Engine/Transmission (1998.5 - 2002) pick a pump any pump

[edgerat]

If you had a choice between a cam with 12v lift pump or any of the aftermarket fuel pump options out there, including the MITUSA and RASP which would you do? Money isn't an object so I want to hear what you would choose for a 24v truck if you were trying to bulletproof the fuel system. FASS is not an option

From what I've learned, speaking with other fellows at events and here - the P pump on the 12v's are very reliable. The consideration on converting is "are the $$$ required to convert to a P pump worth the end result/can you build high hp/tq, or equal to the hp/tq outcome with a properly balanced/built VP system?"



MHO - nothing is bullet proof - even a nine inch locker - don't ask how I know this :-laf . But, I know you're looking for what's "as fail proof as possible" - in my book anything that's "as fail proof as possible" (even that old nine inch) is as close to bullet proof as we'll ever see. Back to topic . . .



So far when a friend of mine and I asked the P Vs. V pumps question we got mixed replies. Most of the 12v guys said it's easier to build HP with the P pump it's more reliable. Most of the 24v guys said they'd take the money you'd have to spend to convert and do much better with a VP type pump and electronics.



So, "let the games begin" :-{} . You'll likely get tons of opinions eventually. Did you put this post in the 12v section also. Might be a good idea to hear both sides of the "valved" opinions. :-laf



Good luck to you whatever you do.

Edge, are you asking about replacing the injection pump? Your question looks more like you asking about putting a mechanical lift pump feeding the VP. From what little I know I don't think that's a good idea. The mechanical lift pump from the 12V puts out some pretty serious pressure spikes and from what I've heard about it it will kill a VP pretty quick.

Thanks Batphreak.



There I go "thinking" again - all I saw was 12V - 24V and pump - Duh! and associated it with what my friend and I have been asking / wondering.



I agree, if you are looking for an "LP" Vs. "IP" = my dumb reception of your thread - I waited a long time (5 POS Carters) and watched customer comments about the other LP companies before making my choice. See signature.



Once again, thanks to Batphreak for reprograming what's left of the grey matter.

Sorry about that guys, I meant the lift pump. The best option that I have found so far is the 12v lift pump with a cam on my 02 SO truck. The GDP setup by the time it is installed is 800, same with the FASS and the other options. I can get the DD cam for 1200 and then get a GREAT deal on the install so for less than double the price of the electronic pump I can get the best mechanical option along with the added benefit of the cam.

the matusa is a great set up

Not a problem.

My turn for a question. Got a link for this Matusa? Google didn't turn anything up, is this some kind of new mechanical solution?

i dont off hand but i will see if i can get it some how, it is accually belt driven and is a mechanicle pump looks great and is said to be the most reliable, but pricey

edgerat - I hate to post prices, but my GFS-392, 2 micon set up and big lines cost me under $500, shipping included too? And, if you want to get a spare pump they're about $100 and change out in like 5 minutes with a few wrenches.



Not trying to kick the RASP or the like - I see lots of happy customers with this product repling here and on other sites - so I was considering one myself but, read that if it fails you are Out of Commission (usually happens when you are beating the beJimminies out of your truck or out in the middle of no mans land - Murphy's Law is always in effect) until a new one arrives - am I correct here RASP guys? This also is only what I've read here about them before making my choice.



Also, only what I've read here, you don't have anything to build psi before the engine starts unless you maintain an electric LP? RASP guys please reply.



Not being a smart arse - just trying to help a fellow making a decision and learn from those that have the RASP type mechanical systems.



Thanks.
