and epoxy coat it. I'm almost certain it's the ethanol breaking down the coating and clogging everything up. I'm AMAZED the injectors are fine.

So yeah, that's my story, ethanol blows moose. Cost me an engine.
