Why not more RASP?

[Coolslice]

I'm looking down the road at some future mods, and like everyone else I need to do something about the stock fuel system. . To me, it looks like the RASP is the best route to go but I almost NEVER see or hear of anyone using it here. . I'm just curious as to why nearly everyone chooses the FASS over the RASP considering... . Any thoughts?

I asked a similar question to see if anyone was using the RASP on 2005 Dodges with the in-tank lift pump. Guess not. I got no replies about it. Anybody??? I like the reliability of it. Only maintenance you need to do is change the belt every 50,000 miles. And if does go out the oem lift pump is your back-up. The only thing that makes me leary is that it partially hangs below or is level to the front intercooler. Almost an easy target to get knocked off if off roading.

I'm with you. That's the ONLY drawback I see to it but I don't think that would be a factor to most. . Most of the bombers seem to be pavement pounders. I'm not knocking the FASS, but I have read of problems with them. I have not read of any problems with the RASP but that may be due to the fact that there are relatively few of them out there.

I think some 2ne gens are running it. But is not very common on 3rd gens I agree.



For me I chose the easiest one, and that was thr HPFP from Fass - The RASP was way to involved for my install ability/wants

That's true about the only drawback. I'm not much of a dirt rider anyways. Was thinking just in case I do. I'm not knocking FASS either. Just wouldn't want to be that lucky one with the problems down the road. There are many guys who are using it flawlessly though. RASP is a good alternative. I think there's not many RASP users due to the advertising and not that many users with input on the system. There's also Airdog but I beleive their price has gone up to about a grand. Someone correct me if I'm wrong. There's a few RASP users on the 2nd Gen forum if you search there. I thinking about getting a RASP eventually but once again funding is a factor. But then that's why I'm doing my researching.

I use a rasp but it is on a 2nd gen though. Why more people dont use them I do not know. It is not complicated to install at all. It might be a bit confusing if you were to round up all the plumbing parts but if you buy one of the kits like Olee's for example it is all inclusive and not that difficult install at all. Or if you sit down and think through the parts needed again wont be that hard. As far as the RASP hanging down a bit low in the front. Well it does use the front four oil pan bolts for the mount but too be honest if you crack the RASP off wheeling you are more than likely going to be having much worse problems than that and the RASP may be the least of your worries at that point. It is fairly well protected by the front crossmember and especially if you have a DSS on the front end.

My main problem is the cost. I would prefer the Rasp but finances dictate stock lift pump. To some people finance is not an issue, I unfortunately am not one of them :{ . Pretty much everything I have done is out of necessity and the fuel delivery may become one of those eventually.

Unless it was a stick or something that flew up the pump would never have a problem off road. The bumper, radiator, and intercooler are way lower then the pump in the front and the anti-sway bar is right below and slightly behind the pump. So the odds of tearing one off aren't good. In order to run it on a truck with the in-tank lp you'd need to drop the tank and put in a new pick up tube. I have one on my 04. 5 and it works flawlessly. 14. 5psi at idle and 20-21psi under full power at high rpms.

on the 04. 5, was there some issues with fitment on the front of the engine and having to grind something down to fit?

I ended up trimming my fan blades originally but it has been made to work without that now I believe. I would call DTT to verify though. I trimmed mine because I was worried about the blades flexing under high speed and hitting the belt but it turns out the blades move forward at high speed instead of back.

my . 02 is that the RASP is the most logical choice. that is - engine RPM increases and fuel pump output increases. my reluctance to buy one is about price right now. that plus the stock system is still working for me. maybe in summer time.

Two words: COST PROHIBITIVE! Going to replace LP #4 for #5 tomorrow night. I wish I had the funds but there's always bigger priorities. Come on Lotto! :-laf

man with that kind of record, I would consider another pump maker.



I have not had a lick of trouble from my HPFP from FASS/DPP - other than not enough fuel for a modded CP3 (who'da thought 95gph was not enough????)

 

[klaybus]

I think with 175k & counting thats pretty normal for these Cater pumps. I installed the Vulcan relocate & 1\2" line kit which works superbly but it's the friggin by-pass on the Carter that keeps failing! I'll do another Carter for now but I see a change of sorts in my near future. The last LP went 8 months or about 20k miles...
