ok ok.... i know some of you will give me a load about an engine swap problem but no one seems to be able to snwer my question over there soo here it goes.... my 88 camaro is a v-6 and in the repair manual it tells me the car has an in the tank fuel pump i was just wondering with my new 350 can i still use that fuel pump or is there some extreme measure i will have to take in order to breathe life into my new 350


thank you for reading my post

 

Different people do it different ways. You could drop the tank and install a sump and a mechanical pump on the block. What I did was to use the factory in-tank pump and bought a Malloy AFPR # 4309 I think. This way I didn't have to run fuel lines or drop the tank.

 

Well, the way you asked the question was a little disjointed over there.

But,...

If you use the in-tank pump, you must use a 3-port regulator that returns excess fuel to the tank to control pressure to the carb. If you use a dead-headed regulator (2-port), the pump will not have the flow it needs to keep itself cool and will burn up.

Another alternative is to use the in-tank pump (with the regulator) as a "pusher" pump to a mechanical pump mounted on the engine. Personally, if I was doing it, I'd use the in-tank pump w/reg by itself. Others will disagree, of course, primarily because in-tank pumps have been known to fail, but you need to weigh the pros and cons of each approach and make your own decision.

 

Well I ran a return-style Mallory FPR and kept my intank pump. However mine was originally a 305 TPI car and it has worked fine. But I have no idea if the V6 pump was the same as the V8 pumps, or is too weak for a 350 or what...
